This grant is for the coordination of and participation in the Seasonal Ice Zone Reconnaissance Surveys SIZRS program of repeated ocean, ice, and atmospheric measurements across the Beaufort-Chukchi sea seasonal sea ice zone SIZ utilizing US Coast Guard Arctic Domain Awareness ADA flights of opportunity. The long-term goal of SIZRS is to track and understand the interplay among the ice, atmosphere, and ocean contributing to the rapid decline in summer ice extent that has occurred in recent years. The SIZ is the region between maximum winter sea ice extent and minimum summer sea ice extent. As such, it contains the full range of positions of the marginal ice zone MIZ where sea ice interacts with open water. In addition to SIZRS coordination, this grant covers our profile measurements of temperature, salinity, velocity and mixing across the SIZ, with the long-term goal of understanding the role of the ocean in controlling the evolution of the SIZ.
