NASA BEGINS RESEARCH VOYAGE TO ARCTIC OCEAN 

NASA’s first dedicated oceanographic field campaign began last week on a scientific mission to take an up-close look at how changing conditions in the Arctic are affecting the ocean’s chemistry and ecosystems that play a critical role in climate change. The ICESCAPE mission (Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment) will sail into the Chukchi and Beaufort seas for five weeks onboard the U.S. Coast Guard icebreaker Healy.

KEVIN ARRIGO, ICESCAPE CHIEF SCIENTIST, Stanford University, Stanford, Calif

Cut 1 (00:36) - “The purpose of this mission really is to look at the changes that have been going on in the Arctic in the last thirty 30 years, particularly in the last decade and to see how the changes have been impacting the ecology and the changes I am talking about specifically relate to changes primarily in sea ice cover which have diminished by over 20 percent over the last 30 years and we have seen some recent dramatic decreases and we know that it’s having some impact on the biology, but we don’t know exactly what those impacts are.  We would really like to be able to characterize that better than we can today.”

DON PEROVICH, ICESCAPE CO-CHIEF SCIENTIST

Cut 2 (00:36) – The purpose of ICEScape, is, as you are aware the Arctic is changing, the sea ice cover frozen at the top of the world is in declining, there is less and less sea ice every year and that has an impact not just on the ice cover, not just on the physical system, but on the ecology as well.  What we are trying to do at ICESCAPEs is look at the connection between the physical systems and the biogeochemical to see how changes in the physical system impact the biogeochemical of the Chukchi and Beaufort seas.”

KAREN FREY, ICESCAPE SCIENCE TEAM LEADER

Cut 3 (00:17) - “Sea ice is declining because of climate warming.  We are seeing warmer air temperature, warmer ocean temperatures, and both of those are impacting the recent significant declines in sea ice we have observed over the last several decades.”

CAPT. BILL RALL, U.S. COAST GUARD

Cut 4 (00:31) - “Our basic characteristic is that we are 4204 foot polar ice breaker, we are 16,000 ton vessel, which is what helps with the ice breaking, the tonnage is a good portion of what allows to get through the ice, what’s unique about our ship is it was also designed to accommodate scientist so we have large amount of lab space mostly on the aft part of the ship, as well a two A-frame to accommodate the science experiments.”
