Adrift and Well-Rested
Slept in today until 1100 after a successful evening watch (1900-0100) with my B watch friends. The winds failed us at some point in the night, leaving me rudely awakened by increasingly sultry conditions belowdeck. Finally settling into the lopsided 18-hour watch cycle and succumbing to exhaustion means I can pretty much sleep through anything at this point, and the more I settle in, the more I find I can enjoy the small stuff; the little spark of joy I get every time I go up on deck and see the McLane pump deployed or the Neuston tow picking up samples, or the satisfaction of seeing 15 minutes of tough sail handling pay off as we pick up speed and cut through the waves.

After much heaving, hauling, sweating, and grunting, A Watch set the tops’l on the foremast not too long ago, which means today is our first day sailing with a square sail. The Cramer is making good speed with the sporty wind, especially with the tops’l set, although we are still waiting for a shift in the wind so we can sail East deeper into the Sargasso Sea.

Sleepy But Satisfied
I just got off dawn watch, so bear with me. Dawn watch is from 0100-0700. I was a helper in lab this morning, classifying the different species of Sargassum and identifying 100 animals in the sample of water that we collected at midnight. And guess what? We found a Frogfish (a fish found only associated with floating Sargassum, and nowhere else)!! And an endemic Sargassum crab! Wow. So cool.

Hello world. Welcome to the first and final edition of Katarina and Nadia’s blog.
Today we woke up to a delicious breakfast of eggs, potatoes, and pineapples (Katarina really likes pineapples, while Nadia did not eat any. She prefers potatoes). It was lively and loud as usual in B House because B house is best house, whereas in C House it was peaceful and quiet.

SEA To Host 6th Annual Sargasso Sea Symposium
This one-day symposium is the capstone experience for students from SEA Semester class C-273, Marine Biodiversity & Conservation. The event includes oral presentations of the students’ research findings and policy recommendations to a panel of invited experts, and contributes directly to international effort to protect the Sargasso Sea. Student presentations will be interspersed with related talks given by some of the invited participants. The public is invited to attend. Space is limited.

Off to a great start!
Hello friends and family,
Today was an exciting day on board the SSV Corwith Cramer!
The day started bright and early with 6 am wake-ups for A watch and 6:40 am wake-ups for B and C watches, and it’s been a steady stream of new experiences and important training for the students-turned-crew of class C-273 ever since.

SEA Semester alumna’s marine biological research continues at Amherst
SEA Semester in the News
We’re always interested to hear about the continuing research conducted by recent SEA Semester alumni, so we thought we’d share this report about Taylor Hallowell from The Amherst Student. Taylor sailed with C-266, Marine Biodiversity and Conservation, last spring.
Thoughts on Theses: Taylor Hallowell ‘17
By Jacob Gendelman ‘20; Staff Writer, The Amherst Student
Taylor Hallowell ’17 majors in biology. Her thesis examines the sensory drive hypothesis in cichlid fish that express different retinal genes while living under different colors of light. Professor of Biology Ethan Clotfelter is her advisor.
Q: Can you describe your thesis?
A: The sensory drive hypothesis is essentially that there’s a difference in the environment, [which] leads to sensory divergences, like divergences in animals’ sensory systems. That leads to reproductive isolation, and that leads to speciation. There isn’t a ton of evidence for it right now, but there’s an increasing amount. People are starting to take more of an interest in it. I’m trying to get more data for it. I’m working with cichlid fish, which are really common fish to work with because they’re so easy to breed. I have hundreds of little babies already. I’m making them grow up in extreme light environments. A third of them are only getting red light, a third are only getting blue light, and a third are getting just white light. I’m trying to show that differences in light environment cause differences in the expression of the genes in the retina. That would contribute to the sensory drive hypothesis.
