Description:

Abstract:

The Submerged Aquatic Vegetation in Barnegat Bay - 1996-1999 shapefile (sav96_99.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. The sav96_99.shp is the result of the appending the GPS point data collected in the
'Assessment of the health and distribution of  Submerged Aquatic Vegetation from Little Egg
Harbor, New Jersey' study conducted by Dr. Paul Bologna in the summer of 1999, to the existing
shapefile 'ocecosav98'. The ocecosav98.shp is the product of the CRSSA in-house digitization of
Paul "Pete" McLain's 'Barnegat Bay Eelgrass Investigation', completed in the summer of 1998.

Purpose:

The sav99.shp was initially 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 also compiled

earlier SAV studies conducted in the 1960's, 1970's, and 1980's and created shapefiles to

facilitate habitat loss assessment in Barnegat Bay. The sav96_99.shp was also included in the

'Boater's Guide to Barnegat Bay and Little Egg Harbor', completed at CRSSA in 200002.

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.

Process_Step:

Process_Description:

The submerged aquatic vegetation (SAV) areas in the contributing ocecosav98.shp were digitized

from paper maps on an Altek digiting table using standard digitizing methods. The GPS data collected

by Dr. Paul Bologna (Institute of Marine and Coastal Sciences, Rutgers University) was differentially

corrected at CRSSA utilizing Trimble Pathfinder Office software,and subsequently exported for inclusion

in a GIS. The additional areas delineated by the GPS data set were appended to the existing

ocecosav98.shp to create sav96_99.shp. Note that the appendage of Dr. Bologna's SAV area delineations

convey a "best case scenario" for the presence of SAV. Therefore, any SAV areas from the existing

ocecosav98.shp not detected in Dr. Bologna's study were left unaltered.
