Preferred term

SASSIE  

Definition

  • Sea ice extent in the Arctic Ocean has declined dramatically over the past decades. Autumn ice advance is slower and occurs later, while summer ice retreat is faster and occurs earlier. The result is a lengthening open-water period each year, leading to changes in air-sea heat and momentum fluxes, the freshwater cycle, surface albedo feedbacks, primary production, and regional and global climate as well as human and ecological health. Our experiment examines how summer ice melt evolves into and is inexorably linked with autumn sea ice advance. A major SASSIE milestone was completed in September 2022: a monthlong scientific cruise in the Bering Sea aboard the R/V Woldstad. (en)
