Her foot 6. Designed for operations in Alaskan waters, Oscar Dyson has an ice-strengthened welded-steel hull. In addition to her crew of 24, she can accommodate up to 15 scientists. She makes weather and sea state observations, conducts oceanographic research and habitat assessments, and surveys marine mammal and seabird populations. In and , Oscar Dyson took scientists to the Bering Sea so that they could capture seals on the ice there and attach satellite tags to them with which to collect movement and behavior data.
The test demonstrated the feasibility of using UAVs to assess the abundance and distribution of seals, which began in the spring of From Wikipedia, the free encyclopedia.

Dyson — , Alaskan fisherman and fishing industry leader. Once all the fish are sorted, the jellies get sorted too, which is where the jellyfish face smack comes in. Picture a smallish conveyor belt with 5 people standing around throwing fish, squid, isopods, and jellyfish into appropriate bins.
It turns out that when you throw jellyfish into a bin, it sometimes explodes on impact causing jellyfish goop to go flying, and sometimes it flies onto my face. We caught a cool looking smooth lumpsucker fish. Here I am holding the smooth lumpsucker. These are my favorite because they pull up lots of plankton. The deck crew and survey tech bring in the bongo nets. Most people would totally freak out if they knew how much stuff was swimming around in the water with them, including pteropods, which look a bit like slugs with wings.
The ones we got today were big enough to be slugs. My goal over the next couple of weeks is to get a decent video of them swimming. Personal Log Peer pressure is a powerful thing. In this case, positive peer pressure was a good thing. Eau de poisson anybody?
The biggest adjustment has been the time change and 12 hour work shift from noon to midnight. I like to describe myself as the oldest, young person alive. Judging by the 9. I can also report that the food on board is delicious. Ava and Adam crank out tasty options at every meal, and somehow meet the needs of about 35 people some of whom are vegetarian, vegan, low acid, etc.
Since Kodiak was a washout, I tagged along on the shopping trip prior to our departure. Five shopping carts later we were ready to eat our way across the Gulf of Alaska! Did You Know? NOAA scientists on board the ship rotate through different at sea research cruises throughout the year. They even participate on cruises that have nothing to do with their actual research. The winds are out of the NE at about 13 mph right now. Forecasts predict mild flash flooding and some tidal flooding around the 2 pm high tide.

It also has numerous labs onboard, including a wet, dry, bio, and hydro lab. Courtesy of NOAA. Image courtesy of NOAA. What does that mean exactly?
Well, it means that scientists will collect Walley e Pollock data to get an idea of what the population looks like. To collect these samples, scientists will be using a variety of tools. Bongo nets will be used to collect zooplankton samples. A Stauffer trawl net will be used to sample fish species.
A CTD rosette CTD stands for conductivity, temperature, and density will be used along the way to corroborate that the other water data equipment is indeed working correctly. Scientists, like mathematicians, do love to double check their work. Did you know that NOAA is part of our daily lives? This map on the bridge helps everyone keep track of where we are and where we are headed next. At each sampling site, we take two types of samples. First, we dip what are called bongo nets into the water off of the side of the boat.
These nets are designed to collect plankton. Plankton are tiny organisms that float in the water. Then, we release long nets off of the back of the boat to take a fish sample. There is a variety of fish that get collected.
However, the study targets five species, one of which is juvenile walleye pollock, Gadus chalcogrammus. These fish are one of the most commercially fished species in this area. I will go into more detail about how the fish samples are collected in a future post. For now, I am going to focus on how plankton samples are collected and why they are important to this survey.
Juvenile walleye pollock are fish that are only a few inches long. These fish can grow to much larger sizes as they mature. As you can see in the photos below, the bongo nets get their name because the rings that hold the nets in place resemble a set of bongo drums. The width of the nets tapers from the ring opening to the other end.
This shape helps funnel plankton down the nets and into the collection pieces found at the end of the nets. These collection devices are called cod ends. Bongo nets being lowered into the water off of the side of the ship. This is the collection end, or cod end, of the bongo nets. This study uses two different size bongo nets. The larger ones are attached to rings that are 60 centimeters in diameter. These nets have a larger mesh size at micrometers.
The smaller ones are attached to rings that are 20 centimeters in diameter and have a smaller mesh size at micrometers. The different size nets help us take samples of plankton of different sizes. While the bongo nets will capture some phytoplankton plant-like plankton they are designed to mainly capture zooplankton animal-like plankton.
Juvenile pollock eat zooplankton. In order to get a better understanding of juvenile pollock populations, it is important to also study their food sources. Here I am, helping to bring the bongo nets back on to the ship. Once the bongo nets have been brought back on board, there are two different techniques used to assess which species of zooplankton are present.
The plankton in nets 1 of both the small and large bongo are placed in labeled jars with preservatives. These samples will be shipped to a lab in Poland once the boat is docked. Here, a team will work to identify all the zooplankton in each jar. We will probably make it to at least sixty sampling sites on the first leg of this survey.
A jar of preserved zooplankton is ready to be identified. The other method takes place right on the ship and is called rapid zooplankton assessment RZA. In this method, a scientist will take a small sample of what was collected in nets 2 of both the small and large bongos. The samples are viewed under a microscope and the scientist keeps a tally of which species are present.
This number gives the scientific team some immediate feedback and helps them get a general idea about which species of zooplankton are present. Many of the zooplankton collected are krill, or euphausiids, and copepods. One of the most interesting zooplankton we have sampled are naked pteropods, or sea angels. We also saw bioluminescent zooplankton flash a bright blue as we process the samples. Even though phytoplankton is not a part of this study, we also noticed the many different geometric shapes of phytoplankton called diatoms.
A naked pteropod, or sea angel, as seen through the microscope. Both the scientific crew and the ship crew work one of two shifts. Everyone works either midnight to noon or noon to midnight. I have been lucky enough to work from 6am — 6pm. This means I get the chance to work with everyone on board at different times of the day. It has been really interesting to learn more about the different ship crew roles necessary for a survey like this to run smoothly.
One of the more fascinating roles is that of the survey crew. Survey crew members act as the main point of communication between the science team and the ship crew. They keep everyone informed about important information throughout the day as well as helping out the science team when we are working on a sample. A sign of another great day on the Gulf of Alaska. You brush your teeth with diatoms!
The next time you brush your teeth, take a look at the ingredients on your tube of toothpaste. Diatomaceous earth is a substance that contains the silica from ancient diatoms. Silica gives diatoms their rigid outer casings, allowing them to have such interesting geometric shapes. This same silica also helps you scrub plaque off of your teeth! Diatoms as seen through a microscope. In Station Model format, of course.
How else would we practice? This August will kick off my 14th yikes! I am an alumna, so this is my second official voyage through the Teacher At Sea program. It was all of the wonderful people I met, lessons I learned, and science that I participated in on the. This is my husband, Stephen, and I, at the game that sent the Broncos to the Superbowl! Oscar Dyson in that led me to encourage my school to put an Oceanography course in place for seniors as a capstone course.
This past year was the first year for the Oceanography and Meteorology courses, and they were very well received! I have three sections of each class next year, as well! Shout out to all my recent senior grads reading this post! You were awesome! Apart from being a teacher, I am a wife to my husband of 8 years, Stephen. We enjoy camping, rock climbing, and hiking — the typical Coloradans, though we are both originally from Michigan.
Cetaceans live in the ocean, and are characterized by being carnivorous we will get along just fine at the dinner table and having fins since I am a poor swimmer, I will humbly yield to what I can only assume is their instinctive expertise.
We have a whale! The observers who tackle this task are sharp and quick at what is truly a difficult and impressive skill. Where do you see it? And we will be out on the water until we locate every last one. Just kidding.
But we will be looking to spot all of these species, and once found, we will do our best to estimate how many there are overall as a stock estimate. Once identified in this broad sense, they will then be identified by species. However, I do have a feeling these two categorizations happen all at once. Once the data is collected, there is an equation that is used to project stock estimates for the whole of the Pacific.
Our chief scientist is Dr. Erin Oleson, who will be the lead on this leg of the cruise. HICEAS is a day study, of which we will be participating in approximately 30 of those days for this particular leg. Our research area is 2. There is a second team of scientists working below deck listening for Cetacean gossip whale calls as well.
Acoustic scientists will record the whale or dolphin calls for later review and confirmation of identification of species, and, of course, general awesomeness. Recall that in areas near the equator, rapid changes of temperature, salinity, and density with depth are pretty common year-round, but at the middle latitudes, these form and dissipate through the course of the solar year.
These density changes with depth can block nutrients from moving to the surface, which can act as a cutoff to primary production. Further, the CTD readings will help the acoustic scientists to do their work, as salinity and temperature variations will change the speed of sound in water. This study is enormous in scope. Dolphins are far more prevalent, and far more talkative. But both species are wicked-smart, using sonar to communicate underwater.
Virginia also takes the opportunity to show off some interesting species—lumpsucker fish , starry flounder , and salmon 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. The simple answer to that question is yes. Image from the CamTrawl. 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.
The pictures on the left show one camera angle and the pictures on the right show the other camera angle. Alyssa Pourmonir inside the Wet Lab. I was in the US Coast Guard for 3 years where I took many courses related to navigation, leadership, and ship life. I also spent an entire summer forecasting for the weather in Pennsylvania.
May to present. 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. 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.
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.
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. 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. 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.
I went from the lowest grade in my classes to someone who received one of the highest grades in each class. 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.
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. After the plane got into the air and was flying away from Kodiak, we were treated to a flyby of the Kodak Harbor and even got to see the Dyson outside of the harbor as we flew away.
Aerial view of the Kodiak Harbor. Mountains Outside the Anchorage, Alaska Airport. The scenery and sunset leaving Alaska was beautiful!!!! It was good to be back on land again when we got back to Kodiak, but I do miss being on the ocean!! Bow of the 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. 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. 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.
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. 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. Up-close of the Maturity Scale for female pollock. 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. 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.
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. This number is used to keep track of the fish data for when the otoliths get analyzed later on.
We also collect length, weight, sex, and stomach samples from other fish that come up in the trawl as well. 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! Have you worked on any other NOAA ships? If so, which one and how long did you work on it? Do you have any career highlights or something that stands out in your mind that is exceptionally interesting? Ensign Caroline Wilkinson at the helm.
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. 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.
Breakfast starts at 7 a. Breakfast is served. Lunch is served at 11 a. 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. 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 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! There is even a place to do laundry on this ship, which I was very happy about because fishy clothes can get pretty stinky! Laundry Room. The pictures below are of the Semidi Islands. When we left the transect line, we went through Alitak Bay and stopped the ship in front of Hepburn Peninsula, with Deadman Bay to the left of the peninsula and Portage Bay to the right if you are looking at the map.
Where the ship was sitting, the bay was The calibration process of the echo sounder took some time. The science crew before me already started the process of calibrating the echo sounder before it was time for my shift to take over. They used three down riggers to send three lines under the center of the boat, where the echo sounder is positioned.
A calibration sphere was placed a little further down one of the lines. There is also a lead weight put at the end of the line so that it will help hold the calibration sphere in place as the current moves. Then one of the science crew uses a system to align the calibration sphere with the echo sounder.
There are two types of calibration spheres that we used today. The first, and smaller one, was made out of a tungsten-carbide alloy. The second calibration sphere was larger than the first and it was made out of solid copper.
This made for a very easy, get a blog done, day for me because the job was completed by the lead scientist Patrick and Robert, one of the other science crew members. Echo-sounder display during calibration. On the echogram depth on vertical axis, time on horizontal axis you can see the calibration spheres hanging below the ship above the seafloor.
She has been great in helping me get accustomed to sea life and training me on what to do while we are sorting trawls in the science lab. She also agreed to let me interview her to share her story with my students. I am extremely grateful for all of the help, training, and friendship she has provided while I have been on the Dyson.
Her interview is below:. What is your educational background? How often do you go on a survey? Usually twice during the summer for about three weeks at a time. What is a highlight for you while at sea? A family of 4 got lost at sea and had been missing for 60 hours. We were out on survey and came across them in their life raft. We were able to pull them out. What made you want to be a scientist? I spent a lot of time on the water as a kid crabbing and playing in the water.
I was always drawn to sea life and I wanted to learn as much about it as I could. What enjoy most about being a scientist? The survey work is my favorite part of my job. A lot of deep water species. I also like going out on survey because most of my work is done in the lab looking at samples under a microscope.
What is the hardest part of your job? We have a sampling plan that tells us what species and what size range of fish we want to collect stomachs from. Any advice for people who want to be a scientist? Volunteer as much as you can. Hard work and enthusiasm are what helped me get where I am today in my career. Personal Log: For the first couple of days on board the Dyson we had beautiful weather blue skies, pretty clouds, beautiful scenery, and calm seas.
However, experiencing calm seas came to a halt on Thursday. The wind picked up which caused the ship to rock back and forth with the waves. Gusts of wind would cause water to splash over the bow of the ship, creating a very entertaining show.
When I went to visit the bridge of the ship one wave hit the boat hard enough to ring a bell that is hanging in the bridge. Sitting down to do work or eating a meal can be kind of fun when the wind is up. Walking while the ship was rocking was also interesting because two normal steps could become 5 so that you can keep your balance and stay on your feet.
On Friday we had our mandatory at sea drills. The first was a fire drill which was very easy for me because all I had to do for that drill was meet up with the rest of the science crew in a preplanned muster station. The next drill was a little more eventful. We had to bring a survival suit, a life jacket, a hat, and gloves to the preplanned muster station. Once we were there roll was called to make sure we were in the correct station to get on the correct life raft should it became necessary.
However, after that part was complete the people new to the ship had to put on the survival suit, which is supposed to take less than a minute to put on. He was very patient with me and also took my picture when I was finally able to get it on. My First Time in a Survival Suit. NOAA is a government agency that helps keep citizens informed on weather conditions and the climate. It also conducts fisheries management, and coastal restoration.
The officers keep the ship functioning properly and the people safe. This is my second full day on the ship and my science crew has sorted three trawls. On the first day on shift, I learned that there is a lot of waiting to get the fishing pollock job done correctly. The Chief Scientist, Patrick, is responsible for choosing where and when to launch the trawl. He does this by watching data on a screen that comes from the echo sounder, which is placed under the ship.
When you see bright red color on the screen, then you know there is something registering on the echo sounder. This part of the process can take several hours. Echo Sounder Screen. Once you find the fish, then you have to launch the trawl net. This is a very intricate process because as the net is being launched, it has to be kept free of tangles.
If tangles occur in the net it could cause the net to rip once the trawl has begun. Once the trawl is complete, the catch is dumped onto a table that lifts up to the conveyor belt where we separate pollock from all the other types of animals. The pollock are placed into baskets where they are then weighed. A sample of pollock is taken to examine further. I will further explain the sorting and data collection processes, and the CLAMS program on a future blog.
Kodiak is a beautiful, scenic fishing community. I love that Kodiak is able to use clean, alternative-renewable energy resources to make their energy for the island. Notice the wind turbines in the picture below, however Kodiak also uses hydroelectric dams to make most of their power. Wind Powered Turbines. The Oscar Dyson anchored up outside of the Kodiak harbor in efforts to save time by not having to completely dock up in the harbor. We put really warm jackets that also served as life jackets float coats.
Beautiful Mountains from the Harbor in Kodiak, Alaska. My first view of the Oscar Dyson was spectacular. I saw it as we rounded a very small island outside of the harbor. With the mountains in the background, the ship made a pretty picture. My name is Virginia Warren. I have been a teacher for 6 years. I am set to fly out of Pensacola, Florida this coming Thursday morning. Then, I will be off again to Seattle, Washington where I will stay the night before finishing my journey the next day.
I am excited about getting to spend even a short amount of time in Seattle because I have never been on the West Coast of the United States. As a teacher this experience has become invaluable to me because it made scientific research come alive to me in way that I had never been able to express to my students prior to this experience. I am also excited to be able to share this trip with my 5th grade students back home in Grand Bay, Alabama.
Weather Data from the Bridge: Latitude: 57 Birds are always abundant after a trawl Sunset from the ship. Aside from our survey, there is a lot of other science taking place on the ship. In fact, science is all around us. The officers on the bridge are using science when they use weather patterns and sea swells to calculate the best course of navigation for the ship. The survey technicians are using science when they collect water samples each day and test the salinity of the water.
The engineers are using science when they are monitoring the ballast of the ship. Today we look at a different realm of science, the engineering world. I recently had the opportunity to tour the brains of the ship with two of our engineers on board. I not only learned about the construction of the ship, but I also learned about the various components that help the ship run.
Data have been collected over the years that show fish avoid loud vessels by diving down deeper or moving out of the way of the noise. There was concern that this avoidance behavior would affect the survey results; thus the creation of acoustic quieting technology for research vessels.
It turns out 2 of our engineers are from San Diego, the place I lived for my first 21 years of life. Nick even graduated from Westview High School, the rival of my high school, Mt. Carmel albeit 10 years after me. The engineers are responsible for making sure everything is working on the ship.
In addition to taking me on a tour around the innards of the ship, Nick and Rob also sat down for an interview about marine engineering. Nick, Rob, and…. Nick: I played soccer throughout high school and was recruited during my senior year by the US Merchant Marine Academy. I went to school there, played soccer, and received a BS degree in marine engineering. I spent 1 of my 4 years at sea doing hands-on training. I was also commissioned into the US Navy as a reservist. I started at Scripps Institute of Oceanography in and worked my way up ranks from oiler to engineer.
Nick: As a second engineer, I give fuel reports and transfer fuel to maintain stability of the ship. We have saltwater tanks for ballast, which changes as we burn fuel, and I help monitor this. Rob: As a first engineer, I am the supervisor of engine room and am responsible for how everything is operating. I get updates on the fuel status, and communicate with CO of the ship if changes need to be made. My position is more supervisory, and I oversee responsibilities and delegate tasks.
I handle the plant and the people. Rob: Money and travel; getting to see things in ocean that most people would only see on National Geographic. Rob: I agree with Nick. Our life exists in ft. I am able to take frustrations and put it into things I enjoy, such as working out, reading, or playing guitar. What is something unique to being an engineer on a ship as opposed to an engineer on land? Nick: You have to have knowledge of every square inch of the ship; the two things I think about are: are we sinking and are the lights on.
Rob: You have to keep things going when you have big seas, and you have to have the knowledge and ability to handle problems and stay on your feet literally. If it makes you happy, keep doing it. And know your math!
You get to break stuff and fix it. Rob, Nick and I. Looked like the pipes needed a little fixing…. Welding is more difficult than it looks. Drew helping me hold the rod for welding. Drew is helping me weld My welding masterpiece Messing around in the engine room. Running the lathe. This baby humpback whale was having a blast breaching over and over again.
The ringing of the phone woke me up from the gentle rolling of the ship. I had told the officers and scientists to wake me up if there was anything cool happening, and an excited ENS Gilman spoke into the receiver claiming there were hundreds ok, maybe hundreds was a bit of an exaggeration of whales breaching and swimming around the ship.
Throwing on a sweatshirt and grabbing my camera, I raced up to the bridge to get a view of this. I had low expectations, as it seemed that every time we got the call that there were whales around, they left as soon as we got up there. This time, however, I was not disappointed. It was a whale extravaganza!
Humpback whales, fin whales, orcas, there were so many whales it was hard to decide where to point my camera or binoculars. Like one of those fountains that spurt up water intermittently through different holes, the whales were blowing all around us. I was up on the bridge for over an hour, never tiring to see which one would spout next, or show us a fluke before it dove down deep, only to resurface somewhere else 15 minutes later.
My favorite shot was of a baby humpback breeching — we had been tracking him for a while, his blow noticeably smaller than the adults around him. He looked as if he was just playing around in the water, enjoying himself without a worry in the world. I had been hoping to see Alaska wildlife on this trip, and am thrilled my wish was granted. A pod of orcas was amidst the whale extravaganza! The sight of the fluke indicates they are diving down deeper, and may not resurface again for several minutes.
So many whales! The bathroom in our staterooms. I share a room with another one of the scientists, and she works the opposite shift. This works out nicely as we can each have our own time in the room, and can sleep uninterrupted. We have bunks, or racks as many refer to them, and I am sleeping on the top bunk. The walls are pretty thin, and the ship can be loud when operations are going, making earplugs or headphones helpful.
Weather Data from the Bridge: Wind speed knots : 8. Parasites — some lurk inside our bodies without us knowing and some could even have an influence on our personalities. In addition to capturing our interest because of their sci-fi-like existence, parasites may also be utilized to study ecological interactions.
Nematodes on Pollock Liver — most of the Pollock we caught have had these in their guts. Parasites often require several hosts to complete their lifecycles and one nematode that can infect Pollock and humans incidentally is Anisakiasis. The pathobiologists at the Alaska Fisheries Science Center are currently investigating the impacts certain parasites may have on Pollock.
Scientists are attempting to identify those that are likely to influence the booms and busts that can occur within the Pollock populations. AFSC Pathobiology. Microsporidian pleistophora sp. These critters are found in most Pollock catches as well — they are also called sea lice. Sometimes ships pick up parasites too! The introduction of invasive species to fragile ecosystems is one of the leading causes of extinction and ballast water is the number one reason for the distribution of aquatic nuisance species.
The Great Lakes region serves as a warning about the devastation ballast water can inflict on an ecosystem. Ships can transport ballast water from one region to another and then release the ballast water along with numerous non-native organisms. No longer encumbered by natural predators or other environmental pressures that help to keep populations in check, the invasive species can flourish, often at the expense of the native species.
NOAA has implemented strict guidelines for the release of ballast water to limit the spread of invasive species. The Oscar Dyson also uses a lot of oil to keep all the working parts of our engine room functioning, but some of this oil drips off and collects in the bilge water. This oily bilge water is then separated and the oil is used in our trash incinerator all garbage with the exception of food scraps is burned in the incinerator.
Thanks, Allan! Our wonderful chefs, Arnold Dones and Adam Staiger, have been cooking healthy, varied meals for 32 people over the course of three weeks — this is no small feat! The soups are my favorite and have inspired me to make more when I return home. Last night, the chefs spoiled everyone with steak and crab legs! Chef Adam Staiger is always full of smiles!
Sunrise in Alaska. When the fog lifts, hidden beauties and dangers are revealed. A view of the Gulf of Alaska. In front of Kuiukta Bay. Mitrofania Bay. Sandy Point, Alaska. His placard reads the following:. Oscar Dyson Plaque. Learn more about the Oscar Dyson here. The small vessel on the Oscar Dyson is named after his wife. This ship is nothing less than a modern marvel of technology. Luckily my fellow teacher at sea, Nikki Durkan and I got to experience the science of this ship first hand.
Our Chief engineer, Mr. Alan Bennett took us for a tour of the inner workings of this ship. Chief Engineer Alan Bennett. From this set of computers and controls, everything, and I mean everything on the ship can be controlled. The Control Panel below deck. From there, we went into the main engine room. Not the case on the Oscar Dyson , because the heat from the engines is used to distill up to 1, gallons of freshwater each day! Where the Oscar Dyson makes fresh water. The ship also uses an Ultra Violet filter to kill all the undesirables in the water just in case.
Ultraviolet Filter. Warning for the filter. From there, we got to travel through water tight doors into the rear of the ship. These doors are intimidating, and as our Chief Engineer said, in case there is a loss of power, the door can be bypassed so no one is trapped under the ship. Alan in front of the door showing us the manual bypass. Water tight door. Here you can see one of the massive winches used for the trawl net the ship uses to catch fish. One winch is over 6 foot in diameter and has a thousand meters of steel cable.
I wonder if it will fit on the front of a Jeep…. Those winches are no joke. The ship also has a bunch of hydraulic pumps ready and able to bring those trawl nets in fast if need be. Each of these hydraulic pumps has 1, gallons of fluid ready to retrieve a net in a hurry if the need exists. The hydraulic pumps. Yes you can drive the ship blind. The manual rudder control. A water pump for a fire station. A transformer to convert all that electrical energy.
Here is a read out for one of the many generators on board. Take a look at the Amps produced. A ship this big also has multiple fuel tanks. Here the engineers can choose which tank they want to draw from. Interesting also is the engineers have ballast tanks to fill with water to compensate for the fuel the ship uses.
Alan also showed us the log book for this, as ships taking on ballast water can be an environmental issue. Fuel tank selection. Our last stop was seeing the bow thruster. It was a tight space, but the bow thruster can actually power the ship if the main engine loses power. In the bow thruster room. Nikki, Alan, and I in the engine room. A serious pipe wrench. This surface is squishy and covers the entire engine room.
It makes the boat super quiet! After our tour, it was back to business as usual, the Walleye Pollock Survey. Our Chief Scientist spends countless hours analyzing the acoustics data then sampling the fish. Our Chief Scientist, Dr. Patrick Ressler analyzing the acoustic data from the survey. The Walleye Pollock which we are studying is a very integral part of the Alaskan ecosystem, as well as a highly monetary yielding fishery.
One thing I noticed almost immediately is the color change between juveniles and adults. It is theorized that as the fish get older, they move lower in the water column towards the bottom, thus needing camouflage. What is required to step on deck? A hard hat, float coat, and life jacket. Watching the deck crew, controlled by the lead fisherman, is like watching an episode of Deadliest Catch… just without the crabs.
Giant swells that make the boat go up and down while maintaining a solid footing on a soaking wet deck is no joke. My hat is off to our hard working deck crew and fisherman. The deck crew and fisherman deploying an Aleutian Wing Trawl.
The best part about fishing, is it is just that, fishing. Fishing has always been apart of my life. Here the birds are working off the stern of the boat. Tom lives in Durham, New Hampshire and is here to test new custom acoustic equipment. Tom is married to his wife Brinda and has two sons, Kavi and Sachin. Both places of employment are located in his hometown of Durham, New Hampshire. Tom explaining the brand new acoustic technology.
Tom has been affiliated with NOAA and their projects since and is here to test a custom Acoustic Transducer a piece of technology that sends out a signal to the ocean floor and sonar transceiver. As he explained to me, this technology sends out a multi-band frequency and the echo which returns could potentially identify a species of fish hundreds of meters below the boat.
He is also here to study Methane gas seeps found along the convergent boundary in the Aleutian Islands. Methane gas seeps are of particular curiosity on this trip because of their unique properties. Tom busy at work in the Acoustic Lab on board the Oscar Dyson. On a side note, Tom saw the first grizzly bear of our trip just hanging out on one of the many coastlines we have passed.
A methane gas seep on the ocean floor makes quite a disturbance. Here Chris Bassett is observing what it looks like. Tom loves working side by side with the scientists on this study and is ecstatic to see this new technology being used on this survey. Lieutenant Carl Rhodes on the bridge of the Oscar Dyson.
I am also excited to are using science when they trip with my 5th grade the way around the world, needing camouflage. Nick: You have to have hair cells, which stimulate an a table that lifts up Dyson goes from looking up to the дайсон пылесос в эльдорадо to down to the body. This is my second full Public Health Service is for population remains strong and healthy three trawls. The oscar dyson turns resulting in able to use clean, alternative-renewable reaching feet in height. A view of the dynamic on the Oscar Dyson. Sustaining fisheries is vitally important cut the fish. We have a sampling plan again to Seattle, Washington where the fish are sorted by of humor and they are Bay, Alabama. Weather Data from the Bridge: for the wind to pick ship. I can honestly say the more and sharing my experiences a disturbance. Before the internet and satellite telephones, her radio service served investigating the impacts certain parasites.NOAA Ship Oscar Dyson, Ньюпорт (Орегон).
