Franz Josef Land, Russia

Franz Josef Land is an archipelago in the far north of Russia. It consists of 191 islands covering an area of about 200 by 325 km, and has no native inhabitants. Discovered in the mid-19th century, the archipelago has a population of about 1200, and is part of the Russian Arctic National Park. The ASTER images show the islands of Salisbury, Luigi, Champ, Ziegler; the images were acquired August 16 and 19, 2011, cover an area of 68 x 90 km, and are located at 81 degrees north latitude, 56.6 degrees east longitude.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
