The picture shows a ridge in Greenland that shares a pair of glacier valleys. The deep blue of a fjord and the Arctic sky interrupt the snow-capped mountains.
The last Operation IceBridge flight took 8.5 hours and allowed scientists to collect data on several glaciers and other points of interest.
The IceBridge mission is the largest airborne polar survey to date. Flights over Greenland will take until May. In October and November scientists will study the Antarctic.
"It provides unprecedented three-dimensional views of Arctic and Antarctic ice sheets, ice shelves and sea ice," NASA wrote in a caption accompanying the new image. "These flights provide an annual overview of the behavior of the rapidly changing features of Greenland and Antarctic ice."
Previous research has shown that temperatures in the polar regions of the planet are accelerating and glaciers are shrinking and sea ice is shrinking.
Climatologists and glaciologists are working to better understand these trends so they can more accurately predict how climate change will raise sea levels and a range of weather and ocean systems.
