Another exciting couple of days at sea here on the Corwith Cramer!
Yesterday we had a sketching workshop led by Sketch Biologist and Williams-Mystic alumna Abby McBride (F’04). Abby’s work as a science communicator combines her love of biology and sketching. Even students who were unsure at first were soon eagerly sketching sails, coils of rope, and each other. Following class, B watch gathered with Abby for a small group tutorial, where they continued sketching and discussing the uses of drawing and careful observation.
Wednesday night was another starry one. Ever since we turned to head toward the Virgin Islands, the Southern Cross had come into view. The watch schedule here — each of the three watch groups spends 6 hours on watch followed by 12 hours off — means that students get to see different times of day and night throughout the voyage. Though we take turns sleeping, the ship never sleeps; at least one eight– to nine-person watch group is always awake to steer, look out, sail, and collect scientific data.
Today, we completed our third and final Science Super Station. At 700 meters, today’s station was shallow enough to get a sample of cold, tan mud from the ocean floor. We also collected water from 12 different depths in the ocean, which we are currently analyzing for pH and chlorophyll-a, among other properties.
During yesterday’s science station, we lowered Styrofoam cups and a wig head down more than a mile (1,682.3 m) while collecting temperature and salinity data. We had carefully decorated the cups with sunsets, zooplankton, and mythical creatures before sending them down. Afterward, the cups were the size of thimbles due to the pressure in the deep sea. Some of our cups may even be placed on display at Mystic Seaport Museum’s upcoming exhibit on sailor art, which will open in June 2020!
Today’s academic class was an interdisciplinary look at “Ways of Knowing” taught jointly by Lisa, Kelly, and Abby. We examined what it means to “know” something: Who has knowledge? How is knowledge acquired and how we use it? Each instructor offered examples from her experiences within her discipline. (The opening discussion question: “Before underwater cameras, how did we know what a live whale looked like?”) The class was interactive, with a kinesthetic exercise, drawing, and several discussions.
During class, we were fortunate to observe an enormous bait ball bobbing off the port side of the ship, first spotted by the swarm of seabirds (brown boobies and shearwaters). As we approached, we could see fish flying and flopping and feasting on the tiny baitfish, and even a shark cruising by to eat the bigger fish. The food web in action!
In nautical science class, we practiced gybing several times. A gybing ship shifts its sails so as to trace a zig-zag pattern in the direction of the wind — a pattern that allows it to gradually chart its course in the desired direction using only wind power to move forward. Just a few days ago, all the terms and tasks that go into gybing felt so foreign. Now, these maneuvers are starting to feel natural. We are starting to feel at home.
You can follow the Cramer’s progress here:
Please note that vessel tracking information is NOT updated continuously and the Cramer isn’t always able to provide updated location information. (Good reception isn’t a guarantee at sea!) If you notice that the Cramer appears to be in the same location for an extended period of time, it simply means the website has not yet been updated.
