Outlines of distinguishable submerged aquatic vegetation (SAV) signatures in the aerial photography were digitized in a GIS environment, supplemented by visual examination of the photographic prints. ESRI polygon coverage of SAV beds was created in ArcView version 3.2. To provide historic information on the distribution of submerged aquatic vegetation (SAV) in coastal Alabama, primarily in portions of Mobile County during October 1940 and Baldwin County during January 1955. This information contributes to the Mobile Bay National Estuary Program (MBNEP) living resources goal of identifying historic changes in the distribution of SAV in coastal Alabama. The acreage of SAV in the historic photography was compared with the 2002 MBNEP SAV survey to assess distributional differences, and develop a priority list of potential SAV restoration sites for coastal Alabama. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0162477 Preview graphic PNG 0162477 NCEI ACCESSION NUMBER 2016-10-27 publication HABITAT theme NODC DATA TYPES THESAURUS photograph instrument NODC INSTRUMENT TYPES THESAURUS aerial photography biological composition & location GIS product theme NODC OBSERVATION TYPES THESAURUS Dauphin Island Sea Lab dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS Mobile Bay National Estuary Program (MBNEP) project NODC PROJECT NAMES THESAURUS Coastal Waters of Alabama Gulf of Mexico place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication SAV Submerged Aquatic Vegetation coastal habitats theme Provider Keywords airplane instrument Provider Instruments OCEAN > ATLANTIC OCEAN > NORTH ATLANTIC OCEAN > GULF OF AMERICA OCEAN > ATLANTIC OCEAN > NORTH ATLANTIC OCEAN > GULF OF MEXICO place Global Change Master Directory (GCMD) Location Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
