WebOct 25, 2024 · Surface melt is an important driver of ice shelf disintegration and its consequent mass loss over the Antarctic Ice Sheet. Monitoring surface melt using satellite remote sensing can enhance our understanding of ice shelf stability. However, the sensors do not measure the actual physical process of surface melt, but rather observe the … WebAntarctica’s northern George VI Ice Shelf experienced record melting during the 2024-2024 summer season compared to 31 previous summers of dramatically lower melt, a CU Boulder-led study found. The extreme melt coincided with record-setting stretches when local surface air temperatures were at or above the freezing point.
