DAY 6: HAVE A LOOK AT WHAT PRESSURE CAN DO!
04.07.2008 This is a picture of two Styrofoam coffee cups. One came out of the G.O. Sars galley. The other was attached to the ROV when it went down 2500 meters (about 8200 feet).

We watch the sea very comfortably however, in a viewing room. The camera attached to the ROV, under the skilled hands of trip videographer Stein Hitland, takes wonderful movies; it is our "eye" on the deep. The video image is projected on a large flat screen TV in the "board" room. Watching it is like being in the audience of an IMAX, except that it is in real time, and we teachers have the benefit of scientists in the room with us who can identify what we see. The pictures today came from a pillow lava field. Below you will see a picture of pillow lava. This is a group of fairly young lava - meaning it was formed, as was explained to us, anywhere from ten to a thousand years ago; probably however it is between one hundred and two hundred years old. Pillow lava forms when lava bubbles up from underground, and hits the cold sea. The thin layer of sediment here is what lets us know the young age of the rocks.
