Abstract:
This CD-ROM contains digital high resolution seismic reflection data collected during the USGS DIAN 97011 cruise. The coverage is the nearshore of Long Island, NY in the vicinity of Fire Island. The seismic-reflection data are stored as SEG-Y standard format that can be read and manipulated by most seismic-processing software. Much of the information specific to the data are contained in the headers of the SEG-Y format files. The file system format is ISO 9660 which can be read with DOS, Unix, and MAC operating systems with the appropriate CD-ROM driver software installed.
Purpose:
In 1995, the USGS Woods Hole Field Center, in Cooperation with the U.S. Army Corps of Engineers, began a program designed to map the seafloor offshore of the New York-New Jersey metropolitan area; the most heavily populated, and one of the most impacted coastal regions of the United States. The ultimate goal of this program is to provide an overall synthesis of the sea floor environment, including surficial sediment texture, subsurface geometry, and anthropogenic impact (e.g. ocean dumping, trawling, channel dredging), through the use and analysis of sidescan-sonar and subbottom mapping techniques. This regional synthesis will support a wide range of management decisions and will provide a basis for further process-oriented investigations.

Process_Description:
The subbottom data were recorded on the ISIS data acquisition system in QMIPS format. Chirp subbottom channel extracted from raw QMIPS format sonar files and converted to 16-bit Int. SEG-Y format using the program QMIPSTOSEGY. The fish depth was recorded in two-way time (ms) in the delay field (byte 109) of the SEG-Y trace header.

Process_Description:
The metadata from the Open-File report was edited to remove errors as well as update some information. Edits include updating the citation section with the OFR information, added supplemental information with link to the field activity page on CMGDS, change the use and access constraints to none, added the USGS Thesaurus and ISO 19115 Topic Category thesaurus, added keywords section with USGS persistent identifier as theme keyword, fixed information in the NAD83 horizontal coordinate system and the grid system, used a generic email address in metadata, updated digital transfer information, replaced distribution liability with FSP statement. Other blank fields were deleted. The metadata date (19970408), but not the contact (except email) 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.
