Clew Bay is in County Mayo, Republic of Ireland. It contains Ireland's best example of sunken glacial drumlins. Clew Bay is associated with Grace O'Malley, the Pirate Queen during Elizabethan times; and Dorinish, a private island purchased by John Lennon. The drumlins are low hills formed from glacial sediment deposited at the end of the last Ice Age. The image was acquired May 31, 2016, covers an area of 22.5 by 26.2 km, and is located at 53.9 degrees north, 9.6 degrees west.
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
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.
