This is a GIS data layer of polygons representing Submerged Aquatic Vegetation of Barnegat Bay - Little Egg Harbor, 1979, originally mapped by Robert T. Macomber and Dick Allen and digitized by the Grant F. Walton Center for Remote Sensing and Spatial Analysis (CRSSA), Rutgers University. Included are the submerged aquatic vegetation types mapped throughout the study area and their respective area and perimeter for each polygon.
The sav79.shp was created as part of the 'Landscape Scale Approaches to Coastal Habitat Conservation - Barnegat Bay' study. This study focused on the loss of submerged aquatic vegetation (SAV) that is occuring in Barnegat Bay as a result of human modification and decreasing water quality in the bay and watershed across time. CRSSA has compiled SAV studies conducted in the 1960's, 1970's, 1980's, 1990's to facilitate habitat loss assessment in Barnegat Bay. As of this writing, CRSSA continues to map and monitor submerged aquatic vegetation as part of its on-going Coastal Studies Program.
