Archive of Sidescan-Sonar Data and DGPS Navigation Data Collected During USGS Cruise ATSV 99045 North Carolina Coast, NC, 7-27 October, 1999

In 1999, the USGS began developing a cooperative mapping program in
North Carolina, with collaborators at the North Carolina Geological
Survey (NCGS), and academic institutions. The goal of the program is
to develop a refined understanding of the regional geological
framework and non-living resources of the North Carolina coastal area,
including the emerged and submerged portions of the Coastal Plain. The
USGS Coastal and Marine Geology Program is focusing on nearshore
morphologic evolution (using LIDAR), short-term shoreline change (with
SWASH), and with the present cruise, collecting data on the geologic
framework of the shoreface and inner continental shelf. The goal of
the inner shelf mapping program is to provide a regional synthesis of
the seafloor environment, including a description of sedimentary
environments, sediment texture, seafloor morphology, and shallow
stratigraphy to aid in understanding the long- and short-term
evolution of the coastal system, the form and distribution of sand and
gravel resources, and to provide a basis for sediment dynamics
studies.
