Warm ocean drives most Antarctic ice shelf loss, UC Irvine and others show

Findings are a game changer for future forecasts about thawing continent

Irvine, Calif. – Ocean waters melting the undersides of Antarctic ice shelves, not icebergs calving into the sea, are responsible for most of the continent’s ice loss, a study by UC Irvine and others has found.

The first comprehensive survey of all Antarctic ice shelves discovered that basal melt, or…
