researchers found that the Smith
Glacier retreated by about 21 miles during the period from 1996 to 2011. The scientists concluded that the size of the retreat was partly a result of both the unique topography underneath the ice that allowed more ocean water to sneak in between the ice and the land below.

In 2001, Dr. Andrew
Shepherd, a research fellow at the Center for Polar Observation and Modeling at University College London, said that Smith Glacier was losing mass quickly and contributing to the slow rise of the oceans. In 2011, Hamish Pritchard, a scientist with the British Antarctic Survey in

which relied on airborne radar measurements, found that melting of the ice shelves’ grounding zones between the years 2000 and 2009 removed between 984 and about 1,607 feet of solid ice beneath the Smith
Glacier. The Smith Glacier lost more ice than any other glacier studied for the report. The

Using a second instrument on the satellite, one that measures altitude, Dr. Andrew
Shepherd, a research fellow at the Center for Polar Observation and Modeling at University College London, came to similar conclusions. A smaller, neighboring glacier, the Smith glacier, is losing mass even more

The study, which relied on airborne radar measurements, found that melting of the ice shelves' grounding zones (which is where the ice meets the ocean and becomes floating ice) removed between 984 to about 1,607 feet of solid ice beneath the Smith
Glacier alone between the years 2000 and

Yet according to
Pritchard, glaciers along West Antarctica's midpoint are thinning at an accelerated pace: the Pine Island glacier is thinning by up to 18 feet per year, the neighboring Smith glacier by 27 feet per year, and the Thwaites glacier by 12 feet per
