The webinar provided an overview of the Work Package 3 (WP3). WP3 focuses on providing updated values and uncertainties for freshwater fluxes from the Antarctic Ice Sheet to the ocean over the satellite observational period to the present day, including surface melt and runoff, ice flow, basal melting and calving. The webinar opened with an overview of the aims and objectives of OCEAN ICE WP3. A series of talks covered ice-sheet mass balance, forcing and dynamics, freshwater release from the ice-sheet surface, and iceberg calving around the continent. The webinar continued with a talk on estimating ice-shelf basal melt rates from in-situ observations and concluded with an update on WISH-OI activities within WP3.
