Abstract:
These data represent trackline navigation data seismic-reflection systems utilized during U.S. Geological Survey geophysical research cruises.
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).

Logical_Consistency_Report:
These navigation data have been stripped from the header of seismic SEG-Y data. They have been quality checked by comparing these data to navigation data acquired during cruise operations.

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). Slant-range distance is recorded between the sidescan-sonar tow vehicle and a sidemount rigged with an acoustic transponder during acquisition of CHIRP sub-bottom data. Offset between thesidemount and GPS antennae is measured. Basic trigonomic calculations use the slant-range offset to calculate a 'fish'(tow-vehicle) navigation. An assumption in these calculations is that the tow-vehicle is traveling directly behind the vessel; movement to port or starboard is not accounted for within 'fish' navigation. Thus, the horizontal accuarcy of the CHIRP tow-vehicle is +/- 15 meters. The horizontal positioning for boomer, sparker, and water gun seismic systems did not account for source and receiver offsets and offset the GPS antennae and the source and streamer. It is estimated that these offsets could lead to inaccuracies of about 30 m.

Process_Step:
Process_Description:
The seismic shot navigation is received by the differential GPS system (DGPS), sent directly to the seismic acquisition system, and recorded in the SEG-Y header of each file. The navigation is later extracted from the header, and formatted into a comma-delimited ArcView Ungenerate text format. The file is then imported into ArcView, and a vector line shapefile is generated. The line numbers for each trackline are stored in an ASCII file listing unique track ID and line number. This file is imported into ArcView 3.2 as a table. The file is then joined to the line shapefile by the unique track ID. The table for the trackline file is the editted, a new field created, the line number information written to this new field, the join removed, and the file saved. This permantely saves the line number with the corresponding trackline.
