Seaglider observations were collected in and around the Belgica Trough in the Bellingshausen Sea, Antarctica, and over the continental slope to the immediate north. The campaign aimed at resolving the narrow boundary currents of the trough's circulation, as well as extending observational coverage in an under-studied region (i.e. the Bellingshausen Sea). The Seaglider was prepared and piloted by the University of East Anglia (COMPASS), deployed 01 Feb 2020 and recovered 20 Mar 2020 from the RV Nathaniel B Palmer by the California Institute of Technology (TABASCO), who also assisted with piloting. The observations include temperature, conductivity, density, salinity, chlorophyll and backscatter data.
