Abstract:

Water quality in the Barnegat Bay-Little Egg Harbor 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 partnership with the New Jersey Department of Environmental Protection. This narrow estuary is the drainage for the Barnegat 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, seaweed, stinging nettles, and brown tide. The scale of the estuary and the scope of the problems within it necessitate a multidisciplinary approach that includes characterizing its physical characteristics (for example, depth, magnitude and direction of tidal currents, distribution of seafloor and subseafloor sediment) and modeling how the physical characteristics interact to affect the estuary's water quality. Scientists from USGS Coastal and Marine Geology Program offices in Woods Hole, Massachusetts, and St. Petersburg, Florida, began mapping the seafloor of the Barnegat Bay-Little Egg Harbor estuary in November 2011 and completed in September 2013. With funding from the New Jersey Department of Environmental Protection and logistical support from the USGS New Jersey Water Science Center, they collected data with a suite of geophysical tools, including swath bathymetric sonar for measuring seafloor depth, a sidescan sonar for collecting acoustic-backscatter data (which provides information about seafloor texture and sediment type), and a subbottom profiler for imaging sediment layers beneath the floor of the estuary. 2011-041-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2011-041-FA 2012-003-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2012-003-FA 2013-014-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2013-014-FA 2013-030-FA: http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2013-030-FA

Purpose:

The purpose of these data are to record and identify the 2,010 kilometers of line files collected by the USGS in Barnegat Bay, New Jersey used to generate the three backscatter mosaics published in this report DS937: BarnBayBS_1m.tif, LittleEggInletBS1m.tif, and BarnBayInletsBS_1m.tif.

Logical_Consistency_Report:

Navigation was checked for consistency and any erroneous points were removed during processing. Duplicate names may exist for the "LineName" attribute; however a further query of the data by the "Survey" attribute will produce unique tracklines for each record in this spatial dataset.

Completeness_Report:

This data set includes only those lines that were used to generate the three backscatter mosaics published in this report.

Horizontal_Positional_Accuracy_Report:

KLEIN 3000 and EDGETECH 4200 Navigation for these data were recorded using a Hemisphere DPGS receiver located on top of the cabin house of the R/V Rafael. Offsets between the antenna and sidescan towfish were measured, recorded, and accounted for in the Klein SonarPro acquisition software (v. 10.0) and SonarWiz (v. 7.02).The DGPS is accurate to within 1-2 meters. SWATHPLUS-H Real Time Kinematic (RTK) navigation was used to determine the horizontal position (x, and y coordinates) of the GPS antenna mounted above the SWATHplus-H transducers with sub-meter accuracy. A RTK-enabled motion reference unit (Coda Octopus F190) was mounted directly above the sonar transducers and continuously measured vertical displacement (heave) and attitude (pitch and roll) of the vessel during data acquisition. Horizontal offsets between navigation and attitude antennas and the SWATHplus-H transducers were applied during acquisition in the configuration files for the SWATHplus-H and Coda Octopus F190 software.

SONAR CONFIGURATION: TOWED SIDESCAN BACKSCATTER During USGS Survey 2011-041-FA a Klein 3000 sidescan sonar operating at a frequency of 132 and 445 kHz was used. During the remaining two surveys (2012-003-FA, 2013-014-FA), backscatter data were collected using an EdgeTech 4200 operating on a frequency of 100 and 400 kHz. The Klein and EdgeTech sonars were towed from the port side of the R/V Rafael approximately 1.5 m astern. SWATHPLUS BACKSCATTER backscatter data were acquired using Systems Engineering and Assessment Ltd (SEA) SWATHplus-H interferometric sonar operating at a frequency of 468 kHz. The sonar transducers were mounted on a rigid pole installed on the bow of the R/V Rafael.

Process_Step:

Process_Description:

Step 1: Towed Sidescan Navigation. Navigation for the Klein 3000 and EdgeTech 4200 sidescan sonars were extracted from the raw files at 30 second intervals and converted to text files for each line using XSonar (v. 2.0) (Danforth 1997). The line files for each Julian day were concatenated together into one comma delimited file (*.csv) with the columns: Lon, Lat, JulianDay, LineName. Navigation was processed during each survey in 2011, 2012, and 2013.

Process_Step:

Process_Description:

Step 2: Convert sidescan navigation points to lines. The navigation file ("JulianDay".csv) for each Julian day was converted to an Esri point shapefile ("JulianDay".shp) using the context menu in ArcCatalog (v. 9.3.1) "Create Feature Class from XY Table". The point shapefile for each Julian day was then converted to a polyline shapefile using "Points to Line v.2" with "VAC Extras" toolbar created by VeeAnn Cross (USGS) During this conversion "LineName" and "JulianDay" attributes were carried over so that the each line in the polyline shapefile (JulianDayTrks.shp) has both the line name and Julian day of collection. Each polyline shapefile was then appended into the master feature class within a file geodatabase (SurveyNameBSTrks). Tracklines were created during each survey in 2011, 2012, and 2013.

Process_Description:

Step 3: Create SWATHplus-H backscatter tracklines for data collected in Barnegat and Little Egg Inlets. The backscatter navigation for lines collected using the SWATHplus-H were converted to a polyline shapefile using the methods described in "BarnBayBathTrks.shp" published in this report (http://pubs.usgs.gov/ds/0937/downloads/shapefile/BarnBayBathTrks.zip) because the SWATHplus-H sonar collects bathymetry and backscatter concurrently for all lines. Using the BarnBayBathTrks.shp as a source, each trackline in the Barnegat and Little Egg Inlets were manually selected in ArcMap (v. 9.3.1) and exported to a separate shapefile using the context menu with in ArcMap (v.9.3.1). The "Grid" attribute for the bathymetry tracklines was deleted after exporting to a shapefile.

Step 4: Merge the towed backscatter tracklines with the SWATHplus tracklines. The feature class containing towed backscatter (Klein3000 and EdgeTech 4200) tracklines for each of the four surveys (SurveyNameBSTrks) was merged with the tracklines (SPInletTrks.shp) from Barnegat and Little Egg Inlets using the SWATHplus sonar to create the final polyline shapefile (BarnBayBathTrks.shp) containing all the line files that were used to produce the three backscatter mosaics in this publication.
