Personal Reflection

Wow! What an incredible experience! When I was first accepted into this program I knew that it would be great and I knew that I was going to be working on research, but I feel like I ended up getting way more than I had expected. While filling out my application for the NOAA Teacher at Sea program we were given the opportunity indicate a preference for locations and types of research. I indicated that I would have been happy with any of them, but I was honestly hoping to be on a fisheries cruise, and my first choice of location was Alaska. That’s exactly what I got! I could not have picked a more perfect match for myself.

When I first received my specific cruise offer to join NOAA Ship Oscar Dyson it was pointed out to me that 23 days at sea was a LONG cruise, and I was a little bit worried about being at sea for that long when I had never even slept on a ship like that before. What I didn’t realize, was that the hardest part of this research cruise, would be leaving at the end of it. Saying goodbye to the scientists and friends that I had worked closely with for the past 3+ weeks was pretty tough.

The natural beauty of Alaska, and Unalaska specifically, is breathtaking. I kept saying that I can’t believe that places like that existed in the world and people weren’t tripping over themselves to live there. This is a part of Alaska that very few ever see. I loved getting to explore Dutch Harbor and see some of the beaches and do a little hiking while in port, and seeing the different islands and volcanoes while at sea. I also was incredibly excited to see all of the wildlife, especially the foxes, eagles, and of course, whales.

From the moment that Sarah and Matthew picked me up from the airport, I knew that I was in great company. They immediately took me in and invited me to join the rest of the science team for dinner. Bonding happened quickly and I am so happy that I got to work with and learn each day from Denise, Sarah, Mike, Nate, Darin, Scott, and Matthew every single day. I looked forward to (and now miss) morning coffee chats, and dancing in the fish lab together. I have so many positive memories with each of them, but here are a few: sitting and reviewing and discussing my blogs with Denise, taking photos of a stuffed giraffe with Sarah, go pro fishing (scaring the fish) with Mike, watching Scott identify and solve problems, listening to Darin play the guitar, fishing with Nate on the Bridge, and exploring on land with Matthew. These are just a few of the things that I will remember and cherish about these wonderful people.

I know that it happens in all workplaces eventually, but it’s weird to think that the exact same group of people on the ship will never again be in the same place at the same time because of rotations and leave, and whatnot. I feel very grateful that I was on the ship when I was because I really enjoyed getting to know as many people on the ship as possible, and to have them teach me about what they do, and why they do it.

Not only did I learn about the Scientific work of the MACE (Midwater Assessment and Conservation Engineering) team, I learned so much about the ship and how it functions from everyone else on the ship. Every single time that I asked someone a question or to explain how something works, I was always given the time for it to be answered in a way that was understandable, and meaningful. I learned about: charting and navigation (thanks Aras), ship controls (thanks Vanessa), The NOAA Corps (thanks CO and Sony), ship engines and winches (thanks Becca), fancy ship knots (thanks Jay), water data collected by the ship (thanks Phil)… I could go on and on.

After landing back in port in Dutch Harbor, I got off of NOAA Ship Oscar Dyson and turned and looked at it, and my perception of it had changed completely from the beginning of the cruise. It sounds totally cliché, but it wasn’t just a ship anymore, it was somewhere I had called home for a short time. As I looked at the outside of the ship I could identify the rooms behind each window and memories that I had in that space. It was surreal, and honestly pretty emotional for me. On the last day, once we got into port, my name tag was taken off of my stateroom door and it was replaced with the names of the new teachers heading to sea. It was sad to realize that I really was leaving and heading home. It’s weird to think that the ship will continue on without me being a part of it any longer.

A valuable part of the NOAA Teacher at Sea program was me stepping back from being a teacher, and actually being reminded of what it feel like to be a learner again. I was reminded of the frustrations of not understanding things immediately, and also the exciting feeling of finally understanding something and then being able to show and explain it. I loved learning through inquiry and asking questions to lead to newer and better questions. These are the things that I am trying to implement more in my classroom.

While on the ship I was able to come up with 3 new hands on activities that I will be trying out in my classes this year. This is in addition to the one that is directly related to my research. The new labs that I have created will help me to focus my efforts and give my students the skills that they will benefit from in the future. I am also even more excited to go and pursue my Master’s Degree in the near future than I was before, even though I am more confused on what to go back to school for.

I love being able to participate in research in addition to teaching. I really feel like it makes me a better teacher in so many ways. It really reminds me what is important to try and teach my students. In the world of Google searches and immediate information, learning a bunch of facts is not as practical as learning skills like how to test out a question, collect data, and share knowledge learned. I am so grateful for this opportunity and I really hope that I am able to continue to find other research experiences for myself in the future. I would love to be able to further my research experiences with MACE by visiting them in Seattle, and I would be happy to hop back on the Oscar Dyson, or another NOAA ship, at any time (hint, hint, wink,wink). Thanks for the memories.

Science and Technology Log

On this leg of the Research Cruise in the Eastern Bering Sea I will be helping a team of NOAA scientists collect data about a fish species called Pollock. The data that are collected will help to set the limits for how much pollock the fishing boats are allowed to catch. The data also allow scientists to track the populations of the pollock to look for patterns. For additional information on Pollock, visit the NOAA fisheries website here.

During the survey, acoustic (sound) signals will be sent into the water by transducers at different frequencies and these acoustic signals will bounce off of the objects in the ocean and bounce back to the ship where the echoes will be picked up by the transducers. The data collected from each echo is presented visually to the science team. When we reach a spot where a lot of the acoustic signals returning to the boat indicate the presence of fish, a trawl sample will be taken at that location. A trawl survey includes putting a large net into the water and scooping up a sample of all of the living things in that location. Once the trawl haul is brought onto the boat, it is taken to the fish lab where the fish are identified and measured.

The area being surveyed is the Eastern Bering Sea and for this study is divided up into 28 different transects have been mapped out and are spread 20 nautical miles apart. We will start at northern point of the first transect and travel south until we reach the bottom of it. Once we reach the bottom of the first transect we will travel 20 nautical miles west to the southern tip of the second transect. We will then travel north along this second transect until we reach the top and then travel the 20 nautical miles west until we reach transect 3. This will continue throughout my time on the ship, and on the 2 other legs of this journey. On this first leg of the research cruise, the aim is to survey and sample from 16.3 of the transects which will total a journey of 2627 nautical miles on the transect lines.

According to the NOAA National Ocean Service Website, “A nautical mile is based on the circumference of the earth, and is equal to one minute of latitude. It is slightly more than a statute (land measured) mile (1 nautical mile = 1.1508 statute miles). Nautical miles are used for charting and navigating.”

It was a long trip getting to Dutch Harbor, Alaska, but it has already been worth it! I am on the Island of Unalaska, which is a part of the Aleutian Islands of Alaska. The main port city is called Dutch Harbor, or commonly just “Dutch”. This is such a beautiful place that I probably never would have seen otherwise. There are mountains filled with grasses, berry bushes, and wild orchids as well as snow-topped peaks and natural waterfalls. There are bald eagles everywhere and foxes that are so fluffy they almost appear to be dogs from far away. Looking into the water you can see a few scattered otters floating on their backs and the occasional harbor seal.

OSI Morning photo — This photo was taken from the bow of NOAA ship *Oscar Dyson* at port in Dutch Harbor, AK.

As soon as I landed in Dutch, I was greeted by two of the scientists that I will be working with, Matthew and Sarah. They took me to NOAA Ship Oscar Dyson to drop off my luggage before we all went out to dinner. I was pleasantly surprised to find out that I actually had my own stateroom. Due to the number of female scientists and us being on the same work shift, we were both able to have our own rooms. The rooms are so much nicer than I had anticipated them to be! The mattresses are comfortable, I have a desk space, there’s a television (that I will probably never watch) and I have my own bathroom as well.

After we had dinner and returned to the ship, I went on a mini hike with one of the members of the science team and we went to view this amazing natural waterfall. You wouldn’t know it was there if you weren’t looking for it. There is so much more that you can do when the sun is up for most of the day. At 11:30pm (the latest i’ve stayed up so far) it is still light outside. There are so many clouds that the sky looks pretty grey, and there are a ton of clouds, often hiding the tops of the mountain peaks.

The next morning I woke up and went for a nice long walk along Captain’s Bay and sat and had coffee on the rocks and just admired the incredible view. It is so much more beautiful here than I had imagined. Later a few of us went for a drive around the island and a few people surfed in the ocean, but I wasn’t brave enough to get in the cold water this time.

Since we will be on the ship for a while (23 days) we stopped at the grocery store to bring a few things onboard that we want to have in addition to our regular meals prepared on the ship by the stewards. I decided that I wanted to bring some fresh fruit, not realizing that I would be paying way more than I expected for them! Everything is expensive here!

Expensive fruit — $26 dollars worth of fruit in Dutch Harbor, AK.

Did You Know?

Even though we think of Bears and Moose being found all over Alaska, they are not found on the Island of Unalaska at all!

Science and Technology Log: Abiotic Factors in the Bering Sea

Ecosystems are made up of biotic and abiotic factors. Biotic is just another word for “stuff that is, or was, alive.” In a forest, that would include everything from Owl to Oak Tree, from bear to bacteria, and from fish to fungi. It includes anything alive, or, for that matter, dead. Keep in mind that “dead” is not the same as “non-living.”

Salmon and Black-Legged Kittiwake — The salmon and the black-legged kittiwake are both biotic members of the sub-arctic ecosystem.

“Non-living” describes things that are not, cannot, and never will be “alive.” These things are referred to as “abiotic.” (The prefix a- basically means the same as non-). Rocks, water, wind, sunlight and temperature are all considered abiotic factors. And while the most obvious threat to a salmon swimming up river might be the slash of a bear’s mighty claw, warm water could be even more deadly. Warm water carries less dissolved oxygen for the fish to absorb through their gills. This means that a power plant or factory that releases warm water into a river could actually cause fish to suffocate and, well, drown.

Bering Panorama — A 90 degree panorama of the Bering Sea from atop the Oscar Dyson. I’d show you the other 270°, but it’s pretty much the same. The sea and sky are abiotic parts of the sub-arctic ecosystem.

Fish in the Bering Sea have the same kind of challenges. Like Goldilocks, Pollock are always looking for sea water that is just right. The Oscar Dyson has the tools for testing all sorts of Abiotic factors. This is the Conductivity Temperature Depth sensor (Also known as the CTD).

CTD Deployment — Survey Technicians Allen and Bill teach me how to launch The Conductivity Temperature Depth Probe (or CTD).

The CTD sends signals up to computers in the cave to explain all sorts of abiotic conditions in the water column. It can measure how salty the water is by testing how well the water conducts electricity. It can tell you how cloudy, or turbid, the water is with a turbidity sensor. It can even tell you things like the amount of oxygen dissolved in the ocean.

To see how abiotic factors drive biotic factors, take a look at this.

I know, you may want to turn the graph above on its side… but don’t. You’ll notice that depth is on the y-axis (left). That means that the further down you are on the graph, the deeper in the sea you are. The blue line represents the water temperature at that depth. Where do you see the temperature drop?

Right… The temperature drops rapidly between about 20 and 35 meters. This part of the water column is called the Thermocline, and you’ll find it in much of the world’s oceans. It’s essentially where the temperature between surface waters (which are heated by the sun) and the deeper waters (typically dark and cold) mix together.

OK, so you’re like “great. So what? Water gets colder. Big deal… let’s throw a parade for science.”

Well, look at the graph to the right. It was made from another kind of data recorded by the CTD.

Fluoresence: Another depth-oriented graph from the CTD… the green line effectively shows us the amount of phytoplankton in the water column, based on depth.

The green line represents the amount of fluorescence. Fluorescence is a marker of phytoplankton. Phytoplankton are plant-like protists… the great producers of the sea! The more fluorescence, the more phytoplankton you have. Phytoplankton love to live right at the bottom of the thermocline. It gives them the best of both worlds: sunlight from above and nutrients from the bottom of the sea, which so many animals call home.

Now, if you’re a fish… especially a vegetarian fish, you just said: “Dinner? I’m listening…” But there’s an added bonus.

Look at this:

CTD Oxygen — Oxygen data from the CTD! This shows where the most dissolved oxygen is in the water column, based on depth. Notice any connections to the other graphs?

That orange line represents the amount of oxygen dissolved in the water. How does that compare to the other graphs?

Yup! The phytoplankton is hanging down there at the bottom of the thermocline cranking out oxygen! What a fine place to be a fish! Dinner and plenty of fresh air to breathe! So here, the abiotic (the temperature) drives the biotic (phytoplankton) which then drives the abiotic again (oxygen). This dance between biotic and abiotic plays out throughout earth’s ecosystems.

Another major abiotic factor is the depth of the ocean floor. Deep areas, also known as abyss, or abyssal plains, have food sources that are so far below the surface that phytoplankton can’t take advantage of the ground nutrients. Bad for phytoplankton is, of course, bad for fish. Look at this:

The Cliff and the Cod — The blue cloud represents a last grouping of fish as the continental shelf drops into the deep. Dr. Mikhail examines a cod.

That sloping red line is the profile (side view of the shape of the land) of the ocean floor. Those blue dots on the slope are fish. As Dr. Mikhail Stepanenko, a visiting Pollock specialist from Vladivostok, Russia, puts it, “after this… no more Pollock. It’s too deep.”

He goes on to show me how Pollock in the Bering Sea are only found on the continental shelf between the Aleutian Islands and Northeastern Russia. Young Pollock start their lives down near the Aleutians to the southeast, then migrate Northwest towards Russia, where lots of food is waiting for them.

Pollock Distribution — Alaskan Pollock avoid the deep! Purple line represents the ocean floor right before it drops off into the Aleutian Basin… a very deep place!

The purple line drawn in represents the drop-off you saw above… right before the deep zone. Pollock tend to stay in the shallow areas above it… where the eating is good!

Once again, the dance between the abiotic and the biotic create an ecosystem. Over the abyss, Phytoplankton can’t take advantage of nutrients from the deep, and fish can’t take advantage of the phytoplankton. Nonliving aspects have a MASSIVE impact on all the organisms in an ecosystem.

Next time we explore the Biotic side of things… the Sub-arctic food web!

Personal Log: The Order of the Monkey’s Fist.

Sweet William, a retired police officer turned ship’s engineer, tells the story of the order of the monkey’s fist.

William and the Monkey's Fist — Sweet William the Engineer shows off a monkey’s fist

The story goes that some island came up with a clever way to catch monkeys. They’d place a piece of fruit in a jar just barely big enough for the fruit to fit through and then leave the jar out for the monkeys. When a monkey saw it, they’d reach their hand in to grab the fruit, but couldn’t pull it out because their hands were too big now that they had the fruit in it. The monkey, so attached to the idea of an “easy” meal wouldn’t let go, making them easy pickings for the islanders. The Monkey’s Fist became a symbol for how clinging to our desires for some things can, in the end, do more harm than good. That sometimes letting go of something we want so badly is, in the end, what can grant us relief.

Another story of the origin of the monkey’s fist goes like this: A sea captain saw a sailor on the beach sharing his meal with a monkey. Without skipping a beat, the monkey went into the jungle and brought the sailor some of HIS meal… a piece of fruit.

No man is an Island. Mt. Ballyhoo, Unalaska, AK

Whatever the true origin of the Order is, the message is the same. Generosity beats selfishness at sea. It’s often better to let go of your own interests, sometimes, and think of someone else’s. Onboard the Oscar Dyson, when we see someone committing an act of kindness, we put their name in a box. Every now and then they pull a name from the box, and that person wins something at the ship store… a hat or a t-shirt or what have you. Of course, that’s not the point. The point is that NOAA sailors… scientists, corps, and crew… have each other’s backs. They look out for each other in a place where all they really have IS each other.

And that’s a beautiful thing.

Mission: Annual Walleye Pollock Survey

Date: July 16, 2014

Hello from beautiful Southern Ohio! My name is Kacey Shaffer and it is an honor to be an NOAA Teacher at Sea for the 2014 Field Season. I am thrilled to be sharing this once-in-a-lifetime opportunity with you. In a few days I’ll be flying across North America to spend nineteen days aboard the NOAA ship Oscar Dyson. Our mission will be to assess the abundance and distribution of Walleye Pollock along the Bering Sea shelf.

Next month I’ll begin my eighth year as an Intervention Specialist at Logan Elm High School in Circleville, Ohio. I teach Biology and Physical Science resource room classes and also co-teach in a Biology 101 class and Physical Science 101 class. Three summers ago I was able to participate in Honeywell’s Educators at Space Academy, held at the U.S. Space and Rocket Center in Huntsville, Alabama. That experience enabled me to bring a wealth of information and activities back to my students and colleagues. Because I had such a wonderful experience at Space Academy, I knew I would soon be seeking out other opportunities to perform hands-on work and gain knowledge not available in my geographic area. I was very excited when I found the NOAA Teacher at Sea program and applied immediately. When the congratulatory email arrived I acted like a little girl on Christmas morning, jumping up and down and squealing!

In 2011, I attended Honeywell’s Educators at Space Academy. For our first team mission, I served as CapCom. I was the communication link between Mission Control and the shuttle. (Photo credit: Lynn of Team Unity)

Not only do I love adventure that is related to my teaching career, I love adventure in general! Two summers ago I had the privilege of joining one of Logan Elm’s Spanish teachers and four of her recent Spanish 4 graduates on a nine day tour of Spain. We were immersed in culture and history in several cities from Madrid to Barcelona. It was a wonderful experience and I really hope to travel abroad again. Last month the same Spanish teacher escorted four more recent graduates to Puerto Rico for a five day stay. Thankfully she felt I had behaved well enough in Spain to be invited on this trip! Our trip to Puerto Rico was very different from our travel in Spain. We were able to go ziplining in La Marquesa, hiking in El Yunque (which happens to be the U.S. National Park Service’s only tropical rain forest), and kayaking in Laguna Grande near Fajardo. The most amazing experience was kayaking at night in Laguna Grande. Why would you kayak at night? Because that is the home of a bioluminescent bay! You can learn more about this ocean phenomena here. I am very thankful to be able to travel as much as I do!

Last month I kayaked in a bioluminescent bay near Fajardo, Puerto Rico. I shared a kayak with my friend Megan, right. (Photo credit: Luiz, our tour guide)

If I were driving to the Oscar Dyson, it would be about a 5,000 mile trip one way! I’m really glad the journey will be via airplane. I’ll be meeting the ship in Dutch Harbor, Alaska. Does that name sound familiar? Dutch Harbor is the home base of the Discovery Channel’s “The Deadliest Catch.” It is a very small town on one of the many islands that are collectively called the Aleutian Islands. From Dutch Harbor we will sail into the Bering Sea and begin our work. From the information I’ve read, we’ll spend our days gathering information about Walleye Pollock. Through my preparations I’ve gathered this is important because Walleye Pollock is one of the largest fisheries in the world. Why would Walleye Pollock be important to me or my students? This fish is often used in imitation crab or fried fish fillets. We could be eating this species the next time we have fish sticks for supper! For greater detail on Alaskan Walleye Pollock check out the NOAA’s FishWatch page here.

The next time I write to you I’ll be aboard the mighty Oscar Dyson. In the mean time I’ll continue to gather warm clothes and search for a box of seasickness medicine. As I’m packing I may need some advice. If you were leaving home for three weeks, what is the one item you wouldn’t leave without? Remember, I’ll be at sea. My cell phone will be rendered useless and my access to the internet will be limited.

Personal Log

Greetings from Dover, Delaware, the first state to ratify the United States Constitution! My name is Mary Murrian and I teach math and science to a wonderful group of fifth grade students at William Henry Middle School. My journey will begin early in the morning on Wednesday, July 2, 2014. My son, Robert–an upcoming junior at the University of Delaware, is driving me to the Philadelphia airport at 3:00 am in the morning. After transferring planes in Chicago, Illinois and then again in Anchorage, Alaska, I will finally make land at my final destination, Dutch Harbor, Alaska.

If you are a Deadliest Catch fan you will recognize Dutch Harbor as the home base for the popular television show on the Discovery Channel. I will be aboard NOAA Ship Oscar Dyson, a NOAA (National Oceanic and Atmospheric Administration) ship. I have the wonderful opportunity to work with the crew and scientists aboard the Oscar Dyson to research and determine the abundance and health of walleye pollock, one of the largest fisheries in the world. If you have ever eaten fish sticks or imitation seafood, most likely you have tried pollock!

Thanks to the NOAA Teacher at Sea program, I am afforded this wonderful opportunity to work hands-on, learning the science involved in research aboard a NOAA ship. I currently teach a unit on ecosystems, where my students learn about the ecosystem around them and the interrelationships between organisms in an environment focusing on food chains, food webs, and environmental factors that play a role in an ecosystem. This experience will enhance my knowledge of marine ecosystems and the important role the fish play in supporting a healthy and sustainable environment. I look forward to learning and growing through my participation with experts in their field. I want to gather as much information as possible, in order to bring it back to my classroom and share my real life experience with my students this upcoming school year and years to come. What a wonderful way to bring real-life data and experiences to my students.

I have been asked numerous times if I am scared or nervous to be aboard a ship sailing on the Bering Sea. My response, NO! I am thrilled. I cannot wait for my journey to begin. I have cruised to Alaska before, however not as far north as the Dutch Harbor area and I was on a recreational cruise ship. It was beautiful and the scenery was amazing. I never saw ice as blue as I did when we crossed Tracy Arm fjord. A fjord is a typically long, narrow valley with steep sides that are created by advancing glaciers (http://oceanservice.noaa.gov/education/kits/estuaries/media/supp_estuar04_fjord.html). The trip, although freezing, was amazing. I also found out that glacial ice often appears blue because of years of compression gradually making the ice denser over time, forcing out the tiny air pockets between the crystals. When glacier ice becomes extremely dense, the ice absorbs a small amount of red light, leaving a bluish tint in the reflected light (http://nsidc.org/cryosphere/glaciers/quickfacts.html). Super cool!

I look forward to my upcoming experience, a trip of a lifetime. There is more to come, I hope you will continue with me on my journey across the Gulf of Alaska and the Bering Sea! Watch out Alaska, here I come!
