Summary

English: Mar Menor, in southeast Spain, is Europe's largest coastal saltwater lagoon. For the past 40 years, Mar Menor has faced severe contamination from agricultural runoff, leading to large algal blooms, and ecological degradation. Now, major restoration and prevention programs are in place to restore the lagoon, and try to reverse the damage. The image was acquired August 24, 2023, covers an area of 22.6 by 27.4 km, and is located at 37.7 degrees north, 0.8 degrees west. With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of about 50 to 300 feet (15 to 90 meters), 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. https://photojournal.jpl.nasa.gov/catalog/PIA26009 |
