|a We use satellite observations to show that, between
1992 and 2011, the Pine Island Glacier hinge line retreated
at a rate of 0.95, plus or minus,0.09 km yr -1 despite a progressive
steepening and shoaling of the glacier surface and bedrock
slopes, respectively, which ought to impede retreat. The
retreat has remained constant because the glacier terminus
has thinned at an accelerating rate of 0.53, plus or minus,0.15 m yr -2,
with comparable changes upstream. This acceleration is
consistent with an intensification of ocean-driven melting in
the cavity beneath the floating section of the glacier. The
pattern of hinge-line retreat meanders and is concentrated in
isolated regions until ice becomes locally buoyant. Because
the glacier-ocean system does not appear to have reached a
position of relative stability, the lower limit of sea level
projections may be too conservative. |
