Abstract:
This DVD-ROM contains copies of the navigation and field water gun subbottom data collected aboard the R/V Seaward Explorer, from 7-25 May, 1995. The coverage is in the New York Bight area. This DVD-ROM (Digital Versatile Disc-Read Only Memory) has been produced in accordance with the UDF (Universal Disc Format) DVD-ROM Standard (ISO 9660 equivalent) 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 disk 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 disk should be viewable by all WWW browsers but may not properly format on some older WWW browsers. Also, some links to USGS collaborators and other agencies are available on this DVD-ROM. These links are only accessible if access to the Internet is available during browsing of the DVD-ROM. The archived water gun subbottom data are in standard Society of Exploration Geologists (SEG) SEG-Y format (Barry and others, 1975) and may be downloaded for processing with software such as Seismic Unix or SIOSEIS. DOS and Microsoft Windows compatible software for plotting SEG-Y files (PLOTSEIS) and viewing SEG-Y headers (DUMPSEGY) is located in the PLOTSEIS directory. Processed water gun profiles (GIF images) may be viewed on this DVD-ROM with your WWW browser.
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 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).

Process_Description:
The water gun data was recorded using Xseismics on a MASSCOMP system. Xseismics is a software/hardware package that consisted of Concurrent Computer Corp. Unix based data collection system. This included a 12 bit Analog / Digital converter, an X window display, 8mm tape device, network interface. The software was developed inhouse. This software controlled the data collection system, logged SEGY format seismic data and also displayed seismic data on the X terminal.

Converted the metadata from HTML to a TEXT version using CNS v. 2.8.4 (chew and spit) metadata pre-parser. Once converted used TKME (v 2.8.4) to fix some problems with the metadata. The fixes included: adding ISO keywords, adding a link to the online publication, adding the decimal to the denominator of flattening ratio in the geodetic model.

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.). Attempted to modify http to https where appropriate. Added the Larger Work Citation. 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.

Overview_Description:
Entity_and_Attribute_Overview:
The data were acquired using a 15 cubic inch water gun seismic profiling system. ITI and Benthos streamers were the receivers. Seismic data were logged digitally with the Masscomp/Xsesimics acquisition system. The SEG-Y data were checked for quality with Seismic Unix seismic processing software and are archived on this DVD-ROM. The SEG-Y format is described in detail by Barry and others (1975). The files are in standard 32-bit IBM floating point SEG-Y format. The SEG-Y files consist of shot files of two traces per shot. Channel one was an ITI streamer and channel 2 when recorded was a Teledyne streamer. There are 2048 samples per trace. The sample rate was 0.5 ms which resulted in a trace length of 1024 ms. The water gun was fired at a rate of 5 seconds.

Format_Information_Content:
The SEG-Y standard format (Barry and others, 1975) consists of the following: A 3600-byte reel identification header with the first 3200 bytes consisting of a EBCDIC header block and a 400-byte binary header block. Both headers include information specific to line and reel number. The trace data block follows the reel identification header. The first 240 bytes of each trace block is the binary trace identification header. The seismic data samples follow the trace identification header.
