Historical Submerged Aquatic Vegetation (SAV) Distributions from Coastal Alabama, Gulf of Mexico from 1940-01-01 to 1966-10-21 (NCEI Accession 0162477)

browse graphicPreview graphic
Historic black and white aerial photographs of coastal Alabama (Mobile Bay and adjacent waters) from 1940, 1955, and 1966 were digitized and georeferenced using Blue Marble Geographic Transformer version 5.1. 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.

Supplemental Information
Submission Package ID: YLDJ73
Purpose 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.
