Abstract:
This DVD-ROM contains digital high resolution sidescan-sonar data collected during USGS cruise SEAX 96004 aboard the R/V Seaward Explorer. The coverage lies along New York Bight. This DVD-ROM (Digital Versatile Disc-Read Only Memory) has been produced in accordance with the UDF DVD- ROM Standard and is therefore capable of being read on any computing platform that has appropriate DVD-ROM driver software installed. Access to the data and information contained on this DVD-ROM was developed using the HyperText Markup Language (HTML) utilized by the World Wide Web (WWW) project. Development of the DVD-ROM documentation and user interface in HTML allows a user to access the information by using a variety of WWW information browsers (i.e. NCSA Mosaic, Netscape) to facilitate browsing and locating information and data. To access the information contained on this disc with a WWW client browser, open the file 'index.htm' at the top level directory of this DVD-ROM with your selected browser. The HTML documentation is written utilizing some HTML 4.0 enhancements. The disc should be viewable by all WWW browsers but may not properly format on some older WWW browsers. Also, some links to USGS collaborators are available on this DVD-ROM. These links are only accessible if access to the Internet is available during browsing of the DVD-ROM. Software is available on this DVD-ROM for viewing and processing the individual swaths using computer systems running the UNIX operating system.
Purpose:
Beginning in 1995, the USGS, in cooperation with the US 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 seafloor 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 renourishment 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 collected in 1996, USGS cruise SEAX 96004, augments data collected in 1995 with sidescan sonar and seismic reflection data collected within the New York Bight Apex region. This report is an archive of the sidescan-sonar data and DGPS navigation data collected in 1996.

Process_Description:
The metadata was updated to fix format and errors in order to be made available from the Coastal and Marine Hazards and Resources Program (CMHRP) metadata web-accessible folder (WAF). The following edits were made: added series information, added online link, changed publication place to Reston, VA, added the suggested citation, added supplemental information with link to field activity, added USGS Thesaurus with appropriate keywords, added the ISO 19115 Topic Category thesaurus and appropriate keywords, added keywords section with USGS persistent identifier as theme keyword, added the DOI link in the distribution section. Additional minor edits were made to eliminate errors. The metadata date (20010214), but not the contact (except email and contact instructions) was updated. The metadata available from a harvester may supersede metadata available from the publication. Compare the metadata dates to determine which metadata file is most recent.

Overview_Description:
Entity_and_Attribute_Overview:
The data were collected using a Datasonics SIS-1000 sidescan-sonar towfish. The system emits a CHIRP (swept FM) signal from 100-113 kHz. The return signal is correlated with the calibrated outgoing signal and matched filtered to extract the signal amplitude for each data sample. The signal is digitized at the towfish and sent up the cable where it is collected and merged with bathymetry, navigation and towfish telemetry (pitch, roll) using Triton Elics International ISIS system. The collected sidescan-sonar data are stored as 16 bit values representing a 0-10 volt range.
