Personal Log
In 2011 I was honored to learn and work aboard the NOAA ship the Oscar Dyson in Alaska as a Teacher at Sea, and I can’t tell you how many people told me that it was the trip of a lifetime.  Imagine my excitement to learn that I get to return to sea as a Teacher at Sea alumni aboard the Bell M. Shimada.  The way I see it is that I get two trips of a lifetime, in one lifetime!  I feel pretty lucky.

On my first Teacher at Sea voyage, I documented my trip via a cartoon series called Adventures in a Blue World, a tribute to Sylvia Earle’s book The World is Blue.  This time I will once again do my best to bring to life my Teacher at Sea experiences via a second volume of cartoons.  You can read the introduction below on being selected as a Teacher at Sea, Hake, and the beginning of this next adventure.  (Cartoon citations 1, 2, and 3)

I have been an educator for nineteen years, and now live and work in West Texas–on the Llano Estacado–in Lubbock.  I’m a science instructional coach at Estacado High School, which basically means that I get to collaborate with teachers and students to develop great labs and activities.  It is a wonderful job, and I am looking forward to bringing back real-world research and developing curriculum for our students.

I am going to miss my family, Ike, Madalyn, and Eva.  The girls love the water (even bringing inflatable fish into the house…), and Ike has run rivers all over the Southwest, but I get to go where no family and friends are allowed–from Newport, Oregon, to Seattle, Washington on the NOAA ship the Bell M. Shimada.  They will also be following along with me remotely.

Some quick math for you: since its inception in 1990, Teachers at Sea have logged over 100,000+ hours of research on 8,200+ days at sea.  Crunching some quick numbers, this equals about 67 school years of professional development in Real Science-Real Research-and Real Experience.  Pretty nifty, eh?  See this link for more.

Until our next adventure,

When an anchor is dropped, forces in the ocean will cause this massive object to drift as it falls.  Last year, after the anchor of mooring 12 was dropped, an acoustic message was sent to the release mechanism on the anchor to locate it.  This was repeated in three locations so that the location of the anchor could be triangulated much like how an earthquake epicenter is found.  This was repeated this year for mooring 13 so next year, they will know where it is.  From where we dropped the anchor to where it fell, was a horizontal distance of 3oo meters.  The ocean moved the 9300 pound anchor 300 meters.  What a force!

The next morning as the ship was in position, another acoustic message was sent that triggered the release of the glass floats from the anchor. Not surprisingly, the floats took nearly an hour to travel up the nearly 3 miles to the surface.

Float recovery

A small boat went to retrieve the mooring attached to the floats

Once the floats were located at the surface, a small boat was deployed to secure the end of the mooring to the Hi’ialakai. The glass floats were loaded onto the ship.  17 floats that had imploded when they were deployed last year.  Listen to imploding floats recorded by the hydrophone.  Implosion.

Next, came the lengthy retrieval of the line (3000+ meters). A capstan to apply force to the line was used as the research associates and team arranged the line in the shipping boxes. The colmega and nylon retrieval lasted about 3 hours.

Bringing up the colmega line.

Bringing up the colmega line and packing it for shipping.

Once the wire portion of the mooring was reached, sensors were removed as they rose and stored. Finally the mooring was released, leaving the buoy with about 40 meters of line with sensors attached and hanging below.

The NOAA officer on the bridge maneuvered the ship close enough to the buoy so that it could be secured to the ship and eventually lifted by the crane and placed on deck. This was followed by the retrieval of the last sensors.

The following day required cleaning sensors to remove biofoul.  And the buoy was dismantled for shipment back to Woods Hole Oceanographic Institution.

Mooring removal was accomplished in seas with 5-6 feet swells at times. From my vantage point, everything seemed to go well in the recovery process. This is not always the case. Imagine what would happen, if the buoy separated from the rest of the mooring before releasing the floats and the mooring is laying on the sea floor? What would happen if the float release was not triggered and you have a mooring attached to the 8000+ pound anchor?  There are plans for when these events occur.  In both cases, a cable with a hook (or many hooks) is snaked down to try and grab the mooring line and bring it to the surface.

Now that the mooring has been recovered, the science team continues to collect data from the CTD (conductivity/temperature/depth) casts.  By the end of tomorrow, the CTDs would have collected data for approximately 25 hours.  The data from the CTDs will enable the alignment of the two moorings.



The WHOTS (Woods Hole Oceanographic Institution Hawaii Ocean Time Series Site) mooring project is led by is led by two scientists from Woods Hole Oceanographic Institution;  Al Plueddeman and Robert Weller.  Both scientists have been involved with the project since 2004.  Plueddeman led this year’s operations and next year it will be Weller.  Plueddeman recorded detailed notes of the operation that helped me fill in some blanks in my notes.  He answered my questions.  I am thankful to have been included in this project and am grateful for this experience and excited to share with my students back in Eugene, Oregon.

Al Plueddeman

Al Plueddeman, Senior Scientist

The long term observations (air-sea fluxes) collected by the moorings at Station Aloha will be used to better understand climate variability.  WHOTS is funded by NOAA and NSF and is a joint venture with University of Hawaii.  I will definitely be including real time and archived data from WHOTS in Environmental Science.

Personal Log

I have really enjoyed having the opportunity to talk with the crew of the Hi’ialakai.  There were many pathways taken to get to this point of being aboard this ship.  I learned about schools and programs that I had never even heard about.  My students will learn from this adventure of mine, that there are programs that can lead them to successful oceanic careers.

Brian Kibler

Brian Kibler

I sailed with Brian Kibler in 2013 aboard the Oscar Dyson up in the Gulf of Alaska.  He completed a two year program at Seattle Maritime Academy where he became credentialed to be an Able Bodied Seaman.  After a year as an intern aboard the Oscar Dyson, he was hired.  A few years ago he transferred to the Hi’ialakai and has now been with NOAA for 5 years.  On board, he is responsible for rigging, watch and other tasks that arise.  Brian was one of the stars of the video I made called Sharks on Deck. Watch it here.

Tyler Matta

Tyler Matta, 3rd Engineer

Tyler Matta has been sailing with NOAA for nearly a year.  He sought a hands-on engineering program and enrolled at Cal Maritime (Forbes ranked the school high due to the 95% job placement) and earned a degree in maritime engineering and was licensed as an engineer.  After sailing to the South Pacific on a 500 ft ship, he was hooked.  He was hired by NOAA at a job fair as a 3rd engineer and soon will have enough sea days to move to 2nd engineer.



There are 6 NOAA Corps members on  the Hi’ialakai.  They all went through an approximately 5 month training program at the Coast Guard Academy in New London, CT.  To apply, a candidate should have a 4 year degree in a NOAA related field such as science, math or engineering.  Our commanding officer, Liz Kretovic, attended Massachusetts Maritime Academy and majored in marine safety and environmental protection.  Other officers graduated with degrees in marine science, marine biology, and environmental studies.

ENS Chappelle

NOAA Ensign Nicki Chappelle

Ensign (ENS) Nikki Chappelle is new to the NOAA Corps.  In fact, this is her first cruise aboard the Hi’ialakai and second with NOAA.  She is shadowing ENS Bryan Stephan for on the job training.  She spent most of her schooling just south of where I teach.  I am hoping that when she visits her family in Cottage Grove, Oregon that she might make a stop at my school to talk to my students.  She graduated from Oregon State University with degrees in zoology and communication.  In the past she was a wildfire fighter, a circus worker (caring for the elephants) and a diver at Sea World.

All of the officers have 2 four hour shifts a day on the bridge.  For example ENS Chappelle’s shifts are 8am to 12pm and 8pm to 12am.  The responsibilities of the officers include navigating the ship, recording meteorological information, overseeing safety.  Officers have other tasks to complete when not on the bridge such as correcting navigational maps or safety and damage control. ENS Stephan manages the store on board as a collateral assignment.  After officers finish training they are sent to sea for 2-3 years (usually 2) and then rotate to land for 3 years and then back to sea.  NOAA Officers see the world while at sea as they support ocean and atmospheric science research.

Frank Russo

ET Frank Russo

Electronics technician (ET) seem to be in short supply with NOAA.  There are lots of job opportunities.  According to Larry Wooten (from Newport’s Marine Operation Center of the Pacific), NOAA has hired 7 ETs since November.  Frank Russo III is sailing with NOAA for the first time as an ET.  But this is definitely not his first time at sea.  He spent 24 years in the navy, 10 at Military Sealift Command supporting naval assets and marines around the world.  His responsibilities on the Hi’ialakai include maintaining navigational equipment on the bridge, making sure the radio, radar and NAVTEX (for weather alerts) are functioning properly and maintaining the server so that the scientists have computer access.

I have met so many interesting people on the Hi’ialakai.  I appreciate everyone who took the time to chat with me about their careers or anything else.  I wish I had more time so that I could get to know more of the Hi’ialakai crew.  Thanks.  Special thanks to our XO Amanda Goeller and Senior Scientist Al Plueddeman for reviewing my blog posts.  And for letting me tag along.


Did You Know?

The buoy at the top of the mooring becomes a popular hang out for organisms in the area. As we approached mooring 12, there were several red-footed boobies standing their ground. There were also plenty of barnacles and other organisms that are planktonic in some stage of their lives. Fishing line is strung across the center of the buoy to discourage visitors but some still use the buoy as a rest stop. The accumulation of organism that can lead to corrosion and malfunction of the equipment is biofoul.

Denise Harrington, Getting Ready for an Adventure, April 23, 2016

NOAA Teacher at Sea
Denise Harrington
(Almost) aboard NOAA Ship Pisces
May 04, 2016 – May 17, 2016

Greetings from Garibaldi, Oregon. My name is Denise Harrington and I teach Second Grade at South Prairie Elementary School in Tillamook, Oregon, along the north Oregon coast. There are 300 amazing second and third graders at our school who can prove to you that no matter how young you are, you can be a great scientist.  Last year they were caught on camera by Oregon Field Guide studying the diversity of life present in our ocean.


I applied to become a NOAA Teacher at Sea because I wanted to work with scientists in the field. I seem to learn best by doing.  In 2014, I joined the crew of NOAA ship Rainier, mapping the ocean floor near Kodiak Island, Alaska.  I learned how vast, connected, and undiscovered our oceans are. Students watched in disbelief after we discovered a sea floor canyon.  I learned about the technology and skills used to map the ocean floor. I learned how NOAA helps us stay safe by making accurate nautical charts.  It was, for our students and myself, a life changing experience.

As an avid sea kayaker, I was able to share my deeper understanding of the ocean with fellow paddlers. Photo courtesy of Bill Vonnegut

Now, I am fortunate enough to participate in another NOAA survey. On this survey aboard NOAA ship Pisces, scientists will be collecting data about how many fish inhabit the area along banks and ledges of the Continental Shelf of the Gulf of Mexico.
NOAA believes in the value of sharing what they do with the public, and students in particular. The crew of Pisces even let fifth grader students from Southaven, Mississippi name the ship after they won a writing contest. Maybe you can name the next NOAA ship!

On May 3, 2016, Ship Pisces will begin Leg 3 of their survey of reef fish. I have so many questions.  I asked Chief Scientist Kevin Rademacher why the many survey partners chose snapper and grouper to survey. He replied “Snapper and grouper are some of the most important commercial fisheries here in the Gulf of Mexico. There are 14 species of snapper in the Gulf of Mexico that are good to eat. Of those the most commercially important is the red snapper. It is also currently over-fished.”   When I hear “over-fished” I wonder if our second graders will have many or any red snapper to eat when they they grow up. Yikes!

Another important commercial catch is grouper.  My brother, Greg, who fishes along the Kenai River in Alaska understands why grouper is a focus of the survey. “It’s tasty,” he says. I can’t believe he finds grouper tastier than salmon.  NOAA is making sure that we know what fish we have and make sure we save some for later, so that everyone can decide which fish is the tastiest when they grow up.

I have so many questions keeping me up at night as I prepare for my adventure. What do I need to know about fish to do my job on the ship?  Will I see evidence of the largest oil spill in U.S. history, the Deepwater Horizon spill? How crowded will we all be aboard Ship Pisces? If I dissect fish, will it be gross? Will it stink?  Will I get sea sick? With my head spinning with questions, I know I am learning. Yet there is nothing more I can do now to prepare myself for all that I will learn, except to be early to the airport in Portland, Oregon, and to the ship in Pascagoula, Mississippi, on May 3rd.

I will get home in time to watch my daughter, Elizabeth, graduate from high school.  Ever since I returned from the NOAA cruise in Alaska, she has been studying marine biology and even competed in the National Ocean Sciences Bowl.

During research in the Gulf of Mexico with the crew of Ship Pisces, I will learn about the many living things in the Gulf of Mexico and about the technology they use to protect and manage commercial fisheries.  Soon, you will be able to watch me collect data about our ocean critters. Hope for fair winds and following seas as I join the crew on Ship Pisces, “working to protect, restore, and manage the use of our living ocean resources.”

Science Log

Kodiak, Alaska is amazing and NOAA Ship Rainier is even more so.  When I arrived I learned that we were going to be in port for a few days.  Instead of leaving on Tuesday, September 08, 2015 we are scheduled to leave on Saturday.  Early in my planning and training I learned that FLEXIBILITY is very important and it has proven to be true.

NOAA TAS 2015 005

Rainier with the rising sun behind it at Women’s Bay

During this time at port, the entire crew is very busy with ship activities.  I thought this would be the perfect time to give some background on this amazing ship!  Here is a link to more detailed information Rainier information flyer.  An even more detailed, “let the geek out” link is   Rainier special details.

Rainier is named after Mount Rainier in Washington State and was put to work in 1968.  Do the math, how old is Rainier this year?  Rainier is a long 231 foot ship.  The breadth (width) is 42 feet and the draft, or how far down it sits in the water is 14 feet.  One of the most interesting facts about this vessel is the ice strengthened hull.  Rainier is one tough ship!!

To keep this unique ship running so well it has an incredible crew.  I have learned that there are 7 main areas of work.  I am only going to give a general overview so everyone can understand a little bit more about what happens here.  I will go into more detail with future blogs.

Wardroom – This is what the NOAA uniformed officers are called.  They can be seen wearing their blue uniforms.  The hydrographic officers have a more interesting job than the officers on other NOAA vessels because they act not only as officers getting the ship where it needs to go safely, but they also work right alongside the survey scientists making tidal observations and coastal maps.

The Rainier Officers working in the Plotting Room

Rainier Officers working in the Plotting Room

It makes a lot of sense for the people who are researching and creating the very important coastal maps to understand them.  There is no one better than the men and women who work with them every day!

Survey – These are the scientists who work with the officers to collect the data.  Collecting the data is just the beginning.  Once the data is collected they begin analyzing data and putting it to work.  Similar to students who have classwork, they get assignments that need to be met and deadlines to get the work done.  It can take weeks and months for the data to be put together to make the charts.

Engineering – The engineers are the inner working of the ship.  They are the men and women who keep Rainier going strong!  While here, there is a constant hum of mechanical parts (later the engines will be going and we will hear and feel those).

Just one of many areas the engineers work. This is an organized machine shop for repairs/fabricating.

Just one of many areas the engineers work. This is an organized machine shop for repairs/fabricating.

Everywhere you look inside the ship you can see something that the engineers are responsible for maintaining.  On my tour, I was amazed from top to bottom of the fans, gears, plumbing, wires, generators, motors, hydraulics, engines, heating/cooling, launch maintenance, refrigeration, distillers for water plus so much more that needs to be kept going.  As you can see, this is also a very busy department!

Deck – While the engineers maintain the inside of the ship, the deck crew maintains the outside or what is called the “weather deck”.   Here you will see the massive crane on the back of the ship and two smaller cranes at the front.

The large crane at the stern (back) of the ship.

The large crane at the stern (back) of the ship.

They work the two large anchors and the “windlass” or winch to pull them up along with the smaller launches (boats) that are attached to the ship and the davits (hoists) to put them in and out of the water.  The deck crew also make sure the ship is moored (tied up) properly plus so much more.

EET and ET – These are the two smallest departments, but they are needed to keep everyone working.  The EET is the electronics engineering technician.  He is an electrician that takes care of all the wiring throughout the ship.  The Rainier EET has been here for over 20 years.  The ET is the electronics technician and he builds, maintains and programs the computers and servers that are needed to run Rainier.

Steward – Have you heard the term “laughter is the best medicine?”  Here on Rainier the food is the best medicine and what keeps this crew connected and happy!

The incredibly clean and efficient galley on the Rainier

The incredibly clean and efficient galley on Rainier

The galley (kitchen) is incredibly clean, organized and delicious!  The selection of food has been healthy, varied and with just the right amount of sweet treats.  They are up very early and work later to keep this crew fed.  Every department has to come through here so they are the true backbone of the ship!

As I get to know the ship and crew more, I am continually amazed at the people here, how they communicate and work together and it all runs so smoothly.  I am looking forward to our upcoming adventures doing research around Kodiak Island.

Personal Log

Being chosen for this experience is a great honor for me.  I was here for only 24 hours and I had already seen so much of this beautiful area.  I was fortunate enough to get here the night before Labor Day so the crew and I had the day off.

One of the harbors in Kodiak, AK

One of the harbors in Kodiak, AK

I walked around the harbor town of Kodiak and then went hiking to Abercrombie State Park.  This now incredibly beautiful area of moss draped trees, cliffs and black rock/sand beaches was once a World War II gun site.  I saw the massive guns, the lookout that was half buried in the rock and the searchlight shelter.  Due to the northern site, there are times that the sun is not out for long so they had big searchlights that were rolled out of the structure to search for planes and ships out in the Pacific Ocean.  While there I got to see the resident Bald Eagles and other wildlife (no Kodiak bears yet but I keep looking).

Later, I was able to head to the southern shore of Kodiak Island to see where people surf on Surfer Beach.  Again, the sand is very dark and the waves were incredible.  I didn’t think Alaska was an area for surfing, but it is very popular.

The incredible Surfer Beach!

The incredible Surfer Beach!

After looking at Surfer Beach I was taken over to the Pacific Spaceport Complex Alaska.  I was able to let my Space Geek out.  Too bad I didn’t have my Blue Flight Suit, I could have had my picture taken there.  This is an active launch pad for launches over the Arctic.  They had an explosion here in November, 2014 (no one was hurt thankfully) so it is being repaired before more launches can take place.

On the ship, the crew is incredibly welcoming and helpful.  I am gradually learning my way around and how things work.  Off the ship, I used the time to connect with the local Kodiak High School and their award winning robotics team.  They are doing some pretty amazing things here with STEAM in this small coastal town.

More adventures to follow as we head out and I become a true Teacher At Sea, not just a Teacher In Port!

My name is Kathleen Gibson and I bring you greetings from Trumbull, CT where live and teach. In two weeks I will travel to Pascagoula, MS, located on the Gulf of Mexico, to join NOAA Corps members, research scientists, and the crew aboard NOAA Ship Oregon II, as a  2015 NOAA Teacher at Sea.

I work at Trumbull High School and currently teach Biology to sophomores and two elective courses for seniors–Marine Science and AP Environmental Science.  I’m passionate about environmental education and am always looking for opportunities to engage students in the world outside of the classroom.  Trumbull has a large amount of protected green space, wetlands, streams and a river, and while we aren’t on the coast, we are only a few miles from Long Island Sound.  The woods and the shoreline have become our laboratory.

The National Oceanic and Atmospheric Administration (NOAA) is an agency within the United States Department of Commerce that seeks to enrich life through science.  While NOAA is somewhat familiar to many of us– thanks to the abundance of weather data that is collected and disseminated to the public–that’s not all that is happening  there. NOAA is working to increase our understanding of climate, weather and marine ecosystems, and to use this knowledge to better manage and protect these crucial ecosystems.  In addition to the abundant educational resources available to all teachers, NOAA provides unique opportunities for teachers and students.  The Teacher at Sea Program  brings classroom teachers into the field to work with world-renowned NOAA scientists.

The Mission

The Mission of the cruise I will be a part of is to monitor Shark and Red Snapper populations in the Gulf of Mexico in the Atlantic Ocean off the Florida coast. Data collected will be compared to findings from previous years, as a part of the ongoing research studying inter-annual variability of these populations. We are scheduled to embark on July 25, 2015 and plan to sail from Pascagoula, MS, down the west coast of Florida and up the Atlantic Coast as far as Mayport, FL.

I am honored to have been selected to be a Teacher at Sea for the 2015 Season  and look forward to a number of “firsts”. I’ve never been to Mississippi nor have I been at sea for more than 24 hours. Also, I’ve only experienced sharks as preserved specimens or through aquarium glass.  I’m also looking forward to meeting my shipmates and learning about career opportunities and the paths that led them to be a part of this Oregon II cruise. I’ll share as much as I can through future posts. I’m excited to bring my students and others along with me on this journey.

Next Up?

My next post to you should be coming later this month from off the Mississippi coast.  However, the first rule of being on board is FLEXIBILITY, so things may change.  Either way, I’ll keep you posted. In the meantime, please check out some of the TAS 2015 blogs written by my fellow NOAA Teachers at Sea, and spread the word. There is so much to learn.

Did You Know?

  • While some sharks release eggs into the water where they will later hatch, as many as 75% of shark species give birth to live young.
  • Shark babies are called pups.

Integrated Tracking of Aquatic Animals of the Gulf Coast

One of the best games you can play in the pool is Sharks and Minnows. The premise of this game is that you and your school are small fish that have to travel from one side of the pool to the other without getting caught by the shark. If you are caught you get turned into a shark for the next round.  Eventually the sharks are well distributed, preventing any minnows from getting through.

Acoustic Monitoring Arrays in the Florida Keys National Marine Sanctuary

Acoustic Monitoring Arrays in the Florida Keys National Marine Sanctuary

I am reminded of this as the fin fish team from FWC sets up a grand game of sharks and minnows for fisheries science.  Over the past week we have been setting up several arrays of acoustic receivers that catch tagged fishes’ signals as they swim through the Florida Keys reef system.  The plan is designed to capture fish moving within and between different parts of the ecosystem.  Any tagged fish coming into Florida Keys National Marine Sanctuary should come into contact with one of the receivers, as will any fish traveling out.  The placement of the receivers on the west and east of the sanctuary create and “entrance” and “exit” for tagged fish.

Within the sanctuary there are now several concentrated grids of receivers in places that make for good fish habitat (aka good fishing spots).  The VR2 receivers can record the identification number of the tagged fish as well as the time and date they connected to the receiver and their distance from the receiver.  When the receivers are collected, that data can be downloaded and a picture of fish movement created.  The data from the FWC’s arrays and tagged fish will be incorporated into a more extensive project called ITAG (Integrated Tracking of Aquatic Animals of the Gulf Coast).   In this project, collaborators share their acoustic tag data and receiver logs with each other, extending the reach of all project.   In the vastness of our marine environments, any one project will produce only a small snapshot of what is happening.  By collaborating between projects, the complexity of fisheries and ecosystems might be more easily untangled.

Today we set up individual stations of a new device which uses an acoustic release.  These are for much deeper sites containing “humps” which are relief features rising 100 to 200  feet about the surrounding sea floor.  Because of the relief, humps offer a large variety of habitats in a small amount of space, creating a highly diverse area for aquatic life.  Since these deeper areas are inaccessible to most divers, the receivers we set out can be triggered to return to the surface.  When data is ready to be collected in a few months, a device will be lowered into the water that communicates with the receiver using sound.  This device, called a VR100, can trigger the receivers to jettison themselves to the surface with the help of two small floats.  At that time the receivers can be collected from a small boat.

City in the Sea

The Nancy Foster has been at sea since February of this year.  While it resupplies every few weeks, most of the vital functions for human habitation are performed on board.  The ship is, for its officers, crew, and science passengers, a small floating city.

View of the engine room control panels.

Electricity requirements for a large ship are quite high.  If you factor in air conditioning, navigation systems, lighting, motors and pumps, kitchen, and scientific tools, the energy consumption equals a small hamlet.  Amazingly, this electricity is all created on board with the ship’s generator and a copious amount of marine diesel.

The Nancy Foster has a main engine for thrust but several others that act as generators for the thrusters, electricity, and backup power.

Food is loaded on at ports but that doesn’t mean it isn’t fresh and delicious.  Each day Bob and Lito prepare breakfast, lunch, and dinner for all of the scientists and crew.  These delicious multi-course meals keep all the members of this floating city very happy.  Just like the hungry generators, the humans energy levels are kept well stocked.

Water, water everywhere but not a drop to drink, except on the Nancy Foster you can just distill it using excess engine heat.

There is no sewage processing on board the ship.  Ship waste is carried in large tanks until it can be released into open ocean, far from land.  Once in the ocean, its nutrients are quickly consumed by hungry phytoplankton and converted into energy for the next level of the food chain.  Food waste is also separated from recycling and “garbage”.  Food waste, after being ground, is composted at sea.

With 40 people on board eating, showering, and using the head, the ship needs to produce water on a continual basis.  The ship keeps a reserve supply and when it goes down, The Nancy Foster has a device that uses excess heat from the engines and generators to distill water from the ocean.

Every day the Science Chief and project leaders determine a schedule and make staff assignments.

Cities need organization and a specialized workforce to get all of these things done.  The NOAA Corps Officers make sure the ship stays on course and its mission objectives are met.  The ships crew ensures the small craft are launched safely, everyone is fed, and the ship keeps humming and running smoothly.  The science staff are visitors, enjoying all of the amenities of the ship while using its resources to complete their scientific missions.  Many of the science staff cruise with the Nancy Foster every year, while for some, it is their first time.

How did you get here?

I asked several of the scientists on board what they wanted to do when they were in middle school and how they became involved in marine science and research.  My middle school students are just starting to think about who they are and who they want to be.  I wanted to get some background information on how some of the scientists here got their start.

J. – A biologist had no clue what he wanted to do when he was in middle school and this trend continued until college! He loved fish and applied for an entry level fisheries job and has been at it ever since.

R. – Thinks she wanted to be a writer in middle school based on a paper she read from back then.  After pursuing her interest in ecology she is now writing about conservation issues for NOAA.

S. – She always loved science and math – After studying geology she had a chance to go to sea.  Loved it more than her geology work and now scans the sea floor of the Gulf of Mexico.  She won’t tell you where the treasure is!

P. – He took a test when he was in middle school that said he was not particularly interested in anything.  What he always liked was fish. After a couple related jobs he has worked in fisheries for many years.

S. – When he was in middle school he wanted to be rich and work in biology.  He now works in biology!

One of the major commonalities among the scientists is that they followed, or in some cases, rediscovered their interest.  As a teacher, I hope I can help my students find what they are passionate about.

ocean and bay

The Golden Gate Bridge between the Pacific Ocean and San Francisco Bay

My name is Sandra Camp, and I teach math and science to 5th graders at Robert Louis Stevenson Elementary School in the Sunset neighborhood of San Francisco in northern California. San Francisco is located on a peninsula, which means it is surrounded by water on three sides. On the eastern part of the city lies San Francisco Bay. The western side is bordered by the Pacific Ocean. The famous Golden Gate Bridge spans the divide between these two large and important bodies of water.

Me exploring tide pools


The Pacific is sometimes called the “Mother of all Oceans” because it is the largest ocean on our planet. Although we have many beautiful beaches here, in San Francisco the Pacific Ocean is much too cold for humans to swim in. Even though I can’t swim in it, I do love to go tide pooling along the Pacific Ocean, looking for tiny sea creatures when the tide goes out like sea stars, crabs, and anemones.

Being surrounded by so much water makes us care a great deal about the health of the world’s oceans and the plants and animals that live there. In our part of the Pacific Ocean, there are giant kelp forests. We are also home to many different kinds of marine animals, such as sea otters, harbor seals, elephant seals, crabs, sea lions, bat rays, and sharks. When there are healthy populations of these creatures living off the coast of northern California, it indicates that our part of the Pacific Ocean is healthy.

I am very excited, because in about a week I will be visiting a different part of the Pacific Ocean, a part where the ocean is warm enough to swim in! Hawaii is a chain of islands located in the northern Pacific Ocean.  Unlike San Francisco, islands are surrounded on all sides by water, and because the ocean water there is warmer, it allows coral reefs to grow.  I will be flying to Honolulu, Hawaii where I will board the NOAA (National Oceanic and Atmospheric Administration) Ship Hi’ialakai at its home port in Pearl Harbor. Do any of you know what Pearl Harbor is famous for?  If so, write your answer to me in the comments section of this blog.  As a Teacher at Sea, I will spend 10 days aboard the ship while scientists conduct reef fish surveys around the main Hawaiian Islands. This means that they will be studying the fish that normally live in the coral reefs around the islands. If there are healthy populations of these fish in the reefs, then that means the coral reefs are healthy. If not, then that indicates the reefs are having problems. Here is a picture of the Hi’ialakai. Its name means “embracing pathways to the sea” in Hawaiian.

It takes a lot of people to run a ship this big.  Stay tuned, because in addition to the scientists, I will introduce some of the people who work aboard the ship to you in my upcoming blogs.

coral polyps

What exactly is a coral reef, anyway? Coral reefs are ecosystems located in warm, shallow ocean water that are home to a very diverse amount of sea creatures, including fish, crabs, turtles, octopus, sharks, eels, and shrimp. Reefs are structures that are made from the skeletons of colonies of tiny animals called coral. The individual animals that make up the colonies are called polyps.  Polyps usually have a cylindrical-shaped body with a mouth surrounded by tentacles at one end.  The polyps use these tentacles to catch tiny animals that drift by called zooplankton, which they eat for food.

The coral polyps have a symbiotic relationship with algae. The algae help corals build their skeletons, and the corals provide the algae with protection and compounds they need for photosynthesis. Coral reefs are the largest structures built by animals on Earth! Sadly, coral reefs around the world are in danger because of human factors like pollution, over-fishing, and global warming.



Scientist Diving – photo courtesy of NOAA

Most of the scientific work aboard the Hi’ialakai will be conducted by scientists who are scuba diving. While they are under the water, scientists can take pictures of the ocean floor and the coral reefs, as well as count the number of reef fish they find. The information they gather will help them determine if the reefs around Hawaii are healthy places for animals to live. I will be sharing a lot more about the work they do with you in the blogs I write while I am aboard the Hi’ialakai.


Did You Know?

The Great Barrier Reef off the coast of Australia is over 1400 miles long! Even though coral reefs are the largest structures built by animals and are home to so many diverse species, they cover less than one percent of the ocean floor.
