The focus of this project is to work collaboratively with Dr. Donald Perovich (CRREL) in support of a NASA sponsored program, ICESCAPES. Bonnie Light will support this project by helping to characterize the morphological and optical properties of the sea ice cover through field measurements, radiative transfer modeling, and synthesis.

Some of the greatest observed changes to the rapidly decreasing Arctic ice cover are occurring in the Chukchi and Beaufort Seas, where increased summer ice retreat has created a substantially increased seasonal ice zone. Increased absorption of solar radiation in newly formed areas of open water and the ice albedo feedback have contributed to this decline in the ice cover (Perovich et al., 2007, 2008, 2011). Furthermore, changes in ice type, thickness, ice age, and the timing of melt onset and freezeup may be accelerating this ice albedo feedback. Recent studies have demonstrated substantial increases in solar heat input to…
