R/V Tioga

The Summer Student Fellowship program includes a day trip on the research vessel Tioga to show us various sampling techniques used in oceanography. The day trip starts out at 8:30am and sailed out westward to Buzzard’s Bay. Many students had a chance to have a hands-on experience on using one the sampling equipments.

Ctenophores are very cute but definitely prettier at night when they bioluminesce when you accidentally bump into one. Since they are so abundant, the crew encouraged us to taste them and they tasted exactly like one would expect - a bag of salty seawater. Guess these guys are pretty good at keeping equilibrium with the seawater to minimize the energetic costs of osmosis

Our final activity was learning how to navigate by measuring angles of three landmarks. This gave us three lines on this map that located us to the area where they crossed. The GPS (star) confirmed that we were right on!
