Archive of Chirp Subbottom Data Collected During USGS Cruise MGNM 00014, Central South Carolina, 13-30 March, 2000, USGS/OFR 00-462

In November 1999, the U. S. Geological Survey, in cooperation with
Coastal Carolina University, began a program to produce geologic maps
of the nearshore regime off northern South Carolina, utilizing high
resolution sidescan sonar, interferometric (direct phase methods)
swath bathymetry, and seismic subbottom profiling systems. The study
areas extends from the ~7m isobath to about 10km offshore (water
depths <12m). The goals of the investigation are to determine regional
scale sand resource availability needed for planned beach nourishment
programs, to investigate the roles that the inner shelf morphology and
geologic framework play in the evolution of this coastal region, and
to provide baseline geologic maps for use in proposed biologic habitat
studies.

This CD-ROM contains digital high resolution seismic reflection data
collected during the USGS MGNM 00014 cruise. The coverage is the
nearshore of central South Carolina. 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.
