Description
Summary:Global sea-level rise contributed by Antarctic ice-mass loss could soon outpace all other sources. The ice-mass-loss signal of the Antarctic Ice Sheet is dominated by the Amundsen Sea Embayment (ASE) in West Antarctica. Ice shelves in the ASE influence the ice-mass-loss rates of the Antarctic Ice Sheet through their ability to buttress the grounded ice and modulate ice-flow speed. Ice shelves reduce ice flow and retreat by buttressing grounded ice. Previous studies show that sea ice can buttress ice shelves via mechanical bonding and provide protection from ocean swells. Whereas several studies have examined the trends in West Antarctic sea ice and dynamics of ice shelves in the ASE separately, the interaction between ice shelves and sea ice in the ASE is poorly understood. This study investigated the relationship between sea-ice-area (SIA) anomalies and ice-shelf velocities of three large ASE ice shelves, of Thwaites Eastern Ice Shelf (TEIS), Pine Island Glacier Ice Shelf (PIGIS) and Crosson Ice Shelf ...
