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

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.
