Disclaimer The USGS Coastal and Marine Geology Program (CMGP) produced this data-synthesis report. Limitations are imposed by the nature of the marine setting and datasets (e.g., shallow water with high offshore current velocity, variable seismic-grid spacing and non-linearity of seismic tracklines, and distortion in aerial photomosaic images due to flight path and camera-lens curvature). These limitations preclude CMGP guarantee of precise registration of global coordinates on the maps. The locations of mapped geologic features and environments are believed to be accurate within a few meters. None of the data should be used for navigational purposes. Reference to any specific commercial product, process, or service by trade name, trademark, manufacturer, or otherwise does not necessarily constitute or imply its endorsement, recommendation, or favoring by the United States Government or any agency thereof. continue to: Related Online Publications
