Description:

Abstract:

Water quality in the Barnegat Bay estuary along the New Jersey coast is the focus of a multidisciplinary research project begun in 2011 by the U.S. Geological Survey (USGS) in cooperation with the New Jersey Department of Environmental Protection. This narrow estuary is the drainage for the Barnegat Bay watershed and flushed by just three inlets connecting it to the Atlantic Ocean, is experiencing degraded water quality, algal blooms, loss of seagrass, and increases in oxygen-depletion events. The scale of the estuary and the scope of the problems within it required a regional approach to understand and model water circulation within the bay and adjacent ocean. A continuous elevation surface (terrain model) integrating all available elevation data in the area was produced for the water circulation modeling efforts.

Purpose:

The purpose of this polygon shapefile is to delineate the general boundaries and spatial extent of the edited, input data used to create the terrain model (bbtg10m.tif)

Data_Quality_Information:

Logical_Consistency_Report:

Polygon boundaries were created using the spatial extent of the input files used to create the terrain model. The boundaries for the source "NED" and "USGS EAARL" attributes were created by converting the raster data directly to a polygon. The boundaries of the remaining datasets were created by digitizing a boundary polygon around the extent of each of the datasets such that adjacent polygons do not overlap.

Completeness_Report:

The individual polygons only delineate the extent of bathymetric data used to compile the bathymetric terrain model and may not include all the data collected during the individual survey.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

This polygon shapefile was generated by a combination of digitizing around survey data, and converting rasters to polygons. Each feature in the shapefile encompasses the complete extent of each input dataset.
