Archive of Chirp Subbottom Data Collected During USGS Cruise DIAN 97032, Long Island, NY Inner Shelf -- Fire Island, NY, 25 September-19 October, 1997

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).

This CD-ROM contains digital high resolution seismic reflection data
collected during the USGS DIAN 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.
