One of the most consequential places on earth is also one of its least accessible: Antarctica’s icy underbelly. The grounding line is where the terrestrial ice sheet reaches the sea and begins floating, becoming the ice shelf. As global temperatures rise, seawater is eating away at that belly, forcing the grounding line to retreat and speeding the decline of Antarctica’s glaciers. Two new papers, though, are shining light on this mysterious realm. Alexander Robel, assistant professor in the School of Earth and Atmospheric Sciences who leads Georgia Tech's Ice and Climate Group, did not participate in the studies but is quoted in the article.
