High-Resolution Imagery of Sea Ice Data Available from USGS

In the 1990s, the Medea program began a collection of classified reconnaissance imagery of sea ice and other sites of interest to environmental scientists. Acquisition of these images has continued, with some changes and interruptions, to this day. Thousands of images are archived by the USGS Global Fiducial Library (GFL) and are now being made publicly available. Sea ice images are among the first of the classified, 1-meter resolution visible band images to be publicly released by the GFL.
