The scene might look like the surface of the moon, but the feature is actually the mottled underside of a melt pond on sea ice in the Arctic Ocean. The ICEPRO instrument was deployed below the melt ponds and bare ice during the ICESCAPE mission to measure the amount of light at various depths.


The ICESCAPE mission, or "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," is NASA's two-year shipborne investigation to study how changing conditions in the Arctic affect the ocean's chemistry and ecosystems. The bulk of the research takes place in the Beaufort and Chukchi seas in summer 2010 and 2011.
