TY  - JOUR
AB  - A  large  volume  of  the  East  Antarctic  Ice  Sheet  drains  through  the  Totten Glacier (TG) and is thought to be a potential source of substantial global sea level rise over the coming centuries.   We show the flow and surface height of floating part of TG, which buttresses the grounded component, have varied  substantially  over  two  decades  (1989–2011),  with  variations  in  surface height and basal melt rates highly anti-correlated (r=0.70, p<0.05). Coupled glacier/ice-shelf simulations confirm ice flow and thickness respond to both basal melting of the ice shelf and grounding on bed obstacles.  We conclude the observed variability of TG is primarily ocean-driven and enhanced ice-sheet dynamism, leading to upstream grounded ice loss, will occur from the region with ocean warming.
