Giant Iceberg in McMurdo Sound (WMS)
Iceberg B-15A, in Antarcticas McMurdo Sound, is as large as Long Island, NY (3,000 square kilometers or 1,200 square miles) and is the largest fragment of a much larger iceberg that broke away from the Ross Ice Shelf in March 2000. Iceberg B-15A has trapped sea ice in McMurdo Sound, and the ice build-up presents significant problems for Antarctic penguins, which must now swim great distances to reach open waters and food. These images were taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on NASAs Aqua and Terra satellites between 2004-11-09 and 2005-01-17.
