Sustained Greenland Ice Sheet-Ocean Observing System

The Case for a Sustained Greenland Ice Sheet-Ocean Observing System (GrIOOS)

Rapid mass loss from the Greenland Ice Sheet is affecting sea level and, through increased freshwater discharge, ocean circulation, sea-ice, biogeochemistry, and marine ecosystems around Greenland. Key to interpreting ongoing and projecting future ice loss, and its impact on the ocean, is understanding exchanges of heat, freshwater, and nutrients that occur at Greenland's marine margins.
