Arts and crafts day on the Knorr

Yesterday was officially arts and crafts day on the R/V Knorr. We had a very specific project: decorate styrofoam cups.

If you?re wondering why, just hold on a minute. First, some pictures of our beautiful cups:

Cups and their makers.

So the reason we all made a couple of decorated cups has to do with pressure in the ocean. As you get deeper and deeper in to the ocean, it gets darker, colder and denser. The deeper you go, the more pressure crushes in on you. Organisms that live deep in the ocean have special adaptations to survive such pressures. Submarines have to be built with reinforced sides to stay intact. Styrofoam cups, well, they don?t do so well.

We tied the cups to the CTD, plopped it in the water, and sent it down. All the way down to 2,500 meters. A lot of times they send it deeper, but where we are that?s about as deep as we can go. As they go down, the cups get crushed, and when they come up, they look like this:

Cool right? Here?s a before and after shot:

?

One atmosphere is about 14.6 pounds per square inch of pressure. Every time you go down 10 meters, you add one atmosphere. So at 2500 meters you?ve got 3650 pounds per square inch coming at these cups from all sides. You?d squish too.

Apparently this is somewhat of a tradition on oceanographic cruises. One guy on board, Peter Lee, says he has about 20 shrunken cups. Anton, who works on the Knorr, says he has about ?a half a million.? He used to use them as Christmas presents. In the old days of sailing they had shrunken heads, we?ve had to settle for shrunken styrofoam cups. At least customs won?t take these away from me.

During this trip, I?ll be answering your questions about the science, this boat, and life onboard. Want to know how we search for plankton, why we?re here, or what the food is like? Just ask me! And if you?re wondering how I got here, check out the groups that made this adventure possible: Mind Open Media and COSEE NOW.
