Science and Technology Log:

Greeting from the Bering Sea!  It was a long journey to get here, complete with bad weather, aborted landings on the Aleutians, a return and overnight in Anchorage, and lost luggage, but it was a good introduction to the whims of nature and a good reminder that the best laid intentions can often go awry.  As O’Bryant students know, our motto is PRIDE and the “P” stands for perseverance, so I simply stayed the course and made it to Dutch Harbor and NOAA Ship Oscar Dyson… only 29hrs late!

In upcoming posts, you will learn a lot about the acoustic technology, statistics, and the engineering know-how behind the trawling process and how it is used to find, collect, and study Pollock populations.  But first, let’s start with splitting open some fish heads!

Now that I have your attention, let me explain.  There are many steps involved in “processing” a net full of Pollock, and I will show you each soon, step-by-step.  I think it would be more fun, though, to jump ahead and show you one little project I helped with that literally had me slicing open fish heads…

Hard at work…

Here I am preparing and cutting away!  The objective: remove the two largest otoliths, structures in the inner ear that are used by fish for balance, orientation and sound detection.  These are called the sagittae and are located just behind the fish’s eyes.  These otoliths can be measured– like tree rings — to determine the age of the fish because they accrete layers of calcium carbonate and a gelatinous matrix throughout their lives. The accretion rate varies with growth of the fish– often less growth in winter and more in summer– which results in the appearance of rings that resemble tree rings!

Time to cut…

From a small sampling of otoliths, along with length data, projections can be made about the growth rates and ages of the entire Pollock population.  Such knowledge is, in turn, important for designing appropriate fisheries management policies.  Fisheries biologists like to think of otoliths as information storage units; a sort of CD-ROM in which the life and times of the fish are recorded.  If we learn the code, we can learn about that fish!

Can you spot the otolith?

For each net of Pollock, we will collect 35 otoliths, which translates to approx. 1,500 otoliths from this cruise alone!  They will be sent back to Seattle and measured under the microscope this fall and winter.

Finished!

Personal Log:

Wondering where I am at this very moment?  Check out NOAA Ship Oscar Dyson on NOAA Ship Tracker!

Small things become important when your daily life gets confined to a small space, right, students?  Perhaps some of you have been to sleepover camp and know firsthand?  In a few years, you will also experience communal living in close quarters— in college!  It only seems appropriate that I start by explaining to you (and showing you) my personal space aboard NOAA Ship Oscar Dyson!

First, my stateroom.  This picture shows you that I am in room 01-19-2.  I am on the 01-deck, and there are four other rooms on my hall that house most of the NOAA science team- Taina, Darin, Kresimir, Rick, and Allan.  Allan is my partner in crime- he is the other “Teacher at Sea” (TAS) onboard this cruise; he teaches high school science in Florida!  In addition to the NOAA team, Anatoli is a Russian scientist on board.  These NOAA scientists are based in Seattle in the Midwater Assessment & Conservation Engineering (MACE) group at the Alaska Fisheries Science Center and, depending on their schedules, come out to sea 1-4 times per year to collect data.  They are just one group of many NOAA teams conducting research in the Bering Sea; you will learn much more about the science team in later posts.

My door

Originally, I was going to be bunking with the Chief Scientist, Taina!  However, one of the scientists was unable to join the trip, so Taina has her own quarters and I have mine!  This is quite the luxury, and it is very nice to know that I do not have to worry about waking up a roommate as I get ready for my shift.  Most roommates have opposite shifts, so each person gets at least a little bit of “alone time” in his/her room.  For example, Allan’s shift is 4am-4pm (0400-1600) and Kresimir’s shift is from 7pm-7am (1900-0700).

Here is my bunk!  I chose the bottom one, so if I fall out in rough seas, it is a shorter fall!  One trick- if the seas are rough, take the rubber survival suits and stuff them against the metal frames, so if I do smack against them, there will be some padding!  There is a reading light inside, and I also brought my trusty headlamp and pocket flashlight, so I should be pretty well set on any hasty exit I may have to make- such as for a safety drill!

My bunk!

I also have a desk and a locker, which is a closet for my clothes and other gear.  One thing ships excel at is maximizing small spaces with hooks- I have a row of hooks for my jackets, sweatshirts, hats, etc.  In the head (bathroom), there are many hooks as well.  The other neat trick—the use of bungee cords!  Here is one holding the head door open so it does not swing back and forth as the boat rolls.  They are also used throughout the ship to secure desk chairs, boxes, and any other object that could take flight during rough seas!

See the bungee cord?

Since it is summer here in the high northern latitudes, the days are very long—sunset does not occur until about 12am each night and sunrise occurs around 7am.  The ships provides shades on both the bunks and the port holes (windows) to help people sleep, but as you can see, the earlier tenant in my room even added a layer of cardboard!

My window…

There are a few other features that help define life at sea.  The shower curtain has magnets to help secure it to the walls.  As you can see, it is a pretty tiny shower, and that handle could become essential if I chose to take a shower and then the seas turn rough!   The medicine cabinet locks shut, and if you leave it open, the door can swing during a big wave and smack you in the face!  Lastly, the head includes special digesting bacteria, so you can only use a special cleaner that does not kill them by accident!  There is a very powerful FLUSH noise that takes a little bit of getting used to as well– it scared me the first time I heard it!

Spot the shower handle…

That about does it for our first tour.  Please post a comment below, students, with any questions at all.  In my next post, I will give you a tour of the second most important area in daily life— the mess, where I eat!

Virtual Tour of the Oregon II

I know many of you may have never been on a ship before and are probably curious to know what it is like to be aboard the Oregon II. I’m going to take you on a little virtual tour, but first you will need to know some common terms that are used to refer to certain areas on the ship.

Ship Term	What It Means
Bow	The front of the ship.
Stern	The back of the ship.
Starboard	The right side of the ship when facing the bow.
Port	The left side of the ship when facing the bow.
Forward	The direction towards the bow of the ship.
Aft	The direction towards the stern of the ship.
Bridge	The location of the command center for the ship.
Galley	The kitchen.
Mess Hall	The dining area.
Head	The bathroom.
Stateroom	Where crew members sleep.

On Deck

The Bow

At the bow of the ship is where most of the scientific collection equipment is deployed/released. The CTD (conductivity, temperature, depth), the neuston net, and the bongo nets. (I will talk about each one of these in upcoming blogs.) There are several large cranes that help lift these up off the deck and swing them over the edge of the ship to be released into the water. When you are at the bow and the cranes are running, it is very important to keep yourself safe. Everyone who is at the bow when the cranes are operating is required to wear a hard hat and a PFD (personal floatation device). You never know if a cable will snap or the wind will swing the equipment towards you. There is a sensor on the PFD that is activated when large amounts of saltwater touches it, like if you were to fall overboard. Once salt water touches the sensor, the PFD will inflate and keep you afloat until you can be rescued.

Oregon II Bow

The Stern

At the stern is where the samples from the neuston cod end and the bongo cod ends are collected and preserved in jars for scientists to examine at a lab. This is also where the large trawling net is deployed. The scientists spend most of their time at this part of the ship.

Stern of the Oregon II

What Makes the Ship Sail?

Bridge

The bridge is where the officers of the Oregon II work. It is located toward the bow of the ship. The bridge has all of the navigation tools necessary to steer the ship to the next sampling station. There is also a lot of weather equipment that is monitored and recorded throughout the day. The bridge is where you’ll find the best views of the ocean because it is almost completely surrounded by windows and it’s higher than any other room on the ship.

At the Helm

Bridge

Chart Room

This room is where all of the maps are stored. While there are more technologically advanced methods used for navigation on the ship located in the bridge, it is important to have physical maps on hand to refer to, especially if the instruments stop working for any reason.

Chart Room

Engine Room

Before we untied our ship from the dock I received a full tour of the engine room. This is where the heart of the ship is. Everything in the engine room powers the ship. Our water is even purified down here using reverse osmosis (passing water through a membrane to filter the water). Because of this machine, we can filter salt water into fresh water to use on the ship.

Reverse Osmosis Machine

It was great to venture down to the engine room  before we set sail because I was told that it can get up to 110 degrees when the engines are running! It is a large space, but it feels small because of the large equipment. There are two of everything, which is especially important if something needs repair. Below is a picture of the two engines. The other is a picture of one of the generators.

Living on a Ship
Stateroom

My stateroom is compact, but its main purpose is for sleeping so size isn’t really an issue. There is a bunk bed, a sink with a mirror, latching drawers for clothes, and a hide-away desk. There is also a compact tv that is attached to the bottom of the top bunk and folds up when it is not in use. I only use the room to sleep and get ready for my shift because my bunkmate works the opposite watch shift as mine (midnight to noon), and I want to be the least disruptive as possible. After 12 hours shifts, sleep is really needed and helps reenergize you in time for the next watch.

Stateroom Bunks

Stateroom

The Head

The head is the same as a bathroom. On the Oregon II there are private and communal heads. The private heads are for the officers and are typically connected to their staterooms. The communal heads are open for any crew member to use. There are also communal showers for the crew to use. All of the toilets use salt water that is pumped onboard. The reason fresh water is not used is because it is a precious source on the ship and is not readily available from the ship’s surroundings. The sinks, showers, drinking fountains, and ice machines all use fresh water. Fresh water on the ship should never be wasted. Water for the sinks is timed so that there will never be a faucet that is accidentally left on. Showers are to be kept to a maximum of 10 minutes, though it is encouraged that they be even shorter.

Heads

Shower

Galley and Mess Hall

This is one of my favorite places. The galley is where our ship’s cooks prepare all of the wonderful food for the crew. The mess hall is where we all eat during meal times. During meal times it can be quite crowded in the mess hall as there are only 12 available seats and over 30 crew members onboard who are ready to eat. There is an “eat it and beat it” policy to help ensure that everyone who comes down to eat will be able to find a spot. Despite this, it is still a great way to converse with the crew and talk about events from the day before giving up your set to another hungry crew member.

Galley

Mess Hall

Crew Lounge

This is the place where crew members who have some down time can gather and socialize, though down time can be rare. There is satellite tv, a couple of computers, and hundreds of movies to choose from. Some available movies haven’t even been released onto DVD for the common household yet, but they are available to the military. They do this because not everyone has access to current movies when they are away from home for extended periods of time. All of the DVDs are encrypted and can ONLY work on the machines aboard the ship. I was excited to find a copy of The Hunger Games and I plan on trying to watch it before my trip is over.

Lounge 1

Lounge 2

Labs on the Oregon II

The Wet Lab

The Wet Lab is where all of the samples from the groundfish trawls are sorted, counted, measured, weighed, and sexed (gender identified). Buckets filled with animals from the nets are dumped onto a large conveyor belt and spread out to make sorting the different species out into individual baskets easier. Everything in the wet lab can get wet except the sensors connected to the machines. We need to be cautious around the sensors when we are cleaning up after a sampling so as not to get water in them.

Wet Lab

The Dry Lab

The Dry Lab is where all of the computers are located that record all of the data from the samplings. As the name of this lab states, everything in it is dry. Water should never come into contact with the equipment in here because it can seriously damage it. In between samplings, this is typically where the scientists gather to wait for arrival at the next sampling station.

Dry Lab

The Chem Lab

This is where all of the plankton samples are stored. It is also where water samples taken from the CTD are tested for dissolved oxygen (DO). The CTD does have its own DO sensor, but it is always best to test something more than once to ensure you are collecting accurate data.

Personal Log

Day 1 – July 5th

I arrived in Gulfport/Biloxi, Mississippi late in the afternoon of July 5th. The chief scientist, Brittany Palm, met me at the airport and drove me over to the Port of Pascagoula where the Oregon II was docked. We met up with two college volunteers, Kayla and Andrew, and got a quick tour of the ship  (the air conditioning was out!) before we headed over to a wonderful local barbecue restaurant. We returned after dark and were welcomed with a fixed AC! I unpacked my belongs into my latched drawers and made up my bunk bed up so that everything would be in place when I was ready to hit the sack. It took a couple of nights for me to get use to the sounds of the ship, but now I hardly notice them.

.

Day 2 – July 6th

When I woke up the next morning, I decided to venture out into downtown Pascagoula which was only a 5 minute walk away from the ship. It is a quaint area with little shops and restaurants. I met up with the two volunteers and we picked a business that had the best of both worlds, a restaurant and a shop, to have a wonderful breakfast. We had to be back on the ship by 12:30 for a welcome meeting, but we took some time to snap a few pictures of our floating home for the next 12 days. We were underway shortly after 2 pm (1400 hours in military time). It was fun to watch our ship depart from the dock and enjoy the light breeze. It wasn’t long until we had another meeting, this time with the deck crew. We learned about the safety rules of working on deck and discussed its importance. The rest of the afternoon was spent relaxing and getting my sea legs. The gentle rocking does require you to step carefully, especially when you have to step through the water tight doors!

Day 3 – July 7th

Our first day out at sea was slow to start. We didn’t reach our first sampling station until early in the morning on the 7th, even though we left the Oregon II’s port in Pascagoula mid-afternoon on the 6th. I was sound asleep when we arrived because my shift runs noon to midnight every day, so my first sampling experience didn’t happen until almost 24 hours after we set sail. This was nice because it gave me time to explore the ship and meet some of the crew.

.

Right after lunch I got to jump right in and help finish bagging, labeling, and cleaning up the wet lab for the team that was just finishing up their shift. After we had finished it was time to conduct my first plankton sampling.  We went out on deck at the bow of the ship to prepare the CTD (conductivity, temperature, depth) device for deployment/release. After the CTD was released and brought back on deck, we deployed the neuston net to collect species samples from that same station. (I’ll explain the importance of this type of net in a later blog.) Once the collection time was complete, the neuston net was brought back on deck where we detached the cod end and placed it into a large bucket. Cod ends are plastic cylindrical attachments with screened holes to let water run through but keep living things inside during collection. The neuston cod end’s screens have 0.947mm sized openings.  We then deployed the bongo nets to collect samples of even smaller species like plankton. (I will describe the purpose of the bongo nets in a later blog.) When the nets were brought back on deck, we detached the cod ends from the two bongo nets and placed those into buckets as well. The screens on the cod ends for the bongo net are even smaller than the neuston’s at only 0.333mm. When all of the nets were rinsed to make sure nothing was still stuck to the inside of the nets, we brought the buckets back to the stern of the ship to further rinse the samples and place them into jars for further examination by scientists.

Day 4 – July 8th

Holding a blowfish collected from a trawling

Today was a lot of fun because I completed my first groundfish trawl. The net for this trawl is located at the stern of the ship. When the net was brought back up on deck, it was emptied into a large box. There was quite the commotion when the fish were emptied out of the net. Not only were the fish flopping around like crazy and splattering water everywhere, their scales flew everywhere and it looked like shiny confetti! Anyone who was in a 6 foot radius was bound to be covered in scales. By the end of the day I thought I was part mermaid with the amount of scales that had stuck to me!

.

There were so many fish in one of our trawls that we had to use large shovels to place the fish into more manageable sized baskets. The baskets were brought inside the wet lab to be sorted, weighed, measured, and labeled.

.

The coolest animals I saw today were sea urchins, a sharpnose shark, and a blowfish. It was also fun to observe the different crab species, so long as I kept my fingers away from their claws!

.

Question of the Day

There is only one right answer to this question. ? You’ll be able to find it at one of the links I placed in my blog. Can you find the answer?

Good Luck!

Scientific Log:

I’ve received an in-depth tour of the ship and labs, and I am starting to piece together how the “Acoustic Trawl Survey” works. Basically, NOAA is responsible for monitoring the populations of walleye pollock and accomplishes this task in several ways. The acoustic trawl survey is one part of how this is done.

Net Reels

The science team identifies particular transect areas in the Gulf of Alaska. The ship travels to that area, then transmits acoustic signals about once per second as it travels along each transect. The returning echo gives scientists an initial measurement of the abundance of organisms in the water below the ship. Just “listening,” however, is not enough. We also have to sample populations physically to determine the ages, sizes, and species of the organisms. The ship trawls for these additional data.

A trawl is a large net towed behind the ship to catch fish and other organisms. The individuals (of all species) in the catch are identified and counted. Cameras (three) are mounted inside the back of the trawl (codend) to collect images as they pass through the trawl. From this larger catch, a sample of the walleye pollock (about 300 individuals) are dissected to determine sex, diet, measured (length and weight) for size and aged by looking at (yes) their ear bones or otoliths. I’ll cover all of this in depth once I have been able to do it and see it in action, but that is the gist.

Personal Log:

I think first impressions are important. Alaska? Alaska is impossibly big and impossibly green. Too big, perhaps to describe with common adjectives. It took me about two days of travel from the 4-Corners to make my way up here: a Beechcraft 1900 from Cortez to Denver, then flights from Denver to Seattle and Seattle to Anchorage. I spent the night in Anchorage and wandered the city at midnight… …not that you can tell that it was so late from the pictures.

The next morning I took off from Anchorage and met up with the crew and scientific party onboard the Oscar Dyson in Kodiak, an island the size of Connecticut in the Gulf of Alaska

Adventures in a Blue World, Issue 6

As for how ‘impossibly green’ Alaska is, I was thinking about the reasons Georgia O’Keeffe gave for moving from New York City to New Mexico in 1949. She said (and I paraphrase) that she wanted to use more vibrant colors in her palette of paints than just green. Ms. O’Keeffe would have it rough here in Alaska: greens, greys and blues abound. Adventures in a Blue World Issue 6 may not convince you of the colors of Alaska, but I hope it gives you a grasp of its size.

Kodiak, Alaska dock

I’ve already settled in to the ship and my stateroom. My stateroom is small but comfortable, and I share it with a woman who is part of the scientific NOAA team. Interestingly, she worked for the same professor at the Rocky Mountain Biological Laboratory in Gothic, Colorado as an undergraduate that I did. Very Small World.

We are docked in Kodiak for a few more days than anticipated: we are awaiting the arrival of another deck-hand, and there are a few repairs that need to be made to the ship. Once we get started, I will be working the 4am-4pm shift, and taking part in whatever science is taking place. In the meantime, I get to ‘nose around’ Kodiak, go for hikes and runs, check out museums (see below), and eat as many salmonberries as I can stuff into my mouth.

Until our next adventure,

Bunk beds

Since we haven’t yet arrived at our first fishing spot yet, I’m going to let you all know what life has been like onboard the NOAA Ship Oscar Dyson.  I am on the 4 a.m. – 4 p.m. work shift, but since we haven’t been doing much in terms of trawling/collecting fish, I haven’t had to get up at 4 in the morning yet!  Another day or so (definitely not tomorrow, I’m told) and I will have to re-adjust my sleep schedule so I can wake up at 3:45 for my shift!  But for the time being, I’ve been waking up around 9:00.  Breakfast is served in the mess hall from 7-8, but I’m a cereal junkie, so missing the hot breakfast is no big deal for me.  Speaking of cereal, I just had Life for the first time and love it

The teeny tiny head. Smaller than any dorm bathroom I've been in!

My whole stateroom. Not much room!

Back to my day.  When I wake up, I have to be very quiet moving around my stateroom because my bunkmate works the 4 p.m. – 4 a.m. shift and is still sleeping.  I first head down to the acoustics lab one deck below my sleeping quarters to find out what’s on the agenda for the day.  So far, it’s been a lot of trials/test runs to see if all the equipment is working properly. I’ve also spent some time with the other scientists that are on the day shift with me, and they’ve been great at explaining how they use sound to help them locate fish.  When I’m not with the science team, (which so far, has been fairly often!) I’m usually in the lounge and/or conference room watching movies or reading.  There are over 1000 movies on board!  I try to stay out of my stateroom because my bunkmate is asleep, so I try to take everything I might want for the day with me- Kindle, camera, computer, iPod.

After my shift ends at 4 p.m., I either read some more or go to the “gym.”  There are actually two gyms on board, each with a treadmill, elliptical, stationary bike, etc etc.  I definitely need to go after all the great food I’ve been eating on this trip!  Adam and Joe, our stewards, always make sure to have a variety of delicious foods out at every meal.  Here’s what was on the dinner menu tonight:  bacon wrapped tenderloin steak, shrimp & crab St. Jacques, twice baked potato, green beans, and focaccia bread.  In addition, there’s always salad fixings to choose from.  I’m eating better here than I do at home, so stopping at the gym is necessary.

After dinner, I head back to my stateroom to shower and update my blog  Showering on a moving vessel is quite an experience, and tonight was actually the first time I had to hang on to the handle in the shower- makes it very difficult to wash your hair with one hand!  Then I read or watch a movie, and head to bed.  I’m on the bottom bunk (because I got to the ship 2 days before my bunkmate!), which is better in terms of the motion of the boat.  Less of a chance to fly into the air and fall out of bed  Our bunks have a little curtain that wraps around them, so we can block out as much light as possible- remember, way up here in Alaska it doesn’t get dark until well after midnight, so I need that curtain!

That’s about it for my shipboard life so far.  I know I keep saying that we’ll get to work in another day or so, but I promise, we’re starting tomorrow!  Be on the lookout for more science-y logs from me.  We are back in some rough seas again, so I’m taking some Dramamine and hitting the sack!!  Let me know if you have any questions about ANYTHING!

Science and Technology Log

Safety is very important on NOAA Ship Henry B. Bigelow. We participated in a Fire Drill and an Abandon Ship drill today. Each person on board is assigned a location to “muster” (gather) in case of emergencies. For a fire drill, all scientists are to carry their life vest and survival suit and muster in the lounge directly across from my stateroom. Life vests and survival suits are kept in the staterooms, so we are to grab those and get to the lounge as quickly as possible.

Fire drill

The fire drill began while the day watch was in the wet lab, one level below my stateroom. The scenario was that there was a “fire” on the 01 deck beside the lounge. That was right where my stateroom and the lounge were! Since we couldn’t get to our staterooms to gather our survival suits and life vests or muster in the lounge, due to the “fire,” we grabbed extra life vests and suits from the wet lab and mustered in the mess hall, which is near the wet lab.

Once everyone was accounted for during the fire drill, we moved out to the back deck of the ship for our Abandon Ship drill. Each person on board was assigned a life boat, and that is where we mustered for the Abandon Ship drill. First, we put on our life vests and made sure they were secured tightly. Next, we took off the life vests and put on our survival suits, which are often called “Gumby Suits” because they are large and look a lot like the animated Gumby character from the 1960′s. The survival suit is bright orange and is made out of neoprene. This makes the suit waterproof and very warm. The zipper and face flap are designed to keep water out, as well. Other features of the suits include reflective tape for greater visibility in the ocean, a whi8stle, a water-activated strobe light, a buddy line to attach to others, and an inflatable bladder behind the head to lift one’s head out of the water.

In my ‘Gumby’ suit

Boots and mittens are attached so that all one has to do is jump into the suit and zip it up. It’s not that easy, however. The arm cuffs are very tight, so it takes some strength to push your hands through. It also takes strength to pull the zipper all the way up to the center of your face. All personnel aboard the ship must be able to put this suit on and abandon ship in one minute. I was able to put my suit on in the allotted time, but we didn’t have to abandon the ship during the drill.

My stateroom

Personal Log

Living on a ship is an interesting experience. Space is at a premium, but the Henry B. Bigelow is actually quite comfortable. The scientists told me that this ship has a lot more amenities than some of the other research ships. My stateroom is small and narrow, but roommates are normally working on separate watches, so no one feels cramped or without personal space. You can see in this photo that the room has two bunk beds. Mine is on top, and it has been a fun challenge trying to get in and out of bed when the ship is rocking! I haven’t fallen yet! Each bunk has a curtain that can be pulled closed to darken your sleeping area, if you are sleeping during daylight hours. There is also a desk with latched drawers, so they don’t fly open when the ship is in rough waters. Bungee cords are attached to the walls and desks to hold chairs and large items in place, too. It’s important to keep everything tied down and in the locker so it doesn’t role around and get damaged, or make noise. I learned the importance of that my first night on rough seas when hangers were banging in my locker.

The Head

My stateroom also has its own “head” (bathroom). The term “head” comes from long ago when boats were powered by the wind. Sailors had a grated area at the front or “bow” of the boat where they could use the bathroom. It was at the front of the boat so bad odors would blow away from the rest of the ship. The figurehead was also attached at the front, so it became common practice to refer to that area as the “head.” The head in my room has a toilet that flushes, and is much nicer than the heads of days gone by, thank goodness!

These are all great amenities, but the best part of my stateroom is the view! First thing every morning, I pull back the curtain to see what’s going on outside. One morning I saw several dolphins jumping out of the water as they moved swiftly toward our ship. Most days, I’ve seen fog, rain, and roiling waves, but I still enjoy looking out and seeing nothing but water as far as the eye can see, and sometimes, a beautiful sunset.

I met my roommate, Claudia, this morning. She was on this cruise last year. Basically we catch, tag and release sharks and any other fish we may catch. I walked into town to pick up things I forgot. Ashley, Guy and I run into town for our last meal on land, a Subway. During the excitement of casting off, I’m informed that I have the night shift. Me, the goddess of the morning. they must be kidding. As we reach open water the sea is really rough.

At dinner I’m advised to go to bed right after dinner and get up at 2:00am to acclimate my body to the night shift. So right after (6:30pm) dinner I head off to bed. My roommate is already there, she is green. She tells me she doesn’t feel well and needs to lie down. There is no way I can fall asleep. I lie there, waiting to fall asleep. Finally, I’ve been lying there so long, it most be time to get up. I look at my watch… its only 9:00. I finally fall asleep.

Science and Technology Log
The last few days I have spent some time up on the bridge of the Ka’imimoana. Ensign Linh Nguyen, one of the NOAA Corps officers, showed me around and explained some of the equipment. They have three general types of equipment available on the bridge which I will categorize as: communication, propulsion, and navigation.

The bridge of the KA

The communications system first includes intra-ship lines. These are mostly carried out by an intercom type system. Each major area of the ship (including each stateroom) is connected to this intercom system by a phone that permits communication with any other part of the ship. The ship also has numerous hand-held radios available for use when one is not near a phone. In addition, the bridge has both inter-ship and ship-land communication capabilities. The KA (short for Ka’imimoana – Hawaiian for Ocean Seeker) also has access to the Iridium satellite platform for communication with land in addition to access to a satellite internet and internet VOIP system.

Autopilot and propulsion controls

There are two types of propulsion on the ship. First, there are four large diesel engines that power a generator. This generator produces the electrical power that runs each of the two electric motors that drives the screws (propellers) located at the stern (rear) of the vessel. While moving through the harbor all four diesel engines are running sending power to the generators. When the ship is out at sea only three of the diesel engines are used. The ship can operate with only two engines in service for power generation but under this configuration the ship will cruise at slower speeds. The KA has two screws: port (the left side of the ship if one is facing the bow or front of the ship) and starboard (the right side of the ship if one facing the bow). Each screw runs independent from the other with separate controls on the bridge. The conning officer (the officer who is in charge of the bridge at any given time) can change course by turning the rudder (the most common way) or by altering the speed (rpm) of one of the screws (without using the rudder). The KA also has a bow thruster (also powered by an electric motor) that is mounted in a tunnel through the forward part of the hull. This thruster permits the conning officer to move the forward part of the ship port or starboard without the main screws driving the ship forward. The bow thruster allows more subtle and precise motion that could be used for docking or perhaps helping keep the ship over a precise location while collecting data at those particular coordinates.

The bow thruster control

AIS screen

The fathometer

The captain of the KA, LCDR (Lieutenant Commander) Matthew Wingate, described the navigation system of the KA as modern but not state-of-the-art. The ship has many redundancies built into its guidance system. Two radar consoles, three compasses (two digital/electronic and one analog), an AIS (Automatic Identification System), paper charts, a fathometer (sonar) and of course, binoculars and the naked eyes of those on constant watch. The radar system is quite fascinating. It has an adjustable range with the ability to scan out to almost 100 nautical miles. The system plots the projected course of the ship and the predicted course of other ships within its range using vector analysis. This information is necessary to be able to prevent (well ahead of time) any possible collisions that might take place if the ships hold to their current courses. In addition, it is possible to set a radar alarm range of a particular radius around the ship. If any object comes within that range an alarm sounds to alert the pilot of the danger.

Radar screen

Radar tower

While I was on the bridge there were three other ships registering on the radar monitor each traveling in different directions. The two digital compasses are mounted side-by-side and their readings (and the difference between the readings) are projected at the navigation console. Above one’s head and not far from the digital compass readout is also a standard magnetic compass. The AIS (Automatic Identification System) is probably the most fascinating device I have seen on this ship. It is similar to radar readouts but provides much more information. First, one needs to understand that when ships are at sea they continuously send out a signal that provides identification information. The AIS receives this information and plots the locations and courses for these ships in addition to the location and course of the KA. All of this information is superimposed on a digital nautical chart that shows islands, shoals, exposed rocks, depth contours, and continental shorelines that can be adjusted for different scales. At the right margin of the AIS screen is listed navigation information such as the latitude and longitude of the ship, course bearing, ship speed in knots, and other pertinent data. Besides the course plotted on the AIS the conning officer also plots out the ship’s course on a paper chart and cross-checks it with the AIS. The fathometer shows the depth of the water under the ship and therefore the contours of the ocean bottom. This information can also be cross-checked with the charts and the AIS to make sure that they all agree. Last of all there is always someone on the bridge keeping watch on the instruments and the horizon verifying what is on the charts and monitors with what they see with their eyes through the binoculars.

Digital compasses

Personal Log

I have enjoyed walking about the ship during the day taking pictures and looking at the various types of equipment on the decks. I hope to describe these in later logs. I was on one of the lower weather decks this morning simply taking in the views of endless water in all directions. When the sun is out the water has a deep blue color with a very slight greenish tint. As the bow cuts through the water, waves and foam are pushed out creating a variety of tints of blues, greens, and white. It is beautiful indeed.
While I was watching, out popped a flying fish! It jumped out near the bow wave and glided about a foot off of the water for about 50 yards or more. When it would hit a wave crest it would boost itself with its tail and go a little farther. I stayed at that location for another half hour and watched many others, some small groups, and several large schools of 50 or more “fly” at one time. The longest “flight” was about 100 yards with the fish in the air maybe 5– 10 seconds. I would not have even thought to look for one of these fish. Like most children I had read about them and seen pictures of them when I was younger but never really thought that I would ever see one. What a great surprise.

Pacific Ocean and clouds

Being from Idaho’s northern latitudes, the sun only gets approximately 67Ε above the horizon on the Vernal equinox. It has been interesting to have the sun literally directly overhead during a portion of the day. This, of course, produces few areas of shadow to get out of the sun’s harsh equatorial rays. When we left San Diego it was in the mid to lower 60’s but as we have worked or way south (about 200-250 miles per day) the temperature has been slowly rising. I am told that it will soon be very hot and humid so I should enjoy this mild weather while I can.

New Terms

I have learned a few new terms for parts of the ship that might be helpful for future logs. Deck – refers to any floor on the ship. I would refer to the floor of my stateroom as the deck. Bulkhead – this refers to any walls on the ship. I am required to keep the deck and bulkheads of my stateroom clean. Head – this refers to a bathroom on the ship. I have a head that I share with a crew member in the stateroom next to me and there is also a “public” head available on this same level. Aft – can mean in back of, behind, or toward the stern of the ship. Forward (sometimes simply fore) – can mean in front of, in front, or toward the bow of the ship.

Science and Technology Log

Hello, my name is Anne Marie Wotkyns and I am participating in the NOAA Teacher at Sea program. I teach 4th grade at J.B. Monlux Magnet School in North Hollywood, California. I joined the NOAA ship Pisces on the evening of July 6 to begin a 6 day cruise in the Gulf of Mexico. I will be posting logs to share the information I learn and the experience of working aboard a scientific research vessel. We will be working on the SEAMAP Reef Fish Survey of Offshore Banks, a project which provides information about the relative abundance of fish species associated with geographic features such as banks and ledges on the continental shelf of the Gulf of Mexico. I’ll be explaining this project more in my next log entry.

Me in front of the Pisces

After meeting the other Teacher at Sea, Liz Warren and bird expert Scott Mills, at the Gulfport Mississippi Airport, we were driven to the NOAA docks in Pascagoula, Mississippi. It was quite late when we boarded the Pisces, so we found the cabin Liz and I would share, explored the ship a bit, and turned in for the night.

Wednesday, July 7 found us eager to get started on our TAS adventure. We started the day at the NOAA office and lab building, adjacent to the ship docks. There we met Kevin Rademacher, Chief Scientist for the SEAMAP (Southeast Area Monitoring and Assessment Program) offshore reef fish survey which we will be participating in on our cruise. He showed us around the NOAA facilities, which house the Southeast Marine Fisheries Offices, Seafood Inspection, and Documentation Approval and Supply Services. The fisheries division deals with resources surveys, harvesting, and engineering related to commercial fishing. The seafood inspection division deals with issues related to seafood safety and chemical and microbiological analysis of seafood. These labs can help determine if the “red snapper” your favorite restaurant serves is really red snapper or a different type of fish! This division will also be testing some of the fish we collect on our cruise for baseline data on fish from areas outside the oil spill for possible later comparison to fish collected within the spill zone.

Now a little more about the Pisces, my home away from home for the next 6 days. The Pisces was commissioned in 2009 and is one of NOAA’s newest ships. She is 63.8 meters (209 feet) long, 15 meters (49.2 feet) wide, and has a draft of 6 meters (19.4 feet.) Her cruising speed is 14.5 knots and she can stay out to sea for 40 days if necessary. On this cruise there are 22 crew comprised of a commanding officer, deck officers, engineering officers, deck hands, engineers, stewards, and survey and electronic technicians. There are 6 on our science team and 2 bird observers conducting surveys of pelagic seabirds possibly affected by the oil spill.

NOAA Ship Pisces

After we set sail on Tuesday afternoon, we spent much of the late afternoon up on the flying bridge, the highest deck on the ship. We observed a wide variety of boats and ships in the channels around Pascagoula Bay. Scott and Ron, the bird observers, helped us identify the bird species we saw, including Brown Pelicans, Laughing Gulls, and Sandwich Terns. We also saw several Atlantic Bottlenose Dolphin swimming near the ship. Soon the seas grew rougher and after dinner and a short welcome meeting, we retired to our cabins for the night.

Wednesday morning brought calmer seas, and the start of “science “ on board the Pisces. Before we reached the areas selected for the SEAMAP fish surveys, Chief Scientist Kevin Rademacher wanted to conduct bathymetric mapping of an area called Sackett Bank, off the coast of Lousiana. This involves sailing the ship in a series of overlapping transects 1.6 miles long, .05 miles apart, similar to “mowing your lawn” at home. The ME70 multibeam acoustic system covers a swath of 120 degrees using 27 beams which can detect and map features on the sea floor down to .5 meters in size. This will allow NOAA to produce highly accurate nautical charts of the region. The charts will eventually be available to commercial and sport fishermen, sailors, shipping companies, and anyone else who is interested.

Mapping Sackett Bank

When a ship is conducting activities like this bathymetric mapping or other “Restricted Mobility and Manuevers” work, they hoist a nylon “Ball-Diamond-Ball” to notify other ships in the area that it is restricted in its movement so the other ships can change their course. This message is also sent electronically by VHF radio signal. I happened to be on the bridge while they prepared to start the first transect, so Commanding Officer (CO) Jeremy Adams let me hoist the ball-diamond-ball.

Tomorrow the plans are to begin the SEAMAP reef fish surveys, “one hour after sunrise” – looks like we’ll be working from about 7 am to 7 pm with the fish! Bring it on!!

Personal Log

After submitting Teacher at Sea applications for 3 years (the first 2 years I was not selected) I am thrilled to be here! The opportunity to participate in a cruise like this on such an amazing ship is truly a once in a lifetime experience!

Here are a few more pictures of life aboard the Pisces.

Our cabin is a little small, but very clean and functional. Liz volunteered to take the top bunk, so I have the bottom. I love the little curtains that can enclose the bunk – makes a dark little “cave” for me! And the reading lamp lets me read late at night! We have a flatscreen TV, but so far we have only been able to watch the USA network – one channel only. But we don’t spend much time in the cabin anyway. The bathroom is very similar to a cruise ship bathroom, and the shower has great water pressure – however the ship is under water conservation so showers need to be quick. Notice we’re eating on paper plates with plastic utensils. No dishwashing either! After the ship moves farther from the oil spill they will able to use their salt water to fresh water conversion process and we’ll be able to use water more freely.

Pascy chooses his dinner in the “mess” – sorry – no fish!

In Pascagoula I purchased a small stuffed penguin and named him “Pascy” (for Pasacagoula.) Pascy has been exploring the Pisces so here are some shots of him around the ship!

Pascy helps check off each transect in the acoustics lab.

A little coffee is always good in the morning.

The cookies here are great!

Another big event today was the fire drill and abandon ship drill. We were assigned “muster stations”, places we would go to in event of an emergency. Part of the drill was to practice donning our “survival suits” – one piece insulated buoyant suits that would keep us afloat and warm if we ever had to abandon ship. The hardest part of the drill was getting the awkward suit on and off – they seem to be one-size-fits all and I seem to be smaller than most sailors!

Even Pascy got to participate in the drill! I don’t think he need to worry about staying afloat or warm in the water! Good thing, because that lifejacket looks a little big!

Me in Front of the Southwest Fisheries Building

Yesterday, Anne-Marie and I were given a tour of the NOAA facilities in Pascagoula. In the new building they house several different divisions; Southeast Marine Fisheries Unit, Seafood Inspection and Documentation and Approval Center. Kevin Rademacher our Chief Scientist showed us around. The labs in the Marine Fisheries unit take what is being done on the vessels and use it for research. They run many different types of research on the ships. Beside the Pisces, there are two other ships that are run out of Pascagoula; Oregon II,  and The Gordan Gunter.

Seafood Inspection Lab

On one of the floors were the Seafood Inspection labs. They bring in fish from different areas and test it. In one lab they had a set of partitions up which were the tasting areas. An example of what they have done in the past that Kevin gave us was a restaurant bought some red snapper. They brought it to the lab where they cooked in clear Pyrex containers then they smelled, checked the consistency, and tasted the fish. They discovered that the fish was not really snapper! Right now due to the oil spill they are mainly focusing on the fish that we bring in on our survey. We are required to save 10 fish out of every trap we bring up so that they can have a baseline testing of fish from an area before being it has been impacted by the oil spill.

Another floor of the building is the science labs. We walked through the plankton lab, where each person had their own station with a computer and a high powered microscope. They had several different samples out that were labeled. Just like our trip in the 6th grade they used  nets with different size holes to catch different types of plankton. Another lab was called the Age and Growth lab. Here is a picture of shark vertebrae they were preparing for aging.

Plankton lab

Today we are not working on the Reef Fish survey. Our Chief Scientist Kevin Radechamer wanted to do some mapping of an area called Sackett Bank which is south of Louisiana. The mapping they had done before did not give them an accurate depiction of the sea floor and now they have new technology. They are using an acoustic system called ME70. This system has 27 beams that run in a 120 degree swath. With the technology they had before they were only able to see 1 meter “bumps” on the surface now they can see to within a ½ meter. The white line that you can barely see shows the surface of the seafloor. The red is sand or mud that is on the bottom, as the red gets thinner and darker it is showing the harder rock that is below. As the sound waves go down they bounce back and we are able to see any see critters that are down there. Most of what you can see in the picture is plankton but occasionally you can see fish as well. This is a before and after shot of the two types of mapping. In one the map technology was guessing what was in between the bands. This information will give scientists new information about the seafloor.

Sailing Board

I’m finally here! The last two days were very exciting. When we got to the ship it was 7:00ish and most of the ship’s crew were out and about, so we had the ship to ourselves. We wandered around taking pictures and investigating. I only went on an “adventure” (lost my way) twice. Everywhere you turn there is a doorway, hatch or stairwell. I was awed by the amount of technology that they have on board. There are computer labs on almost every floor. I am envious of the color printer! Ann Marie and I are sharing a state room. It’s fantastic! The crew takes pride in what they do and it is very obvious, our beds even had mints on them. We have a T.V. and an internet connection in our room. I don’t plan on spending a lot of time in there but it is pretty fabulous!

My Stateroom

We left port yesterday and headed south. The scientists and teachers stayed on the fly deck as we moved closer to the Gulf. As we were leaving you could see what impact the oil spill has had on the Mississippi Coast and on the Barrier Islands.

Impact of Deepwater Horizon

As a result of the tropical storm over the weekend there were some pretty high swells. We had waves from 6 to 8 ft. The ship was rocking pretty badly. After our Safety Meeting where we were told about all of the safety precautions and the rules. No matter where you go there are rules. Including.. No wearing tank tops to the galley and NO sitting in the captains chair.  After the safety meeting the rolling was beginning to get to us so Anne Marie and I took to our bunks. I didn’t get sick! I did however go to sleep at 7:30.

Today we have spent most of the day wandering around the ship and talking to the many different crew members on board. Oh.. and we had a fire drill. The fire drill was a lot like having one at school, the bell rang we walked to our area and then we sat for awhile. The next drill was much more exciting. We had an Abandon Ship Drill! We had to grab a long sleeve t-shirt, a hat, pants, our Gumby suit, and a life jacket. It was a lot of stuff to carry with us! Everyone met out on the deck and I was introduced to Chief Marine Engineer Garrett who would be in charge of getting me where I needed to be in an emergency. As a first timer I was required to get into my Gumby suit. Yes, for those of you old enough to remember they are named after Gumby and Pokey. This would definitely not be my choice of a fashionable outfit. To get into it you have to lay the suit down on the ground and climb in like a sleeping bag. Then you zip it up!

In my gumby suit

Everywhere you look in the Gulf you see oil rigs or tankers moving away or to an oil rig. We passed the disaster site this morning but we were 9 miles away so we did not see any oil or much of anything. In fact I haven’t seen oil yet, which is a good thing. The interesting thing that has come about for our trip as a result of the spill is the two bird experts, Scott and Ron. The birders were hired to look for pelagic birds, those that spend most of their lives at sea. Fish and Wildlife hired one, and the other is here for BP. They are looking to see if any pelagic birds have oil on them or if they find any dead birds. So far, in the four hour s they watched this morning they saw 11 birds. Listening to them talk has been fascinating!

Sunset

This was the sunset tonight. I’m heading in with tea in hand to try and upload the rest of my pictures. I’m ready for tomorrow! Kevin said we will start a half hour after sunrise so I’ll be up bright and early! Let’s do it! Bring on the giant fish and things for me to get dirty with!

Science and Technology Log

Where am I?
Life aboard a ship is difficult to comprehend until you have experienced it first hand. If you forget something, oh well, and you live with what you have for the duration of your leg. Planning ahead is huge for a mission to the Bering Sea! (Sound familiar students?!) Life at sea can be much slower than I think people believe it to be. On this particular type of cruise, much of the day is spent waiting, watching, and analyzing information. While everyone has their job, some of those jobs require patience and flexibility.

NOAA Ship Oscar Dyson anchored in Dutch Harbor

What happened?

Ever have that moment when a demonstration fails, the cool lab you worked so hard on doesn’t work, there’s a schedule change thrown into your day, or maybe that special dinner you were planning didn’t taste right? It happens on the boat too! You have to be prepared and understand that it is going to happen. Equipment failure, human error; they all happen on board. I arrived in Dutch Harbor on June 26th and we were scheduled for departure on June 27th. There was a broken crank shaft in one of the large generators so our departure from Dutch Harbor was an educated guess at best. Without the generator, we would be in short supply of fresh water for a ship holding 39 people until July 16th. There wasn’t anything that we could do so we took advantage of being in Dutch Harbor for a couple of extra days until we departed on June 29th. Maybe the copper wire was cut before it reached the bottom on an XBT or there was a hole in the trawl net that needed to be mended. That part of life on board is no different than any other environment.

It’s an albatross, an orca, a tree?

Talk about patience…the mammal observers have lots of it. They are on watch constantly looking along the horizon for blowholes and other signs of mammalian life. When observations are slow, anything in the water can become exciting. Earlier this week while I was on the bridge, the mammal observers called down from their observation deck to the bridge because there was an object in the water that we were getting closer to. You could feel the excitement from everyone growing as this magnificent object grew closer. We got our cameras ready because this could be “the” picture of the trip and positioned ourselves to take the shot of our lives. As we approached this rather large piece of unidentified matter, we realized that it was a piece of driftwood with murres hanging out on it. At this point, the adrenaline rushed out of me and laughter took over. None of us could believe how excited we became and how let down we were to find out it wasn’t a mammal at all. Back to the observation deck!

Looking toward the horizon through the “Big Eye”

You can’t force the fish!

My primary job on this boat is to help with the fish surveying. Using the acoustics helps decide when the trawl nets are deployed for fishing. In order for fishing to occur there needs to be at least 2-3 miles of pollock showing up on the transducer screens. Weather also plays a role on what we see on the transducers. We have been very pleased with the weather so far; although it has been foggy, that usually means calmer seas. Later in the week, the weather is supposed to get dicey. When this happens there is a chance that it will be too rough to fish even if we do see the pollock. Look for my journal on weather after the weekend! Since the start of our journey we have fished three times during my shift and deployed the Methot a few times. When we are not fishing we find other things to keep us busy. Some people are analyzing data, checking equipment, or if you are a teacher at sea, you may be documenting all of your experiences. I have never taken so many pictures! The down time gives me a chance to talk to others on the boat to see what other operations are happening. As my friends and family know, I have a hard time sitting still. This is the perfect place for me to be because I have no choice but to slow my pace! It’s REALLY hard, but I think I am doing a pretty good job!

What shift are you working?

Aside from the flexibility needed to work on the ship, you also need to be flexible and patient just to live on board. Remember, you can’t just leave the ship when you need a break! The boat runs 24/7 so there are lots of shifts on the boat. To give you an idea you may be on watch for 4 hours in the dead of the night, or you may be observing mammals from sunrise to sunset. I was lucky to land the 12 hour shift from 0400-1600, but the other fisheries crew comes on for the remaining 12 hours of the day. I say this because with a full crew of 39 people on board and with everyone working different shifts, there is etiquette on board a vessel. If you and your roommate do not have the same shift, it is the unwritten rule not to enter the room while they are sleeping. That means you need to take everything with you for that shift. Not everyone eats during the allotted times that the mess hall is open so food is often set aside so everyone can have their meals regardless of what shift they work. Taking showers need to be short because everyone would like to take a hot shower after 12 hours of working. Appropriate volume is important because there may be people sleeping in the stateroom next to you and you don’t want to wake them while they are trying to sleep when off shift (remember inside voices!). It makes you very aware of your surroundings. I absolutely lucked out because Rebecca (the other TAS) and I have the same shift and same schedule. We have it much easier than most people on the boat that have opposite shifts.

Can anybody hear me?

Need time away from the hustle and bustle of life back on land? Need to take a break from your TV, cell phone, blackberry, I phone, and the internet…the Bering Sea is the place for you! Even though there is a phone on board that allows you to call off the ship, it is extremely expensive so it is definitely not for everyday use. Phones don’t work here so you can save the batteries in your cell phone or I phone for home. Most of them actually don’t even work on Dutch Harbor either. As far as the internet is concerned, that’s a little trickier. As you may have noticed, my journals took a while to be posted. It is very difficult to send information via internet from the Oscar Dyson. If we are traveling on a northern transect, we may not get internet the entire time. The transect itself could take 2 days to complete running at 12 knots! If we are turning or heading south, we may get lucky for a while. Therefore it takes time to get all the information and pictures sent just to be posted. It is very hard to be patient because I want everyone to know what’s happening and all the cool things we have been doing. Internet is sporadic at best, but keep the emails coming! It is nice to hear from everyone back home!

On board the Oregon II in the Port of Galveston

I arrived in the Port of Galveston last night in the rain on the edge of Hurricane Alex, which was making landfall farther south along the Gulf Coast. The boat was quiet. I found my quarters – Stateroom 4, below deck – which I am sharing with Walter, the Second Cook for our cruise.

Stateroom 4

We were supposed to set sail today, but given the wind and rain that Alex brought to the Gulf our departure is delayed until tomorrow. Today is a wait-out-the-weather day.

Kim (the other Teacher at Sea the Oregon II) and I are meeting the officers and the crew and scientists and learning about our work for the next two weeks. I’ll be working the “day” shift – noon to midnight – while Kim will be on nights.

We set out tomorrow, heading south along the coast. Heavy seas are expected in the aftermath of Alex, which will be a major test for my sea legs. You can follow the Oregon II’s progress here.

Pinging and Playing

We continue to “kill dots” as we work our way around the island of Farallon de Mendinilla. The mapping here will be finished tonight and then we will head north to map the seafloor of a few seamounts and banks. Most of the recent questions on this blog have been about “killing dots,” as we edit the data from the multibeam sonar. I will tell you more about the map making process in a future post. Today I want to show you some of the fun things we do aboard ship.Fishing is everyone’s favorite activity, either for the catching or the eating. The best method is trolling using lures when the ship is traveling at about 10 knots. This only happens when the ship is heading from one study area to another. When using the multibeam, the ship travels at about 4.5 knots and the fish are less apt to bite a slowly moving lure.

Frances with mahi mahi skins she is drying to make a fishing lure. Before drying she had to remove all the meat and later all the scales were removed. The resulting skin is very tough.

Jonathan on the exercise bike pedaling to Rota. There is an exercise room on the ship with a treadmill, rowing machine and weights. Many of the crew members like the bike best because it’s out on the deck with the great view.

A few of the movies available.

Movies are popular during breaks. The ship has about 800 tapes including older movies and recent releases. Many of the crew members have personal collections as well.

The desk in my stateroom.

Each stateroom (bunkroom) has a monitor so the movies can be watched in the movie room, the lounge or the staterooms. The T.V. in the lounge also gets Fox News via satellite. The internet is a popular pastime. That also comes via satellite. The ship pays a set fee for the satellite service and there is no charge to us. There are three computers in the lounge available for everyone to use. There are internet connections on the bridge, in the science labs and in the bunk rooms for people with laptops. The library has a nice collection of books and board games so there is always something to do during non-working hours.

Bellow: That’s me looking for whales. These binoculars are called “big eyes.” They are used on trips when scientists are studying mammal populations. Using these binoculars from the highest point on the ship increases the likelihood of seasickness.

Here we are splicing lines to hold buoys. There have also been several knot-tying sessions.
