Warm Water Is Rapidly Eroding Antarctica’s Ross Ice Shelf
The underside of the world’s largest ice shelf is melting—by meters per year in some places—because of the seasonal inflow of water heated by the Sun, observations of the White Continent reveal.

Very Warm Water Observed Along West Antarctic Ice Shelf
Two years of mooring observations at the edge of the continental shelf show that wind stress and upwelling control the inflow of some of the warmest water observed at an ice shelf front in Antarctica.
