Greetings from 83N, 150W.
In honor of being at our farthest point north, we sent Styrofoam cups down with the Rosette to 2710 meters. What do you think happens to a cup down there, with the weight of all that water on it? See the end of this post to check your thinking.
We also tossed out our last set of drift bottles on the helo deck.
After sampling at this station, we are heading southeast along 140 latitude.
Styrofoam cups at 2710 meters are subjected to the intense pressure of the water column above, and the air above that, and the water all around it. Styrofoam is a lattice filled with air.
Our mascot Lulu is now sporting a shrunken head.
I decorated 5 cups, one each for my family and one to thank my supporters of this great adventure: PolarTREC, WHOI, The LSSL Scientists and Crew, Durham Academy and my family.
