Marine seismic reflection data are used to image and map sedimentary and structural features of the seafloor and subsurface. These data are useful in mapping stratigraphy and in assessing other submarine geologic characteristics and features. These data were collected as part of a Louisiana Sand Resources Study done in cooperation with the University of New Orleans, the U.S. Army Corps of Engineers, and the Louisiana Department of Natural Resources. This study is part of the U.S. Geological Survey (USGS) Subsidence and Coastal Change (SCC) project.
Are there legal restrictions on access or use of the data?Access_Constraints: None. These data are held in the public domain.
Use_Constraints:The U.S. Geological Survey requests to be acknowledged as the originator of the data in future products or derivative research.
