High Resolution Imagery of Buck Island Coral Reef Systems Prior to and During Suspected Bleaching Events

Chris Elvidge National Oceanic and Atmospheric Administration (NOAA) / National Geophysical Data Center (NGDC) 325 Broadway Boulder CO 80305 200908 High Resolution Imagery of Buck Island Coral Reef Systems Prior to and During Suspected Bleaching Events Remote-sensing image http://www.ngdc.noaa.gov/dmsp/coral/index.html This dataset is a collection of imagery of Buck Island coral reef systems. They are pairs of imagery where one image was acquired during a suspected bleaching event. The second is a control image taken at some point prior to the event. The images are co-located and radiometrically calibrated for comparison. The difference images are analyzed for evidence of bleaching. Additional information on methodology can be found here: http://www.ngdc.noaa.gov/dmsp/coral/methodology.html These data were analyzed with the purpose of developing a semi-automated quantitative measure of coral reef bleaching. 20011210 20050918 Ground Condition Complete None Buck Island in the Virgin Islands in the Caribbean. -64.65 -64.6 17.816 17.75 CoRIS Theme Thesaurus EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Mapping > Base map > Satellite Imagery ISO 19115 Topic Category imageryBaseMapsEarthCover 010 CoRIS Discovery Thesaurus Visual Images > Corals CoRIS Place Thesaurus OCEAN BASIN > Atlantic Ocean > Caribbean Sea > Virgin Islands > Buck Island > Buck Island (17N064W0006) COUNTRY/TERRITORY > United States of America > U.
