The Canadian Space Agency CSA in partnership with MacDonald, Dettwiler and Associates Ltd. MDA, and the Canadian Cryospheric Information Network (CCIN) at UWaterloo, have made public a mosaic of over 3,150 images collected by the RADARSAT-2 satellite. The images were captured with the Synthetic Aperture Radar aboard RADARSAT-2 in 2008 covering all of Antarctica.
The mosaic is now freely accessible to the public. “The mosaic provides an update on the ever-changing ice cover in this area that will be of great interest to climatologists, geologists, biologists and oceanographers,” said Professor Ellsworth LeDrew, director of the CCIN and a professor in the Faculty of... read more

NASA's Landsat 8 satellite defined the coldest place on Earth - a high ridge in Antarctica on the East Antarctic Plateau where temperatures in several hollows can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees ) on a clear winter night.
Scientists from NASA evaluated 21 years’ worth of... read more

The DLR-operated TerraSAR-X Earth observation satellite has documented the gradual propagation of the first crack in the Pine Island Glacier (PIG) over a period of several months. PIG is the longest and fastest flowing glacier in the western Antarctic, flowing from the Hudson Mountains into the Amundsen Sea. The satellite data confirmed the crack's expansion to full width and the spawning of a new iceberg of the size of Hamburg, as a result of... read more

Satellites show that the recent ozone hole over Antarctica was the smallest seen in the past decade. Long-term observations also reveal that Earth’s ozone has been strengthening following international agreements to protect this vital layer of the atmosphere.
According to the ozone sensor on Europe’s MetOp weather satellite, the hole over Antarctica in 2012 was the smallest in the last 10 years. The instrument continues the long-term monitoring of atmospheric ozone started by its predecessors on the ERS-2 and Envisat satellites.
Since the beginning of the 1980s, an ozone hole has developed over... read more
