Oceanographer discovers how warming waters thousands of miles away increase melting across West Antarctic ice shelf

By Ananya Chandhok Medill Reports, Feb. 20, 2024 How ocean currents circulate heat over thousands of miles is critical for University of Washington oceanographer Channing Prend to understand ice melt in Antarctica.  Prend’s research on the West Antarctic ice sheet revealed that heat from water thousands of miles to the north can lead to ice …

SCIENTISTS SEARCH ANCIENT ICE FOR CLUES AS GREENLAND ICE MELT RAPIDLY INCREASES

The Greenland ice sheet is more than three times the size of Texas, 2 miles deep at its thickest point. And it’s melting.

Not only is it melting, but it’s melting at a rate not seen in 400 years, according to a paper published in Geophysical Research Letters in April. The study involved taking short ice core samples and examining the surface layers of snow to find out how much melting had occurred.
