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.
Using a probe to measure water temperature, salinity, and dissolved oxygen
Looking happy as the probe descends
Using a claw-like apparatus to sample sediments
The sediments collected were clay-based and described as “very good for your skin”
Fellow SSF Vincent obviously took that above comment to heart as he examines the critters under the microscope
Tubeworm that was extracted from the mud
It usually protecs its soft, fragile body within this hard casing, but we took it out for examination
Other cool critters
Using a net to catch ctenophores, a bioluminescent, jellyfish-like creature that glow up when you accidentally bump into them during night swims
Cute ctenophores. 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. Perhaps 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!
Out and about and having a grand old time
Overall, it was a beautiful day spent with a wonderful crew!
