NASA IceBridge3245 viewsThe Operation IceBridge mission, initiated in 2009, collects airborne remote sensing measurements to bridge the gap between NASA's Ice, Cloud and Land Elevation Satellite (ICESat-I) mission and the upcoming ICESat-II mission. This photo was taken over the Patagonian ice fields, on November 23, 2009.

Arctic Sea Ice News & Analysis3599 viewsThis image compares the average sea ice extent for September 2007 to September 2005; the magenta line indicates the long-term median from 1979 to 2000. September 2007 sea ice extent was 4.28 million square kilometers (1.65 million square miles), compared to 5.57 million square kilometers (2.14 million square miles) in September 2005. This image is from the NSIDC Sea Ice Index.

480 viewsAreas that contain much permafrost can look barren. But plants and animals prosper here in the summer days, when the top layer of frozen ground thaws. The caribou in this photograph, in the Noatak National Preserve, Alaska, are migrating in the early fall.

1664 viewsThis Landsat image of Crane Glacier on the Antarctic Peninsula is overlain with ICESat and Airborne Topopgraphic Mapper (ATM) tracks. ATM is a lidar sensor that is now part of the IceBridge mission. Over time, ICESat and ATM measurements, together with visible imagery, can detect thinning of the ice and accelerated flow of ice into the ocean. Large glaciers such as Crane have the potential to contribute significantly to sea level rise.
