This CD-ROM contains digital high resolution seismic reflection data
collected during the USGS Diane G 97032 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.
This project will generate reconnaissance maps of the sea floor 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 surveys will provide an overall synthesis of the sea floor environment, including seabed texture and bed forms, Quaternary strata geometry, and anthropogenic impact (e.g., ocean dumping, trawling, channel dredging). The goal of this project is to survey the offshore area, the harbor, and the southern shore of Long Island, providing a regional synthesis to support a wide range of management decisions and a basis for further process-oriented investigations. The project is conducted cooperatively with the U.S. Army Corps of Engineer (USACE).
For more information on the seismic surveys see https://cmgds.marine.usgs.gov/fan_info.php?fan=1997-032-FA
These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.

SEG-Y
The SEG-Y files were plotted onboard ship using SIOSEIS seismic processing software
archive of SEG-Y format seismic data The following lines were acquired with the boomer system: 1-10, 42-101, 123-173. The following lines were acquired with the sparker system: 11-20, 22-41, 108-111, 114-118, 121-122. No seismic data were collected on the following lines: 21, 102-107, 112-113, 119-120.
The ship was navigated with differential GPS
10
DGPS is assumed to be accurate within 5-10 meters
The vertical position was local sea level and there was no correction to a datum
The subbottom data were recorded on the Mudseis data acquisition system in SEG-Y format. The conversion program processSegy was used to renumber the traces as trace 1 or traces 1 and 2 for 2-channel data and fill out the SEG-Y EBCDIC reel header. Traces were renumbered because the Mudseis system begins with trace 0 instead of 1. The data were filtered with a low pass of 300 Hz and a high pass of 3000 Hz at the acquisition step along with a 48 db gain.

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 include: adding ISO keywords, fixing the UTM zone number to match the data acquisition location and central longitude; changed the title to reflect sparker data, added information about which lines were collected with the boomer system and the sparker system, added information for line numbers that had no seismic data, added the decimal to the denominator of flattening ratio in the geodetic model, and indicated the data are now on DVDs instead of CD-ROMs in addition to the online option.

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. Minor edits were made to the standard order section. 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. Additional edits were probably made to the original metadata by someone else who did not document what they changed.

The data were acquired using an ORE/ Huntec boomer seismic profiling system. A Geopulse or Huntec electro-mechanical source was used. ITI and Benthos streamers were the receivers. Seismic data were logged digitally with the Mudseis acquisition system. The SEG-Y data were checked for quality with SEISUNIX seismic processing software and are archived on this CD-ROM. The SEG-Y format is described in detail by Barry and others (1975). The files are in standard 16-bit integer SEG-Y format. The SEG-Y files consist of shot files with one or two traces per shot depending if one or two channels were recorded. Channel one was an ITI streamer and channel 2 when recorded was a Benthos streamer. There are 1600 samples per trace. The sample rate was 0.125 ms which resulted in a trace length of 200 ms. The boomer was fired at a rate of 0.5 seconds.
