NASA Completes 2010 Voyage to Arctic Ocean
08.06.10
 
On July 26, NASA concluded the 2010 portion of the Impacts of Climate change on the Eco-Systems and Chemistry of the Arctic Pacific Environment (ICESCAPE) project, NASA’s first dedicated oceanographic field campaign. Researchers with the project are sampling the physical, chemical and biological characteristics of the ocean and sea ice. The bulk of the research takes place in the Beaufort and Chukchi seas in summer of 2010 and fall of 2011 from the U.S. Coast Guard Cutter Healy.

Cut 1 00:21 – “If there's a lot of algae the ocean is green, and when there's not much algae the ocean is blue. And that's important from NASA's point of view because NASA can build instruments that fly on spacecraft and observe the global oceans in a way that we actually can map out the color of the ocean. These are called ocean-color satellites.”

Cut 2 00:29 – “So as an oceanographer I'm used to finding phytoplankton just floating in seawater, a lot of my work is done in mid-latitude or tropical areas. But in the Arctic you find phytoplankton in other areas, they can be embedded in the bottom of the ice, they can be in the melt ponds on top of the ice, so one of the goals of this mission for me is to get as many samples of phytoplankton from these different environments both in and out of the ice.”

Cut 3 00:20 - "So from a couple optical measurements, from a lot of thickness measurements, from some of the melt pond measurements, we put that all together and we get a two-dimensional map of how much light gets through at different wavelengths, how much of that light is what's called photosynthetically available radiation, which is the stuff the little algae like to eat.”
