The Salinity and Stratification at the Sea Ice Edge (SASSIE) project is a NASA experiment that aims to understand how salinity anomalies in the upper ocean generated by melting sea ice affect sea surface temperature (SST), stratification, and subsequent sea-ice growth. SASSIE involved a field campaign that sampled the transition from summer melt to autumn ice advance in the Beaufort Sea during August-October 2022, making intensive in situ and remote sensing observations within ~200km of the sea ice edge. This dataset contains salinity and temperature measurements collected by a shipboard salinity snake. The salinity snake system consisted of a ship-mounted boom with a length of 10m to provide sampling of undisturbed water at a depth of 1-2cm. Salinity data are delayed by 40s, which is the average residence time in the hose, pump, and shipboard system before being analyzed. Data are available in netCDF format.
