Description:
Abstract:
These data represent single beam echo sounder (trackline) bathymetry collected in May 1995, May 1996, September 1996, May 1997, and October 1998 during five USGS cruises within the New York Bight region. Trackline spacing during these cruises was 300 meters. These data have been corrected for tidal fluctuations and distance of the transducer below the water line. All values are stored in meters. These data are referenced to Mean Lower Low Water.
Purpose:
Beginning in 1995, the USGS, in cooperation with the U.S Army Corps of Engineers (USACE), New York District, began a program to generate reconnaissance maps of the sea floor offshore of the New York-New Jersey metropolitan area, one of the most populated coastal regions of the United States. The goal of this mapping program is to provide a regional synthesis of the sea-floor environment, including a description of sedimentary environments, sediment texture, seafloor morphology, and geologic history to aid in understanding the impacts of anthropogenic activities, such as ocean dumping. This mapping effort differs from previous studies of this area by obtaining digital, sidescan-sonar images that cover 100 percent of the sea floor. This investigation was motivated by the need to develop an environmentally acceptable solution for the disposal of dredged material from the New York- New Jersey Port, by the need to identify potential sources of sand for nourishment of the southern shore of Long island, and by the opportunity to develop a better understanding of the transport and long-term fate of contaminants by investigations of the present distribution of materials discharged into the New York Bight over the last 100+ years (Schwab and others, 1997).

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
These data are internally consistent and have been compared to multibeam and single-beam bathymetric surveys to check for accuracy. Any differences between this bathymetric data set and others were determined to be within acceptable error given the inherent differences in the various bathymetric data sets (i.e. acquisition system, mode of navigation, density of point, and or swath bathymetry).
Logical_Consistency_Report:
These data are were checked for consistency by plotting the point data with the contoured surface and eliminating suprious and anomolous soundings.
Completeness_Report: Complete
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
DGPS is assumed to be accurate within 1-2 meters. Standard GPS is assumed accurate within 5-10 meters. 99% of the positional data is DGPS. Unless noted, all GPS/DGPS data is referenced to WGS84 (NAD83). The configuration of the fathometer is as follows: The fathometer is mounted on either the port or starboard side of the vessel. Offset between the sidemount and GPS antennae is measured. No measurements were taken of ship's pitch, yaw, heave, or change in draft due to water and fuel usage. Motion of the fathometer is not measured. Horizontal accuarcy of the fathometer is assumed to be within +/- 3 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
A one meter offset was measured from the water line to the tranducer. This offset was added to the bathymetric measurements. Tidal fluctuations have also been accounted for within these data. No motion sensor monitors the movement of the fathometer or vessel (pitch, heave, yaw). As such, the working vertical accuracy of these data is +/- 0.5 - 1 meter. These data are referenced to Mean Lower Low Water.

Process_Step:
Process_Description:
Bathymetric data were extracted from the survey navigation and stored as an ASCII file, listing longitude, latitude, and depth in meters. These data were then reformatted and loaded into MATLAB (MathWorks, Inc.). The trackline spacing during data acquisition was 300 meters.

Process_Step:
Process_Description:
Within MATLAB (MathWorks, Inc), a median filter with a 15 pixel boxcar size was applied to the bathymetric data to remove spurious spikes and anomolous readings. In order to account for the distance of the transducer below the sea surface, one meter was added to the bathymetric values. These data were then corrected for tidal fluctuations. The ADCIRC circulation model was used to extract tidal coefficients at the locations along the cruise track. A low-pass filter was applied to the Sandy Hook, NJ and Montauk Point, NY tidal stations to determine the wind compenent to the tides within the New York Bight region. A weighted distance interpolation was used between the two tidal stations in order to determine the tidal wind component along the cruise track. Final bathymetric values were determined by subtracting the wind component and tidal offset from the original bathymetric measurement. These values were then exported from Matlab and reformatted to load into EarthVision (Dynamic Graphics, Inc.)

Process_Description:
The tidally corrected bathymetric soundings were loaded into EarthVision (Dynamic Graphics, Inc.). These point data were gridded at a 300 meter grid cell size, yielding a grid size of 214 rows x 488 columns. (The 300 meter grid cell size was chosen based on the trackline spacing during data acquisition (300m)).The point data were further editted to remove anomolous points by contouring the bathymetric grid, and using the contour and grid information to locate anomolous soundings. The grid was exported from EarthVision as an ASCII Raster file and edited to create a file suitable for import to ArcView software. The order of rows were flipped, so that the file begins with the lower row, left column and ends with the upper row right column. An ArcView header that descibes the lower left origin of the grid, the grid cell size, the number of rows and columns, and the null value used (-9999). Contour data were also exported from within EarthVision, and reformatted for import into ArcView software as an ESRI generate file.

Process_Description:
The original bathymetric grid extended beyond the bounds of the 1995 and 1996 study areas; the data covered offshore areas from New York - New Jersey to southern shore of Long Isand. A GRIDCLIP script was used in ArcView 3.2 to clip the original bathymetric grid to the bounds of the 1995 and 1996 surveys.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Completely changed the title based on an author (Jane Denny) supplied title. Added online links to the publication and data page in the Identification section, and a link to download the data in the Distribution section. The metadata describes both the grid and the contours, but the contours are the only dataset available for download in a zip file from the publication. Downloading the grid would require downloading individual files within folders. The projection information is for the raster, but the shapefile is probably in geographic, WGS84. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
