Comparison of variations in sea-ice formation in the Weddell Sea with seasonal bottom-water outflow data

Seasonal and interannual variability of Antarctic sea-ice formation is observed using ERS-1 satellite microwave radar in the Weddell Sea. Time-series from six Antarctic regions with recurring ice-shelf polynya systems indicate relationships between the timing of seasonal peaks in measured bottom water outflow and ice formation rates. Results provide evidence about the critical periods of high surface heat fluxes and clues to primary brine production locations.
