A major goal of this proposal will be to improve the net surface mass balance estimate of Antarctica by incorporating the mass loss due to wind-drifted sublimation over wind-scour zones.
In recent years, scientists have discovered hundreds of lakes lying hidden deep beneath the Antarctic ice sheet. Now a team of researchers has found the remains of at least one sub-ice lake that existed when the ice was far more extensive, in sediments on the Antarctic continental shelf. The discovery is significant because it is thought that such lakes may have accelerated the retreat of glaciers in the past, and could do so again. Their study appears this week in the journal Nature Communications.
