SASSIE Arctic Field Campaign Shipboard Castaway CTD Data Fall 2022 Version 1

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 ~200 km of the sea ice edge. This dataset contains profiles of upper ocean temperature, salinity, and density taken with a Shipboard CastAway Conductivity-Temperature-Depth instrument (CastAway-CTD). A total of 254 profiles were taken over the sampling period at various locations, typically every 30 minutes while the ship was underway, with a mean depth of 45m. Data are available in NetCDF format.
