Over the last three decades, the Antarctic Peninsula has undergone immense change. Researchers attribute this to both atmospheric and oceanic warming. One large effect of this is the collapse of the Larsen A Ice Shelf in 1995 followed by the break up of Larsen B seven years later. Researchers have now turned their attention to Larsen C, as its neighbors (the large, floating ice platforms that form where the coastline meets the ocean), have met their demise.

Changes that cause thinner ice shelves make it more likely that they will break up, but they also lead to melting. It’s been known that freshwater from melting ice shelves flows into the oceans, contributing to rising sea levels. But scientists were not entirely sure how the oceans themselves contribute to the phenomenon of melting ice shelves, in part because the thick ice prevented larger vessels from accessing the…
