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!
Personal Log
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%!
