Sub-glacier terrain affects sea levels

Fresh research into glaciers could help scientists better predict the impact of changing climates on global sea levels. Scientists have shown for the first time that the terrain beneath glaciers influences how much glacier melt contributes to fluctuations in sea levels. Researchers say the study will improve their understanding of how ice sheet movements have affected sea levels in the past. New research will also enable more accurate projections of future change. Ice age evidence. Scientists from the University studied the Slessor glacier in the Weddell Sea bay in Antarctica. They found surprising evidence that ice thickness in the region has not changed markedly since the last ice age.
