SASSIE Arctic Field Campaign Shipboard Delta-18O Data Fall 2022

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 delta-18O measurements from sea water and ice. Delta-18O is the ratio of stable isotopes oxygen-18 (18O) and oxygen-16. Water samples were collected from either a GoFlo bottle lowered from the side of the ship, or the outflow of the Salinity Snake. Ice samples (dimension ice_obs) were collected during two ice stations where augur tailings were collected and melted. Data are available in netCDF format.
