Science Log
Before I left Scammon Bay, all of our students K-12 signed and decorated a Styrofoam cup. I carefully packed these cups and brought them onboard the Norseman II in order to send them to the bottom of the Bay with the ROV Kraken on one of its nighttime dives. So, last night was the night for the deepest dive! I stuffed paper towels into each cup and dropped them into a mesh bag. The ROV crew tied the bag of cups to the frame and down, down, down they went!

The Kraken descends!
About 6:30 the next morning, I hurriedly went up to check on our cups. Wow! All the cups were miniatures! The water pressure had compressed the air from the Styrofoam as the ROV had descended and the cups shrank!
Now all the students of Scammon Bay have a souvenir from the bottom of Glacier Bay! What a neat object lesson these little cups will be for all the kids at school. I hope it will be something they’ll never forget.
In addition to my excitement about my student’s cups, the scientists were excited about the samples brought up from the dive. A big Red Tree Coral sample was lying on deck. By its name you would think the coral is red. But it’s not. It’s kind of pinkish orange sherbet colored. It does look like a tree, though. The bottom of it looks like a young tree trunk. And it has rings like tree rings! According to Chief Scientist Rhian Waller, unlike tree growth rings, the rings aren’t indicative of yearly growth, but of growth due to abundance of food and living conditions.

Today, we steamed back toward Bartlett Cove. Bartlett Cove is the headquarters for the Glacier Bay National Park Rangers and the little town nearby is Gustavus. Gustavus has a population of 350 and the school has about 70 students. When we arrived in port, a sea otter greeted us, just hanging out. Eating while he floated on his back. He was noisily, crunching and smacking. Sea otters typically eat urchins, clams, and mussels. At one point he crawled out onto the dock to sun himself.
While in port, we had “open-ship” tours for the community of Gustavus. Scientists and ship’s crew took groups of ten through the Norseman II showing equipment, samples and answered questions. We were thrilled that about 65 people, including children with parents and grandparents, turned out and enjoyed learning about scientific research conducted in their Bay!

I rode into the little town of Gustavus with Ranger Sarah to drop Scientist Bob Stone off at the airstrip. Sarah drove us around on a tour. Gustavus is a beautiful little town with a gorgeous view of the Fairweather Mountain Range. One super cool thing that you can see in the Gustavus Public Library: an Orca skeleton hanging from the ceiling! Orca whales stay in Glacier Bay year round.

After the ship tours, the Park Rangers took us on a short walking tour around the visitor’s center. The National Park Service is partnering with the local Tlingit tribes in making this location once again a gathering place for them. They are building totem poles and a tribal meetinghouse designed by the tribal elders.
We learned that the Tlingit tribe lived in the area before the Bay was formed. It wasn’t yet a Bay because it was still covered in a giant glacier. The Tlingit still have songs and stories that tell of the glacier moving as fast as a dog running! So they hurriedly got in their canoes and fled to safety. As the glacier surged it destroyed their homes and scoured the land. They re-settled into places like nearby Hoonah, a native village across the way.
Before we left Bartlett Cove, everyone gathered with Qanuk and I on the dock sign for a photo with the winning banner designed by Scammon Bay 4th graders!

Now we’re all back on the ship and heading out to open waters. The glassy waters of the Bay are gone and it’s looking like a rough ride.
I already feel a bit queasy……
Personal Log
Since the ship’s work is ongoing 24-7, it seems that one day runs into the next because someone is always up and at work. And someone is always asleep in the stateroom. I’m amazed at how smoothly things work. Everyone pulls together to help each other and get the work done. If you think about it, there are LOTS of things going on. For example, the meals must be prepared and dishes washed. The science work must be done—scuba diving and processing during the day and ROV diving at night. The ship must be piloted and navigation is critical at all times. General housekeeping is always going on. It’s all an impressive operation and I’m happy to be here and hopefully a productive part of the team!

I created the video below to document some of my activities aboard the Oscar Dyson during my 2016 Teacher at Sea research trip.
In this video, Virginia opens with exciting footage from the front of the Oscar Dyson’s bow as they transit through Alaska’s Shelikof Strait. Interspersed, she shares various steps involved in processing the fish caught in the survey: sorting the catch by species (0:34), collecting the pollock into bins (1:00), making an incision to determine the sex of the pollock (1:07), measuring the pollocks’ lengths and taking biological samples (1:33), removing the otoliths (2:23 and 3:29), preserving the otoliths for analyzing on shore (3:12), and measuring and recording other fish using the Ichthystick and the CLAMS computer program (3:57). Virginia also takes the opportunity to show off some interesting species—lumpsucker fish (2:18), starry flounder (2:53), and salmon (3:53). Finally, Virginia gives a brief tour of the deck (4:38) and finishes with a photo of her wearing a survival (or “Gumby”) suit (5:02.)
My students know a good bit about my previous Teacher at Sea experience out of Woods Hole, Massachusetts where we used the HabCam to look at the ocean floor. With that knowledge in mind a couple of my students asked me if there was a way that we were able to look at the fish while they were still in the water. The simple answer to that question is yes. While my previous TAS experience used the HabCam, the Oscar Dyson uses a CamTrawl. The CamTrawl is attached to the net and it records pictures as fish enter the cod end of the net.
Image from the CamTrawl
CamTrawlNick and Ryan Attaching the CamTrawl to the Net
After each trawl we would use custom software written in MATLAB to measure lengths of pollock while they were in the water. This program uses the pictures taken from the CamTrawl during the trawl to measure the length of the fish. The CamTrawl takes two pictures at different angles so that most of the time we can see the same fish from two different angles. Fish length irregularities occur in the MATLAB program when it selects nets or two fish at one time to length, so therefore a person has to go back and check to make sure that the program has selected valid fish to length. As the fish pictures come up on the MATLAB screen the person rating the fish selects the fish when the yellow box around the fish covers most of the fish from both angle camera shots of the CamTrawl.
A Screen in MATLAB that Shows Valid Fish Lengths
The above picture shows three different fish that were valid choices for length measurement. The pictures on the left show one camera angle and the pictures on the right show the other camera angle. When both angles have a valid fish with the correct placement of the yellow box, the person selecting the fish will click the fish to tell the program to use that fish in the measurement data.
Interview With a NOAA Survey Technician: Alyssa Pourmonir
Alyssa Pourmonir inside the Wet Lab
How did you come to be in NOAA Corps? (or what made you decide to join NOAA Corps and not another military branch.
I am not in the NOAA Corps, instead I am a civilian government employee under the title of Survey Technician. I was in the US Coast Guard for 3 years where I took many courses related to navigation, leadership, and ship life. I feel my background in the Coast Guard has allowed me to excel in this demanding environment.
What is your educational/working background?
I have been lucky to have the opportunity to be in the Coast Guard which taught me many professional skills and built me up to be stronger and more independent. I also spent an entire summer forecasting for the weather in Pennsylvania. Here I gained an abundance of practice presenting the weather on the green screen and performing on live television for WNEP TV. Before coming to Alaska for this job, I worked as a consultant at NASA Stennis Space Center performing remote sensing analysis of forests using data from the MODIS and VIIRS data.
Academically, I have a BS in Marine Environmental Science from SUNY Maritime College, although most of my college experience took place at the US Coast Guard Academy.
How long have you been in NOAA Corps?
I’m not in the NOAA Corps, but I have worked for NOAA for almost 2 years as a Survey Technician. May 2014 to present.
How long have you been on the Dyson?
June 2014 to present.
How long do you usually stay onboard the ship before going home?
In the past 2 years I have visited my family one time. Partly because I wish to send money home so my family can struggle a little less and hopefully enjoy a life with less debt; especially as my father passes retirement age. He has worked several full time jobs at a time for many years just to support my mom and sisters. Potentially, his work ethic and care giving nature is what I try to embody each day.
Have you worked on any other NOAA ships? If so, which one and how long did you work on it?
Nope
What is your job description on the Dyson?
On the NOAA Oscar Dyson, I am a crew member who acts as a liaison to the scientific personnel on board. I work up to 12 hours each day, 7 days per week maintaining the scientific data, equipment, and lab spaces on board. I also work alongside the scientists, deck department, and bridge watch standers to collect data by completing many different oceanographic or fishing operations.
How is your science job on the Dyson different from the NOAA Scientists that you work with?
As a crew member, I facilitate a positive environment with the needed resources for the scientists to fulfill their data analysis and data collection. I also work alongside the scientists to process the fishing catch in our lab. So you can imagine me suited up with the scientists analyzing the fish’s reproduction development stages and extracting otoliths.
What is the best part of your job?
I get to explore and work in the infamous Bering Sea Alaska, Gulf of Alaska, and Aleutian Island chain which most people can’t even imagine doing. Here in Alaska, I do not have the luxuries found in Continental US, so I believe out here there is a great opportunity for character building. It takes someone pretty amazing to live out here and do what we do.
What is the most difficult part of your job?
Being in remote places and not seeing family or friends, but also being so far away that it is super expensive to try to see them.
Do you have any career highlights or something that stands out in your mind that is exceptionally interesting?
I began my BS absolutely hating biology. I dislike and do not eat seafood. I was skittish and would let my partners do all of the dissections during classes, and I felt that I knew nothing about biology. As a Marine Environmental Science major I decided to take as many biology electives as I could. I went from the lowest grade in my classes to someone who received one of the highest grades in each class. I graduated just one class shy of a minor in Marine Biology and now toss around fish on the NOAA Ship Oscar Dyson, a fisheries research vessel. While my first day I would jump when the fish would move unexpectedly, now I can analyze characteristics of the fish with little alarm and much confidence. It is amazing how I enjoy biology now. I hope to encourage others to confidently try new things, for with a little practice and hard work you may accomplish anything or overcome fears you may not have realized you had.
Do you have any advice for students who want to pursue a career with NOAA?
If you wish to pursue a career with NOAA, be sure to work hard to learn as much as you can, but also come out of your comfort zone to pursue as many volunteer or paid jobs that will give you work experience that correlates with your interests. Time management and resilience is often my secret to success.

A little while before sunset I caught a plane from Anchorage to the Chicago, O’Hare airport. The scenery and sunset leaving Alaska was beautiful!!!! I hope this won’t be the last time I get to come to Alaska, because it is a beautiful, adventure-filled part of the United States.
It was good to be back on land again when we got back to Kodiak, but I do miss being on the ocean!!

Finally back on land in front of the NOAA Ship Oscar Dyson!
This experience was wonderful for me, however for my students this experience was invaluable. I was able to communicate and share my experiences with them through email almost daily and they were also able to read my TAS blogs as they were posted. If they don’t learn anything else from my experiences in Alaska, which I know that they will, I hope they will learn that the world is theirs to explore, study, and learn about no matter how small the town is that they come from!!

Happy Birthday to Cheryl!
This is Cheryl!
Unbeknownst to Cheryl, Chief Scientist Rhian Waller, even though she was very busy preparing for the cruise, brought balloons, streamers, candles, and noisemakers to celebrate Cheryl’s birthday today.
Surprise Birthday Decor
The ship’s chef is secretly making her a cake. The celebration is slated for tonight at dinner. Shhhhh……
This morning, Chief Scientist Rhian Waller announced that we are steaming toward the end of the west arm of Glacier Bay to Johns Hopkins Glacier. This is a place where cruise ships take tourists in the Fall. But the Park Service has it closed during the Spring and Summertime because it’s a harbor seal nursery. The nightshift workers are trying to catch a few winks of sleep before we get there. No one wants to miss it. We are hoping for clear skies. Johns Hopkins Glacier is one of the few glaciers that is advancing instead of receding. As it advances, it is joining the Gilliman Glacier.

It’s 10:30 am and we’ve arrived sooner than I expected. Johns Hopkins Glacier is really something to see! So massive. Once again everyone is out on deck taking pictures and oohing and aahing.
The glacier has shades of blue and white with streaks of brown and gray. It has a covering of white snow that looks like cake icing. The glassy water is a blue-green color with a multitude of icebergs floating in it. Bob Stone uses a term we all like—“bergy bits”—meaning small pieces of floating ice. He even brought some “bergy bits” onto the ship for us to add to our water or soft drinks. So refreshing!

While on deck taking pictures we hoped to see the glacier calve and fall into the sea. It sounds like thunder. We waited and we waited and finally a couple of small ones happened. Also, a couple of snow avalanches slid off the mountains into the water leaving dirty brown streaks along the slopes.
Occasional avalanches leave dirty streaks in the glacier’s white snow covering
Our scuba divers went down for another exploratory look and came up with a first! They found Primnoa pacifica in the West Arm! This is the first Primnoa pacifica ever found here. They described it as spindly and small in comparison to the others found in the East Arm.
The scuba divers continue their search for Red Tree Coral.
The significance of this Red Tree Coral being in the shallow water is that it has been considered a deep-water coral. There are two broad categories of coral: warm-water coral and cold-water coral. Generally, warm-water coral live in shallow, tropical waters. Cold-water coral live in deep water. The emergence of cold-water corals like Primnoa pacifica in the shallow waters of Glacier Bay has caused scientists to re-evaluate their understanding and descriptions of these organisms.
The third and last scuba dive for today was described as “mud, mud, and more mud”. A bit of a disappointment but they did bring up an interesting little critter.
Maybe a sea peach?
This sea peach is a tan color here in the wet lab, but according to Bob, in its natural habitat it has a bright cherry red color.
Birthday party for Cheryl!
Well, it’s finally suppertime! That means “Birthday Party Time!” The ship’s chef, Harry served up a delicious meal of salmon, barbeque chicken, steamed kale, baked summer squash, scalloped potatoes and a big salad. For dessert, he prepared a layered chocolate cake with freshly made whipped cream and strawberries. Everyone sang “Happy Birthday” to Cheryl.
After she blew out the candles we went out on the deck and ate cake with new friends in the view of majestic mountains and glaciers.
A birthday to remember, I’ll say.
Now it’s back to work and the ROV crew is getting ready to deploy Kraken 2 for another night of exploration!

Personal Log
Today has been a day of anticipation and inspiring wonder. I’ve tried to stay out on deck watching the glacier. Hoping for calving and avalanches. It’s really neat to me that no one else is here. We haven’t seen anyone else except four Park Service employees who boated out to meet us today. I found out that there are over 1,000 glaciers in Glacier Bay National Park! Some of them aren’t even named. I enjoyed watching a couple of bald eagles sitting on icebergs. And the absolute coolest thing has been the discovery of Primnoa pacifica in the West Arm of Glacier! I could feel the excitement in the air!
It’s so thrilling to be a part of this scientific exploration and to learn from these world-class researchers!
NOAA Teacher at Sea Virginia Warren
Mission: Acoustic and Trawl Survey of Walleye Pollock
Geographical Area of Cruise: Shelikof Strait
on NOAA ship Oscar Dyson
Date: 3/20/16 – 3/22/16
Data from the Bridge (3/21/16):
Sky: Snow
Visibility: 8 to 10 nautical miles (at one point it was more like 2 to 3 nautical miles)
Wind Speed: 23 knots
Sea Wave Height: 4 – 6 feet
Sea Water Temperature: 5° C (41°)
Air Temperature: 0° C (32° F)
Barometric (Air) Pressure: 994.3 Millibars
Science and Technology Log:
The purpose of this research survey is to collect data on walleye pollock (Gadus chalcogrammus) that scientists will use when the survey is complete to help determine the population of the pollock. This data also helps scientists decide where and when to open the pollock fishery to fishermen. Data collection such as this survey are critical to the survival and health of the pollock fishery.
As I mentioned in a previous blog post, we use an AWT (Aleutian Wing Trawl) to complete the pollock survey. The AWT has two doors that glide through the water and hold the net open. The cod end of the net is where all of the fish end up when the trawl is complete.

Codend of the Net – This is where all the fish are when the trawl is brought up.
Trawl Door
After the trawl is brought back onto the boat, the cod end of net is dumped onto a hydraulic table. The hydraulic table is then lifted up so that it angles the fish down a shoot into the Wet Lab on a conveyor belt.
The door to the shoot is opened allowing fish from the table outside to be dumped down the shoot and on to the conveyor belt inside.
Kim and Virginia sorting fish on the conveyor belt.
Once the pollock come through the shoot and onto the conveyor belt, the first thing that we do is pick out every type of animal that is not a pollock. So far we have found lots of eulachons (Thaleichthys pacificus), jellyfish (Cnidaria), isopods, and squid. We have even found the occasional chinook salmon (Oncorhynchus tshawytscha), rock fish (Sebastes spp.), and a lumpsucker (Cyclopteridea). The pollock continue to roll down the conveyor belt into a plastic bin until the bin is full. Then the bin of pollock are weighed.

The data from every fish we sample goes into a computer system called CLAMS. CLAMS stands for Catch Logger for Acoustic Midwater Survey. While we are taking samples of the fish our gloves get covered in fish scales and become slimy, so to be able to enter the data into the CLAMS system without causing damage there is a touch screen on all of the computers in the Wet Lab.
CLAMS computer system with a touch screen.
Once the pollock are weighed, a sample of the fish are taken to be sexed. To sex the fish, we use a scalpel to slice into the side of the fish. The picture of the chart below shows what we are looking for to determine if a pollock is male or female. Once we know what sex the fish is, we put it into a bin that says “Sheilas” for the female fish and “Blokes” for the male fish.
This chart of the Maturity Scale for Walleye Pollock is hanging in the Wet Lab.

Kim showing Virginia what to look for when sexing the fish.
Once the fish are in their correct male/female bin, they are then measured for their length using an Ichthystick.
The Ichthystick has a magnet under the board. When the fish is placed on top of the board, a hand held magnet is placed at the fork of the fish tale. Where the hand held magnet is attracted to the magnet under the board tells the computer the length of the fish and the data is automatically stored in the CLAMS program.
Ichtystick
Getting the length of the starry flounder using the Ichthystick.
The next station is where the stomach, ovaries, and otoliths are removed from the fish and preserved for scientists to research when the survey is over. The ovaries of a female fish are weighed as well. Depending on the size of the ovaries, they may be collected for further research. Once all of the data has been collected from the fish, a label is printed with the data on it. This label is placed in the bag with the stomach or ovaries sample. Kim completes a special project for this survey. She is a stomach content analysist, so she collects stomachs from a sample of fish that will be taken back to her lab to analyze the stomach content of what she collected. She puts the stomach and the label with the fish’s information, into a bag that is placed in a solution of formalin that preserves the samples.

The next step is to get the otoliths out of the fish. A knife is used to cut across the head of the pollock. Otoliths are used to learn the age of the fish. The otoliths are placed in a glass vile that has a barcode number that can be scanned and put with all of the fish’s information in CLAMS. This number is used to keep track of the fish data for when the otoliths get analyzed later on.
Getting the Otoliths

We also collect length, weight, sex, and stomach samples from other fish that come up in the trawl as well.
Interview with a NOAA Corps Officer: Ensign Caroline Wilkinson Caroline is a Junior NOAA Corps Officer on board the NOAA ship Oscar Dyson. She is always very helpful with any information asked of her and always has a smile on her face when she does so. Thank you Caroline for making me feel so welcomed on board the Dyson!
Ensign Caroline Wilkinson
How did you come to be in NOAA Corps? (or what made you decide to join NOAA Corps and not another military branch?
I graduated from college in May of 2015. I was looking for a job at a career fair at my school and discovered the NOAA Corps. I had heard of NOAA, but didn’t know a lot about NOAA Corps. I wanted to travel and NOAA Corps allowed me that opportunity. I was unsure what type of work I wanted to do, so I decided to join and explore career options or make a career out of NOAA Corps.
What is your educational/working background?
I went to the University of Michigan where I received an undergraduate degree in ecology and evolutionary biology and a minor in physical oceanography.
How long have you been in NOAA Corps?
July of 2015 I started basic training. Training was at the Coast Guard academy in a strict military environment. We had navigation and ship handling classes seven hours a day.
How long have you been on the Dyson?
I have been here since December of 2015.
How long do you usually stay onboard the ship before going home?
We stay at sea for two years and then in a land assignment for 3 years before heading back to sea.
Have you worked on any other NOAA ships? If so, which one and how long did you work on it?
Nope, no other ships. I had no underway experience except a five-day dive trip in Australia.
Where have you traveled to with your job?
We were in Newport, Oregon and then we went to Seattle, Washington for a couple of weeks. Then we went to Kodiak and then to Dutch Harbor.
What is your job description on the Dyson?
I’m a Junior Officer, the Medical Officer, and the Environmental Compliance Officer. As a junior officer I am responsible for standing bridge watch while underway. As a Junior Officer I am responsible for standing 8 hours of watch, driving the ship, every day. As medical officer, we have over 150 drugs onboard that I am responsible for inventorying, administering, and ordering. I also perform weekly health and sanitary inspections and Weekly environmental walkthroughs where I’m looking for any safety hazards, unsecured items, leaks or spills that could go into the water.
What is the best part of your job?
Getting to drive the ship.
What is the most difficult part of your job?
Being so far away from my family and friends.
Do you have any career highlights or something that stands out in your mind that is exceptionally interesting?
During training we got to sail in the US Coast Guard Cutter Eagle. It’s a tall ship (like a pirate ship). We were out for eight days. We went from Baltimore to Port Smith, Virginia and had the opportunity to do a swim call 200 miles out in the Atlantic.
What kind of sea creature do you most like to see while you are at sea?
We have seen some killer whales and humpback whale in the bay we are in this morning. We’ve also seen some albatross.
Do you have any advice for students who want to join NOAA Corps?
You need an undergraduate degree in math or science. There are 2 classes of ten students a year. Recruiters look for students with research experience, a willingness to learn, and a sense of adventure.

Personal Log:
I have really been enjoying my time aboard the Oscar Dyson and getting to know the people who are on the ship with me. I love spending time on the Bridge because you can look out and see all around the ship. I also like being on the bridge because I get to witness, and sometimes be a part of, the interactions and camaraderie between the NOAA Corps Officers that drive/control the ship and the other ship workers.
Panoramic view of the NOAA Ship Oscar Dyson‘s Bridge. Look at all of those windows!
Arnold and Kimrie are responsible for making breakfast, lunch, and dinner for all 34 people on the Oscar Dyson. They also clean the galley and all of the dishes that go along with feeding all of those people. They probably have the most important job on the ship, because in my previous experiences, hungry people tend to be grouchy people.
Arnold and Kimrie are the stewards of the Oscar Dyson.
We’ve had a variety of yummy dishes made for us while we’ve been at sea. Breakfast starts at 7 a.m. and could include a combination of scrambled eggs, breakfast casserole, French toast, waffles, chocolate pancakes, bacon, sausage, or my personal favorite, eggs benedict.
Breakfast is served. YUM!!!
Lunch is served at 11 a.m. and seems like a dinner with all of the variety of choices. Lunch usually has some type of soup, fish, and another meat choice available, along with vegetables, bread, and desert. Dinner is served at 5 p.m. and usually soup, fish, and another meat choice available, along with vegetables, bread and desert. I loved getting to try all of the different types of fish that they fix for us and I also really liked getting to try Alaskan King Crab for the first time!!
If you are still hungry after all of that, then there is always a 24-hour salad bar, a variety of cereal, snacks, and ice cream available in the galley. The left-overs from previous meals are also saved and put in the refrigerator for anyone to consume when they feel the need. If we are working and unable to get to the galley before a meal is over, Arnold or Kimrie will save a plate for us to eat when we get finished.
I also tried Ube ice cream, which is purple and made from yams. At first I was very skeptical of any kind of sweet treat being made out of yams, but I was pleasantly surprised that it tasted really good!
Ube ice cream made from yams! Very YUMMY!!!
There is even a place to do laundry on this ship, which I was very happy about because fishy clothes can get pretty stinky!

My lab work: a tray of Primnoa pacifica samples labeled and preserved for reproductive studies
Today, the coral processing continued for genetic, isotope, and reproductive studies, which has been very intensive for the last two days and nights. During the daylight hours, the divers collected samples of the coral in shallow water (30 meters) and during the nighttime hours ROV Kraken 2 collected the coral samples from the deep (210 meters).
Chief Scientist Rhian Waller tells me that the coral processing work will slow down for a few days because we are leaving the known sampling sites and heading into the unknown. Unknown territory for Primnoa pacifica, that is.
According to Rhian, the most important task today has been the completion of this collection series for Primnoa pacifica (Red Tree Coral). With both shallow and deep samples, geneticist Cheryl Morrison will be able to map the spreading patterns of the Red Tree Coral in Glacier Bay!
There were a total of four exploratory dives today. The divers are having a blast! They wore GoPro cameras on their helmets and used “underwater scooters” to go faster and farther during their dive time constraints. A scooter is a handheld engine with a propeller that pulls a diver behind it. Bob Stone describes it to be like sledding underwater!
In addition to the Red Tree Coral, they’ve brought up some really interesting specimens, which include sea stars, nudibranchs, shrimps-one very pregnant shrimp loaded with eggs, a polychaete worm, a bioluminescent ctenophore, sea pens, and sponges.

On one of the dive outings, they took Qanuk and sat him on an iceberg! It was a really beautiful blue iceberg. Blue icebergs have ice crystals that are more tightly packed therefore they reflect more blue light wavelengths than other colors of wavelengths.
This evening, scientists are once again gathered around the monitor to see what the ROV Kraken 2 will discover. So far, we’ve seen crabs, goose barnacles feeding on plankton floating in the water, anemones, poacher sturgeon, sea cucumbers and moon snails. Sounds like a yummy salad, doesn’t it?

Personal Log
Today everyone settled into their jobs and it was a smooth operation. The scientists and crew are still brimming with excitement about the possibilities for this voyage. I was glad to get the intensive coral processing completed. Though it’s very important work, it’s tedious and repetitive. One very nice bi-product of working with the coral is the scent. Red Tree Coral smell like cucumbers! Also, we get to see all the other curious types of samples brought aboard such as glowing ctenophores and jumping shrimp! I’m getting to see so many things I’ve never seen before and it’s wonderful to have experts help explain everything. They are genuinely interested in sharing knowledge with me in hopes that I will take it back to the classroom for my students in Scammon Bay. Scammon Bay kids have become important to these world-class scientists! Another cool thing about these scientists, even though they are experts in their fields, they are also eager students for learning something new. Enthusiastic lifelong learners— what an inspiration!
