Abstract:

The Submerged Aquatic Vegetation in Barnegat Bay - 1985-87 shapefile (sav85_87.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. The areas in this coverage were digitized in an effort to document and assess long-term

trends of habitat loss in the Barnegat Bay region.The data for this coverage was extracted from a

report submitted by the Marine Fisheries Administration (Division of Fish, Game and Wildlife,

NJDEP) in January 1992. That report (The Influence of Water Depth and Bottom Sediment on the

Occurence of Eelgrass) was based on a survey conducted by the Bureau of Shellfisheries.

Inventories of eelgrass distribution, water depth,and bottom sediments were collected for Barnegat,

Little Egg Harbor, and Manahawkin Bays from 1985 to 1987.

The SAV8587 Arc/INFO coverage is a mosaic, created through the digitization of eelgrass delineations

mapped in the Marine Fisheries' report. The digitized eelgrass areas were subsequently compared

with the NJDEP "coast" coverage (editted to coastply2) to ensure spatial accuracy.
 

Purpose:

The sav85_87.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

earlier and subsequent SAV studies conducted in the 1960's, 1970's, and 1990's and created

shapefiles to facilitate habitat loss assessment in Barnegat Bay.

These maps, as presented on this web site, 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.

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 sav85_87 shapefile was compared to existing Arc/INFO coverages of Barnegat Bay and

the New Jersey coastline (coastply2) to ensure spatial accuracy. The original source

paper maps graticule was also utilized to geo-reference sav85_87.shp during digitization.

Process_Step:

Process_Description:

The graticules of Marine Fisheries' report maps were projected from lat/long coordinates
(degrees, minutes, seconds) into UTM Datum NAD27 coordinates in Arc/Info. "Eelgrass" and
"No Data" areas were then digitized and saved in an Arc/Info coverage (SAV8027) in  UTM
Datum NAD27 coordinates. The initial coverage (SAV8027) was then projected into UTM
Datum NAD83 coordinates (saved as Arc/Info coverage SAV80) and subsequently compared
to existing Arc/INFO coverages of Barnegat Bay and the New Jersey coastline (coastply2) to
ensure spatial accuracy. SAV80 was then converted to sav0.shp in ArcView. In this shapefile
the submerged aquatic vegetation (SAV) areas are synonomous with the eelgrass areas of the
Marine Fisheries' report. The "no data - assumed eelgrass" areas are the result of the Bureau
of Shellfisheries inability to enter shallow waters (<3feet).
