The NASA IceBridge Sea Ice Freeboard, Snow Depth, and Thickness Quick Look evaluation product is now available from NSIDC. To access data, see the IceBridge Sea Ice Freeboard, Snow Depth, and Thickness Quick Look Web page.
IceBridge evaluation products are derived from published IceBridge data sets, and are made available to the public for review and exploration of their usefulness and appropriateness for further study and research. For more on evaluation products, see the IceBridge collection page.
The Antarctic Glaciological Data Center (AGDC) at NSIDC has published new data sets. AGDC archives and distribtues data from National Science Foundation Office of Polar Programs-funded researchers.
The Antarctic Glaciological Data Center (AGDC) at NSIDC has published the ASTER GDEM 100-m Digital Elevation Model of the Antarctic Peninsula. The data set provides a 100-meter resolution surface topography Digital Elevation Model (DEM) of the Antarctic Peninsula. The DEM is based on Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) Version 1 data.

The Global Lake and River Ice Phenology database has seasonal freeze-up and breakup dates as well as other descriptive ice information for 865 lakes and rivers in twelve Northern Hemisphere countries. Sixty-six of these bodies of water have records longer than 50 years. In cooperation with the Lake Ice Analysis Group (LIAG) at the University of Wisconsin, Madison, NOAA@NSIDC has updated and added to the database, increasing the number of lakes and rivers it holds by over 13 percent.
A calendar correction was made to the Lake Suwa, Japan data.
