As a teacher, I am constantly involved in professional development activities which could take the form of a presentation, workshop, seminar, book study or immersive educator experiences such as NOAA Teacher at Sea. At the end of each offering, whether I am required to or not, I take it upon myself to consider its impact on me as an educator and reflect upon how the take-home messages will impact my students. Because of the wide-ranging facets and extensive learning opportunities provided by the Teacher at Sea cruise, I took particular interest in drafting my reflections. It was an experience that I spent an inordinate amount of time thinking about and an activity that I looked forward to reflecting upon. However, just to be clear, reflections in my definition is not a concise and cogent summary of the activities that occurred while on cruise. This is what was presented in each prior post of my blog. Rather, my reflection represents a “30,000-foot overview” of my interpretation and evaluation of the experience.
As I prepared the text for the reflections of my Teacher at Sea cruise, I opted to adapt the words to photos of scenic views taken from onboard the R/V Tommy Munro and threaded the images together in a video presentation.

As I gaze in any direction at the seemingly endless volumes of ocean, I see questions… questions to be answered and answers to be questioned, questions to be formed and questions to be researched, questions that will inspire one to learn beyond imagination… with answers that will foster an understanding deep within… of the unexplored frontier of marine life below the water’s surface. Questions to me present an opportunity… to celebrate what we know and to stimulate our quest to discover what we don’t. As a NOAA Teacher at Sea, I will return to the classroom with… questions waiting to be answered, answers waiting to be investigated, and hopefully career paths in ocean sciences waiting to be pursued.
I hope you enjoy the video and for my educator colleagues, please consider taking advantage of this “once in a lifetime” opportunity for you and your students.
In wrapping up the final post for this blog, I would like to continue with the final installment of my exercise of the Ocean Literacy Framework and ask you to respond to three questions about the seventh essential principle (The ocean is largely unexplored), presented in a Padlet accessed by the following link:
Remember, there are no right or wrong answers – the questions serve not as an opportunity to answer yes or no, or to get answers right or wrong; rather, these questions serve as an opportunity not only to assess what you know or think about the scope of the principle but also to learn, explore, and investigate the demonstrated principle. If you have any questions or would like to discuss further, please indicate so in the blog and I would be glad to answer your questions and initiate a discussion.

Nome, Alaska: (8/25/18) Departing temperature 51 and cloudy
Contoocook/Hopkinton, NH: First day of school Tuesday (8/28/18)- Forecast 94 degrees Mostly Sunny (did I mention we don’t have air conditioning in New Hampshire?)
Ashore and I am headed back to NH
After completing our work in our most Northern point stop, we steamed back to Nome with just one more set of measurements on the way back, then had one final day of travel. It was sunny on the first day back but rougher seas than we had experienced thus far.
There were estimated 8-12 ft waves and some even larger that crashed over the Healy. To the right is a picture that I captured of the bow during this portion of our trip and the rocky seas. Keep in mind that for most of the day we were lucky enough to be on the front deck of the boat! After the waves calmed we were in the fog for most of the way home so spotting more whales and seals was difficult.
In short, the trip was a success with the tremendous amount of data collected. This data will now be analyzed by scientists and students and I hope to see some scientific papers on this research in the future. Here is a list of what was done on this trip:
In addition to the above, there were many (I don’t have the exact count) Van Veen Grabs. I did not get to explain these in a blog so here is a quick overview. Scientists that study the sea floor, including the top layer of soil called the benthic zone, use a VanVeen Grab Sampler pictured below. It is lowered to the sea floor and then the scissor-like arms close the catch capturing a hunk of the sea floor and everything that was living on it. Once on shore the catch is rinsed through a sieve until all the clay is rinsed away leaving just the organisms that were living there (such as mollusks, clams, starfish, worms and more) and a few stones.
The scientists on the team also took HAPS core samples. I did not get to explain these in a blog so here is a quick overview. The HAPS corer, pictured below, is a gravity corer. This is a device that is lowered to the sea floor and then the weight of the device settles into the sea floor. When the HAPS corer is lifted, the bottom of the tube containing the cut into sediment closes, trapping the sample. These samples are then stored in clear tubes as shown in the picture. Scientists can examine sentiment layers to gain a better understanding of the sea floor at that location by studying the sedimentary layers.
HAPS core samples stored in tubes
All this above data has been copied and specimens are stored. The primary focus of this trip was to gather data and now the long process of analyzing and communicating the results will begin.
This was such a great opportunity for me to meet so many different scientists and to both observe and assist the varied scientific studies occurring all at once. I needed all three weeks to get a handle on it all. I am looking forward to sharing what I have learned with my Maple Street School students back in New Hampshire and following the scientific studies as they move forward. Thanks to NOAA, Maple Street School, everyone else that allowed this learning opportunity to happen. It was a summer I will not forget experiencing a ship crash through ice in August! I leave you with some of the reflections of the birds I captured on those calmer days at sea.

Science and Technology Log
I’m going to take you back in time to July 13, a day when a once-in-a-leg event took place. We awoke that morning to a strong breeze blowing NOAA Ship Fairweather towards the dock in Nome. Normally a breeze blowing a docked ship is fine, but that day was the start of our long awaited departure to Point Hope! 0900 was quickly approaching, and Ensign Abbott was excited for his first opportunity as conn during an undocking process! With XO Gonsalves at his side for support, he stepped up to the control center outside the bridge on the starboard side.
As you may or may not know, taking the conn is no small feat. “Conn” is an old name for the conning officer, or controller of the ship’s movement. The conning officer used to stand on the conning tower, an elevated platform where the ship’s movement could be monitored. Although the conn no longer stands on a conning tower, the name and role remain the same. The conn makes commands to the rest of the ship and, during docking and undocking, controls the two engines, two rudders, bow thruster, and the lines attaching the ship to the dock. Each part causes the ship to move in specific way and has a very important function in undocking.
ENS Abbott did a great job deciding which parts of the ship to maneuver which way and when. The process was so technical that I cannot begin to describe it. However, the persistent westerly wind just kept drifting the ship back into its docking station. Every time we got the ship positioned the way we wanted, it would push right back into its starting place. The situation turned hazardous because we had a giant barge docked in front of us, a fishing vessel docked behind us, and the wall of the dock to our starboard side. The only direction we could go without danger of crashing into something was to the left. Unfortunately you cannot move a ship side to side very far without forward or backward movement, so there are strategies for moving the ship in a forward to backward motion while simultaneously moving left or right.
In our situation, the best thing to do was to slowly back the ship out while swinging the stern end into the harbor. Once out enough to account for the westerly wind, the engines could push forward and the ship could safely exit the harbor. Unfortunately all did not go as planned and when the engines went forward, the wind pushed the ship so far towards the dock in a short amount of time that the stern narrowly missed a collision with the wall of the dock! It was a close call! The conn was unlucky in the fact that he was assigned control of the ship during weather conditions no sailor would elect, but he did his best and it was a great learning lesson for everyone!
Fast forward to July 19. The members of the NOAA Corps new to ship docking and undocking had a brief in the conference room. They discussed all of the physics involved in the undocking from the week prior, debriefed the challenge the wind posed, and reviewed the different types of maneuvers for undocking. Then they shifted the conversation to planning for the next day’s docking maneuver. XO Gonsalves, with a vast array of unique skills in his toolbox, turned on a PlayStation game that he created for his crew to practice docking and undocking! Docking a ship is a skill with the unique problem that you cannot simply practice it whenever you want to. The only attempt offered to the crew during this leg was on the morning of July 20. It was a “one and done” attempt. Lucky for them, XO thought outside the box! With the video game, they could practice as often as they wanted to and for as long as necessary to get the skill down.

The challenge presented to the crew was to dock and then undock the boat seen in the photo above eight different times with varying obstacles to work through. Examples of obstacles were having a small docking space, turning the boat around, and wind adding a new force to the boat. Three controllers were needed for the job. The first controller, and the little tiny person at the front of the boat, controlled the bow thruster. The bow thruster could push the boat left or right in a jet propulsion-like manner. Using the bow thruster on the port side pushed the boat right, and using the bow thruster on the starboard side pushed the boat left. The XO also assigned this person the roll of the conn, so they had to call out directions to everyone playing the game. The next person controlled the engines. This was a difficult task because there is a port and a starboard engine, and each engine can go forward or backward. The conn could give a simple order like “all ahead” or a more difficult order like “port ahead, starboard back” (trust me, that one is not easy). The last person controlled the rudders. The rudders worked in unison and could be turned right or left. The rudders can be fine-tuned in reality but in the game, due to the controller’s limitations, we used the commands of “half rudder” and “full rudder” to choose how significantly the rudders should be turned. You can see a small clip of the game in action below. Turn up the volume to hear the conn. As a reminder, the Corps members participating are learning the process, so you may hear a variety of commands as they fine tune their vocabulary to use more specific language.
On the morning of July 20, the docking process was smooth with no surprise forces at play on the ship. The NOAA Corps did an excellent job with the maneuver. As soon as we thought we would get a chance to relax, a food order arrived with 2,700 lbs of food that needed to be hauled from the top deck of the ship down to the bottom. Horizontal forces affecting the ship were no comparison to the vertical force of gravity pulling all those boxes down towards Earth, but we used an assembly line of 20 people passing boxes down the stairwell and we all ended the day with a good workout!
It seems fitting to begin my last blog with the story of undocking the Fairweather in Nome at the start of the leg. This is not the end of my Teacher at Sea journey but the start of my work, integrating my personal experience into something relevant for my students in a physical science classroom. Since returning home, I completed my first media interview about my time at sea. Ironically teaching others about myself led to my own epiphanies, namely refining my “why” to becoming an educator. I told Amanda, my interviewer, how I spent my childhood soaking my shoes in ponds trying to catch frogs, harvesting new rocks for my shoe box collection under my bed, and following the streams of water every April when snow melted away. I grew up with a curiosity for all things natural and scientific. Science classes were simply an outlet for my inquisitive mind, so it was easy to be engaged in school. Below are a few photos of me in high school, memories of times that inspired my love for the ocean. That natural wonder, excitement, curiosity I had for the world around me as a child and young adult…that’s what I want to instill in my students. My experience on the Fairweather helped me find new tools for my “teaching toolbox” and new ideas for my curriculum that I hope will inspire more students to become curious about their worlds. You’re never too old to discover the intrigue of the natural world. When you begin to understand that the purpose of science is to explain what we observe, your desire to uncover the secrets will grow!

The ability of a ship to make 3,000,000 lbs of weight float on water, that is intriguing. The idea of using sound waves, something we interact with constantly on land, under the water to map what we cannot see, that is amazing. Collecting an array of data that, to the untrained mind seem unrelated, and putting them together into a chart used by mariners all over the world, that is revolutionary. NOAA hydrographic ships connect science and the economy in a way not dissimilar to how I hope to connect education and career for my students. This experience inspired me in ways beyond my expectations, and I cannot wait to share my new knowledge and ideas in my classroom!
Did You Know?
The Multibeam Echosounder on the ship obtains ocean depths accurate to 10 centimeters. The average depth of the ocean is 3,700 meters, or 370,000 centimeters, according to NOAA. That is an average percent accuracy of 99.997%!

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.
