- Abstract:
- 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.
- Purpose:
- 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).

- Process_Description:
- 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.

- Entity_and_Attribute_Overview:
- 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.
