Personal Log

Hello, from the Badger State! My name is Lynn Schultz-Kurth. I am a 7th and 8th grade science teacher at Prairie River Middle School in Merrill, WI, a small town in the center of the state. Summer is an exciting time here in Wisconsin, but even more exciting this year as we survived one of the nastiest winters on record. As the rivers are finally warm enough to comfortably swim in and the black-eyed susans are in full bloom, I am going to be leaving my home on the Wisconsin River for Pascagoula, MS to be part of NOAA’s (National Oceanic Atmospheric Administration) Teacher at Sea program.

I am honored to be joining the crew aboard the Oregon II, a 170ft. national marine fishing vessel, for a Shark/Red Snapper longline survey, departing from Pascagoula, MS on July 26th and returning to port in Mayport, FL on August 9th. During my mission sharks will be caught, measured, tagged, and released in order to assess their abundance, distribution, and migrational patterns, and to examine their distribution with regard to oceanographic features. I had some experience aboard a research vessel in the summer of 2011, when I participated in Sea Grant’s week long workshop for teachers aboard the R/V Lake Guardian on Lake Superior. Based on that experience, I am expecting to learn a lot, meet amazing people, work long hours and have the experience of a lifetime that will enable me to share “real” science with my students now and in the years to come.

Science and Technology Log:

Shortly after boarding the Oregon II, the science crew had orientation with the Operations Officer LTJG Thomas reviewing  basic procedures for emergencies on board. But what stuck out for me the most, was when Operations Officer LTJG Thomas said we were on a S.A.D. boat. It turns out that S.A.D. means no sex, alcohol or drugs are allowed on the Oregon II. This ensures that the boat is safe and reduces the number of accidents on board. This is the opposite of SAD and makes me feel much safer on board. But luckily for KISS fans, rock and roll is still allowed and is on consistently. Sometimes there’s so much rocking and rolling that I fall on the floor, but that’s happening less frequently as I’ve found my sea legs.

In the Groundfish Survey, after the organisms are separated by species, they are sexed. Overall, this gives the scientists an idea of what future generations will look like. Although all the organisms vary in the way you differentiate their gender, the following are some of the most common organisms found in the groundfish survey.

Sexing Shrimp

Brown Shrimp Female (top) Male (bottom)

Paneaus Aztecas Shrimp Female (top) Male (bottom)

As shown in the pictures on the left, male shrimp have a set of claspers (they look like an extra set of legs) called the petasma that is the equivalent of a penis. Females do not have a petasma.

In young (juvenile) shrimp, it can be difficult to identify the males from females as the petasma is very small and not easily visible. At this age they can easily be confused for females. When this is suspected, they are input into the computer as unknown so as not to generate inaccurate data.

Sexing Crabs

When you pick up a crab you have to be very careful to stay away their claws (cheliped). I have found that they like to grab onto you as soon as you pick them up. My roommate had a large blue crab grab her finger that would not let go and she still has bruises from it.

Shame Faced Crab

Shame Faced Crab

Mature female crabs are called a “Sook” and have a dome or bell shaped abdomen.  This is shown in the top row and looks like the U.S. Capitol Building.

Male crabs are called a “Jimmy” and have a T-shaped abdomen that looks like the shape of the Washington Monument.

To mate, the male crab will carry the female until her shell softens and she is able to mate. During mating, the female stores the males sperm to fertilize her eggs later. Once her shell hardens, the male releases her and she will fertilize her eggs later.

Female Lesser Blue Crab with eggs

After fertilization, the eggs are stored outside the female’s abdominal area and look like a sponge. They’re very squishy when you touch them. Although this shows orange eggs, they can also be a gray or black color. I have been told that the darker the egg color, the closer to hatching the offspring are. I am not sure that this is scientifically valid and am still trying to verify this.

 

 

 

Sexing Flatfish

Flatfish include fish such as flounder, halibut and turbot. These fish begin their life swimming vertically in the water. However, as they get older they sink to the bottom and their eyes move to one side of their body. They then spend the rest of their life on the bottom of the ocean floor. Luckily their top half matches the ocean floor and they are easily camouflaged from predators. The bottom half of the flounder on the ocean floor is clear or white.

The easiest way to sex a flatfish is to hold them up to a bright light. When doing this you will see that the female has a long curved gonad while the male does not.

A Confused Flounder

This Flounder is very confused. He should be a clear or light white on the bottom but as you can see his bottom half matches his top half. This could be due to a mutation but no one on the boat is exactly sure why he looks this way. This is one of the most interesting things I have seen so far. In fact, no one on the boat had seen this before.

 

 

 

 

Sea Jellies

Sea Jellies

Sea Jellies

Sea Jellies differ from most of the other marine organisms discussed so far. Sea jellies reproduce both sexually and asexually depending on what stage of life they are in. In an early stage of life sea jellies are called a polyp and they attach to a rock. The polyps reproduce asexually by cloning themselves and breaking off (budding). Imagine 300 people that came from you and look exactly like you. It’s actually pretty creepy.  But back to the sea jellies. Eventually the sea jelly will develop into an adult (medusa) that reproduces sexually with sperm and egg.

 

Personal Log:

I have a three day backpacking trip to Mt. Silliman scheduled almost immediately after my NOAA trip is over. Under normal circumstances I wouldn’t worry, but after spending two weeks not hiking or training, I’m a little concerned. Luckily there are weights and a rowing and elliptical machine on board, so I have been able to do a bit of training. Being on a ship that’s moving has made working out even more intense. I have to stabilize every time the boat moves, so I don’t fall over. But even if I did, or have, how could I complain with this view.

Holland McCandless-Lamier

Holland is my roommate on the Oregon II and is a member of the scientific party. She was contracted by Riverside in response to the Deep Water Horizon (BP) blowout in 2010. She attended the University of Mississippi and majored in marine biology. During college, Holland had an internship in Florida where she led students (from 4th grade to college) in marine science activities. This included snorkeling, visiting coral reefs and other hands on activities.

After college, Holland met an individual from the NOAA Corps at a job fair. They put her in touch with NOAA FIsheries MSLabs Groundfish Unit, where she began volunteering as a participant on surveys. This hands on experience led to her current job. Holland currently spends most of her time in the NOAA South East Fishery Science Center (SEFSC) Pascagoula lab where she works with plankton. Her current project is updating decapod (crustacean) taxonomy.

Science and Technology Log: Bottom Trawling

The Oregon II is a participant and contributor to SEAMAP (The Southeast Area Monitoring and Assessment Program) which monitors the biodiversity of marine life in the Gulf of Mexico. The primary way the Oregon II assists SEAMAP is by conducting bottom trawls with a 42 foot semi-balloon shrimp trawl net.The net is slowly lowered into the ocean until it reaches the bottom and is then dragged along the ocean floor for thirty minutes. The net has a tickler chain between the doors which scrapes the bottom of the ocean floor and flicks objects into the net. The net is then brought to the surface and all of the organisms inside are put into baskets (see video above). The total weight of the catch is massed on scales on the deck. If the catch is large (over 20 kilos), it is dumped onto a conveyor belt and a random sub-sample (smaller) is kept, along with any unique species while the rest of the catch is dumped overboard.

Shrimp Net

Once the sample has been selected, the marine organisms are sorted by species and put into baskets. Each species is then massed and counted while the data is recorded into a system called FSCS (Fisheries Scientific Computer System). To obtain a random sampling, every fifth individual of the species (up to twenty) is measured, massed and sexed (more on this later). Once the data has been verified by the watch manager, the marine organisms are put back into the ocean. The following are pictures of a sample on the conveyor belt and the organisms divided into a few species.

The sorting process for shrimp (white, brown and pink) differs slightly from that of the other marine organisms. Every shrimp (up to 200 of each species), is massed, measured and sexed.This data is then used by various government agencies such as the Fish and Wildlife Service, Gulf of Mexico and South Atlantic Fishery Management Councils, etc… to determine the length of the shrimping season and to set quotas on the amount that can be caught by each issued license. States will not open the shrimping season until SEAMAP reports back with their findings from NOAA’s shrimp survey.

Types of shrimp in the Gulf of Mexico

The shrimp trawl net used on the Oregon II differs from a shrimp net used on a commercial boat in two main ways. Commercial shrimping boats have BRD’s (Bycatch Reduction Devices) and TED’s (Turtle Excluder Devices). BRD’s and TED’s are federally required in the U.S. to reduce the amount of bycatch (unintentionally caught organisms) and sea turtles. Shrimping boats typically trawl for hours and turtles cannot survive that long without air. TED’s provide turtles and other large marine organisms an escape hatch so that they do not drown (see the video below). Unfortunately, larger turtles such as Loggerheads are too big to fit through the bars in a TED. Additionally, TED’s may become ineffective if they are clogged with sea debris, kelp or are purposefully altered.

     

Boat Personnel of the Week:

Warren Brown:

Warren Brown

Warren is a gear specialist who is working as a member of the scientific party. He is contracted by Riverside for NOAA.  While aboard the Oregon II, Warren designs, builds and repairs gear that is needed on the boat. Unfortunately, on this leg of the trip either sharks or dolphins have been chewing holes in the nets to eat the fish inside. This means Warren has spent a large chunk of his time repairing nets.

Warren is not a crew member of the Oregon II  and actually works at the Netshed in Pascagoula where he spends his time working with TED’s. He has law enforcement training and will go out with government agencies (such as the Coast Guard or Fish and Wildlife Service) to monitor TED’s on shrimping boats. He also participates in outreach programs educating fishermen in measuring their nets for TED’s, installing them. Warren will bring TED’s and nets to make sure that every everyone at the training has a hands on experience installing them. While he regularly does outreach in Alabama, Mississippi, Florida, Georgia, North Carolina and Texas, his work has also taken him as far as Brazil.

Robin Gropp:

Robin will be a junior at Lewis & Clark College in the Fall. He is currently an intern aboard the Oregon II. Robin received a diversity internship through the Northern Gulf Institute and is one of eight interns for NOAA. For the first two weeks Robin worked at the NOAA lab participating in outreach at elementary school science fairs. He brought sea turtle shells and a shrimp net with a TED installed. The students were very excited to pretend to be sea turtle and run through the TED. They proclaimed, “we love sea turtles.”  After leaving the Oregon II, Robin will return to the NOAA lab to study the DNA of sharks.

 

Personal Log:

Overall I have had a hard time processing and accepting the groundfish survey portion of the trip. I am a vegetarian that does not eat meat, including fish, for ethical and environmental reasons. Yet here I find myself on a boat in the Gulf of Mexico surveying groundfish so that others can eat shrimp. A large part of me feels that I should be protesting the survey rather than assisting. Because of this I spent a lot of time talking to the other scientists on my watch and Chief Scientist Andre Debose. After many discussions (some still ongoing) I do realize how important the groundfish survey is. Without it, there would be no limits placed on the fishing industry and it is likely that many populations of marine organisms would be hunted to extinction more rapidly than they are now. This survey actually gives the shrimp species a chance at survival.

Did You Know?

Countries that do not use TED’s are banned from selling their shrimp to the U.S.

Getting ready to lower the CTD

Getting ready to lower the CTD

CTD with Niskin Bottles and instument panels

CTD with Niskin Bottles and instrument panels

The Oregon II carries an instrument called a CTD (Conductivity, Temperature, Depth) that is lowered into the ocean by a crane. On the bottom of the CTD are sensors that detect and relay information back to a computer onboard the Oregon II. On top of the sensors are Niskin (gray) bottles that are manually opened before the CTD is lowered into the water, and are tripped by the Watchleader (closing and trapping water inside) when it reaches the desired depth. Data from the CTD is sent to the ship where it is recorded and stored. After the CTD is back on board, the water from the Niskin bottles is used to check the amount of dissolved oxygen. This data is then combined with numerous stations/stops and used to create a real time map of the dissolved oxygen levels in the Gulf of Mexico.

 

Real Time Dissolved Oxygen Map from the Oregon II

Real Time Dissolved Oxygen Map from the Oregon II

One of the missions of the SEAMAP cruise is to measure the amount of dissolved oxygen (DO) in the Gulf of Mexico. Dissolved oxygen is the amount of oxygen that is present in the water and is available for marine life. When the dissolved oxygen content drops below 2mg/L, the water is considered to be hypoxic and the area may be called a dead zone. Basically, what this means is that marine life cannot survive because they do not have enough oxygen.

If you can imagine living at the top of Mt. Everest without an oxygen tank, that is what living in hypoxia would be like to a fish.  While the majority of organisms cannot survive in a dead zone, those organisms that do survive have been found to have permanent changes in their reproductive systems, such as smaller ovaries and fewer eggs in female fish. Dead zones in the Gulf of Mexico are due to runoff from Nitrates and Phosphates that come from fertilizers, detergents and human/animal waste. Because of hypoxia, phosphate detergents have been banned in the Great Lakes and you may even notice that some of your household detergents say “phosphate free”.

Personal Log:

Overall I’m pretty exhausted both mentally and physically. While I have taught my Environmental Students about some of the things I am doing, it’s my first time putting these into practice myself. Although I am grateful for the experience, it is a bit much to take it all in and I feel slightly overwhelmed. Luckily, I will have the chance to perform these tasks over and over before the Oregon II returns to shore. And more importantly, I am working with an amazing team of scientists who are happy to answer all of my questions and walk me through procedures multiple times.

I’m slowly adjusting to being in a different time zone, but am definitely feeling the time change. I am on the night shift which means I start work at midnight and finish at noon. This is unusual for me since I like to be in bed by ten every night. On the bright side, my night shift means I get to beat the heat during the middle of the day when the temperatures are in the eighties.

Immersion Suit

Finally in my Survival Suit

 

Yesterday we had an emergency abandon ship drill where we had to don survival suits. You put them on as though you were getting into a sleeping bag. This meant a lot of rolling around on the floor for me, but I like to think I entertained the crew while I was doing it. My dad thinks I look like Sebastian from the Little Mermaid in my suit, but I’m confident that I will be a warm lobster until rescue arrives in the unlikely event I have to abandon ship.

 

 

Did You Know?

Male seahorses, not female seahorses, carry fertilized eggs and give birth to their young. They will also eat any of their offspring that don’t swim away quickly enough. It pays to be a female seahorse!

Science and Technology:

Collecting plankton is a very important activity for the scientists on the ship. Everyday and night they collect the very tiny plants and animals we refer to as plankton. Plankton is very important because it supplies the world with oxygen and it is the beginning of many food chains.

Plankton

This is what we collect using the bongo nets.

The bongo nets are used to collect the plankton from the water. There are two bongo drums connected together and lowered into the water. Each one has a cylinder container connected to the end of the net with holes covered with mesh so that the water can flow out, but the mesh catches the plankton.

Tiny plants and animals that drift in the ocean currents flow into the nets. When the nets are brought back onto the ship, they are rinsed so that nothing is lost. The material collected is then rinsed into sieves and into jars with preservatives. The scientists that use the plankton for research decide which preservatives will be added. Sometimes it is in ethanol and sometimes in formalin, it is up to the scientists at the lab. All of these jars are sent to the lab on land and sometimes the material may be sent to labs in Poland to be examined.

To know how far the nets need to be lowered the scientists work with the deck crew and the bridge. Everyone makes sure the nets go very deep into the water, but that the nets do not touch the bottom. If they did touch the ocean floor there is a good chance that the nets would be damaged.

They also need to monitor how much water flows through the nets while the nets are in the water. To do this there are small flow meters connected to the nets. Before the nets go into the water, the numbers on the flow meter are put into the computer. After the nets come back up the numbers are again entered into the computer. Looking at the difference between these two numbers let the scientist know how much water flowed through the nets.

Flow meter on bongo net

Here is the flow meter on the bongo net.

The main reason plankton surveys are conducted is to collect samples for estimating the number and place where fish larvae can be found.

When we are doing the CTD, we must give the weather conditions: cloud cover, height of waves, and the color of the water.

Here I am checking the sky and water.

Careers:  The people behind the scenes

The Chief Steward Walter Coghlan is a delightful person to watch in the kitchen and a lifesaver for me while I was under the weather. Walter has been with NOAA since 2008 and with his 21 years in the Navy, this Saturday, June 21st, will mark the 30th year at sea for him.

In the Navy, Walter was on various ships such as the USS Lexington and USS John F Kennedy. He even was a cook on a mine sweeper during the war. In the Navy he was a Culinary Specialist, he said that while on the USS John F Kennedy, President Ronald Reagan (everyone near Amboy and Dixon knows who that is) came aboard and asked for Walter to make fried chicken.
Walter also completed Finishing School for Chefs and for three years he served as the chef at the White House. This was when President George Bush was in office.

On the ship he has a budget of $10,000 per month to feed over thirty people three meals a day and provide snacks. His day starts around 4:30 AM and ends around 6:30 PM. He is certified as a Chief Cuisine and he is a superb chef. His future goal is to retire in one year and spend time with his family.

Chief Steward and 2nd cook

Chief Steward Walter and 2nd Cook Steve in the kitchen.

2nd Cook is Steve Daley. Steve is on his first trip on the NOAA Ship Oregon II. He is a augmenter, which means he is a sub and fills in where and when he is needed.

Steve is a Army veteran where he was a cook for eleven years. After the Army, Steve worked at the Pennsylvania Dept. of Correction where he taught culinary classes for 20 years.
Steve is also a wonderful chef and working in the small kitchen space must be difficult at times.

You can believe me when I say that eating on this ship was as good as eating at a fancy restaurant at home!

Engineers:
Sean Pfarrer is the Chief Marine Engineer on the NOAA Ship Oregon II. Due to my schedule the only time I saw Sean was when he was eating, so I was not able to interview him.

Richard Brooks

1st Engineer Richard Brooks

1st Engineer is Richard Brooks. He just joined the NOAA team on this trip and will be with NOAA for two years. Before that he was an engineer on the big oil tankers. He talked about being on the big oil tankers and pointed out the differences between them. He explained how some of the tankers are so big they can not go close to land and smaller tankers will either take fuel to them or from them. It is amazing how much information he has about the different ships.

Richard would sometimes make a trip through the wet lab after our catch to see  what we caught.

2nd Engineer is David Carlise. David was in the Coast Guard for four years. He has traveled all over the world on ships and had many stories of his adventures to share with us. After leaving the Coast Guard, David was a Commercial Fisherman for 17 years where he was the captain. He was a Merchant Marine and was the engineer for a cargo boat, tub boat, and a tanker. He will be getting off in Galveston and flying to the state of Oregon for his next assignment on another ship.

He gave Robin and I a tour of the engine room, it is very noisy and very hot down there, but amazing to see what makes the ship sail! Jerry explained how everything works down below our feet. The electrical board is huge! And seeing the crank shaft of the engine was really cool!

Wiper Otha Hill

Wiper Otha Hill

Wiper Otha Hill, also known as OC, has been with NOAA since 1984. He has worked on the ship Oregon II for 18 years and worked on four other NOAA ships. One of the ships was a weather ship in Chile! He has also worked on Union Ships in the engineering dept., built ships for four years, was a welder and a Junior Engineer and spent six years working on big ships.

As the Wiper, Otha, cleans, paints, and assists with everything that needs something done to it in the engine room area.

These are the people that have very important jobs on this ship. When the shower drain is plugged or the air conditioning goes out, everyone is looking for these men!

The other night and again today we saw Frigate birds flying near the ship. Some say that seeing this bird will bring you good luck….hope so! The Frigate (Fregata) is a seabird that can have a wingspan of over 2 meters. They are a large bird, closely related to the pelicans. For more information check out this website: http://a-z-animals.com/animals/frigatebird/

I cannot wait to share my photos and everything that I have learned. The various species of fish, that you can only tell apart by looking at that one little dot on the bottom of their body or because their eyes are closer together that the other fish (that is the same shape and color and looks just like them) or the shrimp and crabs that are so numerous it has taken me this entire trip to look over the books in the dry lab with their names and information.

Chrissy and me

My bunkmate, Chrissy and me.

Even though my bunkmate, Chrissy Stepongzi and I did not spend a lot of time together (we worked opposite shifts), I can say she was there when I was sick and has a great sense of humor. She graduated with a Major in Biology and worked as a high school sub for two years. For Chrissy the best part of this job is being on the ship and when she is on land she likes to spend time with her cat and dog.

Yes, I have picked up fish of all sizes and shapes. Yes, I can tell if they are a boy or girl. Yes, I have taken the heads off of shrimp. Yes, I have had wet feet for over ten hours everyday. AND yes, I have survived. I do miss my family, my dog (Ginger) and all the students at Central, but I would come back to this ship in a minute!

I feel so fortunate to have been selected for this and even more fortunate to have been able to sail on the NOAA Ship Oregon II with everyone. Kim Johnson went above and beyond to make sure I was involved and learning something new everyday….thanks! And Taniya, Andre, and Robin will forever make me laugh when I think back on how much time we spent together…the work, the songs, the stories, have all made lasting memories!

Mission: SEAMAP Groundfish Survey

Gulf of Mexico

June 14, 2014

Weather: Partly cloudy. Winds 10 to 15 knots. Waves 1 to 2 feet.

Science and Technology Log:

We have been very busy with stations. The catch on Thursday included a variety of shrimp.  There are many different kinds of shrimp and a lot of them can be found in the Gulf of Mexico. Did you know that most shrimp have a short lifespan, maybe only two to three years?

Some of the ones we caught were the Rose Shrimp (Parapenaeus politus), Roughback Shrimp (Rimapenaeus constrictus), Brown Rock Shrimp (Sicyonia brevirostris stimpson) and the Spiny Rock Shrimp (Sicyonia barkenroadi). Since the scientist use the proper names for each species, I am trying to learn those names too!

 

shrimp in Gulf of Mexico

Can you identify this species of shrimp?

NOAA is one of the primary agencies that watches over the aquaculture or farming in the water. With surveys such as the one the NOAA Ship Oregon II is conducting they are able to calculate the amount of fish, shrimp, and other organisms that can be taken out each year. It is similar to the hunting season we have for deer at home. This protects the industry and allows for the species to grow and not be overfished.

Red snapper is a species that was being overfished for many years and because of this they were not growing to maturity. Now with limits on how many red snapper can be caught, it is making a comeback.

Another way that the scientist collect species on the NOAA Ship Oregon II is by using the Neuston nets. These large nets float half in the water and half under the water. They are designed to collect the tiny organisms that float on the top of the water or live right under the surface of the water.

Neuston tow

Here are the Neuston nets being towed at night.

When the nets are being brought back to the ship, we must rinse everything down into the bottom collection container. The material is then placed into jars and chemicals are added to preserve everything.

Later the material collected must be transferred into other chemicals and then sent back to the lab on land to be identified.

In the photo I am helping Scientist Andre Debose prepare the samples for transfer.

 

Careers

It takes many people doing many different jobs to keep a ship like the NOAA Ship Oregon II running smoothly.
One job is the ET or Electrical Technician. The ET is a person that helps maintain and repair the electronic components and equipment or devices that use electricity. The NOAA Ship Oregon II is very fortunate to have Brian Thomas as their ET. Brian is ready to work on anything from the radar of the ship to my laptop that I am using to write my blog.

He has been with NOAA as an independent Federal worker since 2006. Before that he was in the Navy for 20 years working with sonar, so Brian knows his way around the ship! He also worked at the shipyards before joining the crew.

He said he had training for three years to learn his present job and because so much of the ship’s equipment works with electricity, Brian is on call 24 hours a day. Normally he said ships have rotating ET’s, but he is the only one on this ship.

Brian said it is a very interesting job and the best part is when everything is going well!

Internship:

NOAA has two college students doing an internship on the NOAA Ship Oregon II this season. One of them is Robin Gropp who will be a sophomore at Lewis and Clark College in the state of Oregon in the fall.

Robin is a biology major and his future goal is to be a marine scientist and maybe work with alternative energy, mainly tidal power, also called tidal energy. This is a form of hydropower that using the tides to make energy. (Kind of like how we have the wind mills that use wind near Amboy to make energy)

Robin is working for NOAA this summer to learn more about the sea turtles and study why they sometimes get stranded or caught on piers. He is also studying the sharks and rays that we might catch while on the Groundfish Survey.

The best part of being involved with a NOAA internship to Robin is the hands-on research that he is conducting.

Personal Log:

Today the Lead Fisherman, Chris alerted me to the fact that there were bottlenose dolphin swimming behind the ship. The dolphin were following the nets in hopes of snagging a free meal. I quickly grabbed my camera and headed out to watch the dolphins!

The bottlenose dolphins are the most common and well-known members of the marine family. They can live up to 50 years and can be found in temperate and tropical waters around the world. For more information, go to this link:

The dolphins were amazing to watch as they slapped the water with their tails and followed the net right up to the ship. I have included a video and a picture, but this really does not show the true beauty it was to watch them live. I am so lucky to be out here in the Gulf of Mexico aboard the NOAA Ship Oregon II.

There is such a wide variety of species living in the Gulf of Mexico. I have included some photos of just a few of the ones we have caught in the nets.

The Atlantic flying fish uses its pectoral fins to “catch” the air currents and moves it’s tail back and forth to move forward.

I am feeling much better now that we have been out to sea for seven days. Walking around on the ship can be tricky somedays, but I am getting better at it everyday!
