Description:
Abstract:
This is a GIS data layer of polygons representing Submerged Aquatic Vegetation of Barnegat Bay, 1968, originally mapped by the Army Corps of Engineers and State of New Jersey 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. Please note: unlike other submerged aquatic vegetation data layers in this temporal series, submerged aquatic vegetation was not mapped in Little Egg Harbor for this particular year.
Purpose:
The sav68.shp was created as part of the 'Landscape Scale Approaches to Coastal Habitat Conservation - Barnegat Bay' study. This study focuses 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.
Supplemental_Information:
It should be noted that at the time of the original Army Corps of Engineers and State of New Jersey publication (1976), the purpose of their report was to investigate problems associated with "excessive aquatic plant growth" and to determine methods to resolve the perceived problem. Areas of overly abundant sea lettuce, eelgrass, and wigeongrass growth were deemed "infested" and in most cases these species were considered weeds. These aquatic plants were described as "nuisances to navigation, recreation, and public health".

These maps as presented provide a regional picture of SAV distribution at various points in time and are not intended for site level permit applications or litigation purposes. These maps and data, alone, are not sufficient to determine the presence or absence of SAV. Conclusive evidence concerning the presence or absence of SAV requires site inspections, preferably at several points in time during the SAV growing season.

Data are supplied 'as-is' without warranty of any kind. While efforts have been made to ensure that these data are accurate and reliable within the state of the art, Rutgers University cannot assume liability for any damages, or misrepresentations, caused by any inaccuracies in the data. Rutgers University makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty.

Any maps, publications, reports or any other type of document produced as a result of utilizing this data will credit the original map author(s) as listed as well as the Center for Remote Sensing and Spatial Analysis (CRSSA), Rutgers University.

The sav68 coverage was compared to existing Arc/INFO coverages of Barnegat Bay and the New Jersey coastline (coastply2) to ensure spatial accuracy. The original source paper map had no graticule and was not georeferenced.

Horizontal accuracy is based on geo-spatial comparsion to rectified orthophotography and mutiple digital boundary sources.

Process_Step:
Process_Description:
Sav68.shp was created through the digitization of aquatic plant delineations mapped in the 1968 Aquatic Plant Survey Map. Forty-three ground control points were established by comparing the source map (1968 Aquatic Plant Survey) to a reference image (NOAA nautical chart image 123161.img) using Erdas Imagine. The SAV68 coverage was then compared to existing Arc/Info coverages of Barnegat Bay and the New Jersey coastline (coastply2) to ensure spatial accuracy. The original paper source map had no graticule and was not geo-referenced.
