View Image Comparison View Both Images The Petermann Glacier slides toward the sea along the northwestern coast of Greenland, terminating in a giant floating ice tongue. Like other glaciers that end in the ocean, Petermann periodically calves icebergs. A massive iceberg, or ice island, broke off the Petermann Glacier in 2010. Nearly two years later, another chunk of ice has broken free. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite observed the new iceberg calving on July 16, 2012. Because Aqua is a polar-orbiting satellite, it makes multiple passes over the Polar Regions each day. At 10:25 Coordinated Universal Time (UTC), the iceberg remained close to the glacier. By 12:00 UTC, the iceberg had moved northward down the fjord. Konrad Steffen, director of the Swiss Federal Institute for Forest, Snow, and Landscape Research, estimated tha...
