Deicing of the Arctic

NASA / Kathryn Hansen.

NASA / Kathryn Hansen.

During the spring and summer melt, the sea ice atop the Arctic Ocean (shown here in this photo from July 12, 2011) begins to melt; the liquid water collects in depressions on the surface, pressing down on them and making them deeper until they become melt ponds. These freshwater ponds stay separated from the salty sea below and around it until cracks in the ice let the two mix.

Scientists who are part of NASA’s ICESCAPE mission (Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment) are studying these melt ponds and the surrounding water and ice to see how changes in the Arctic impact the ocean’s chemical and biological makeup.

That is a really cool landscape, don”t you agree?

    Hi Linda! How very odd! Fresh water floating within salty oceans? You wait someone will figure out a way to “farm” that water and really set off an ecological change…
