Sea ice across the Arctic Ocean is shrinking to below-average levels this summer. NASA’s Operation IceBridge, an airborne survey of polar ice, just completed its first flights studying the aquamarine pools of melt water on the ice surface that may be accelerating the overall sea ice retreat.
This large pool of melt water over sea ice was seen from an Operation IceBridge flight over the Beaufort Sea on July 14, 2016. During this summer campaign, IceBridge will map the extent, frequency and depth of melt ponds like these to help scientists forecast the Arctic sea ice yearly minimum extent in September.
