First scientist to measure West Antarctic Ice Sheet dies
Charles Bentley, who in the 1950s led an expedition that measured the West Antarctic Ice Sheet for the first time, has passed away aged 87. Spending 25 consecutive months on the ice, the American glaciologist discovered the 3,000-metre-thick ice sheet was equally submerged under sea as it was above. Bentley made about 15 trips over seven decades to the Antarctic.
