Sediments off the eastern United States vary markedly in texture - the size, shape, and arrangement of their grains. However, for descriptive purposes, it is typically most useful to classify these sediments according to their grain-size distributions. Starting in 1962, the U.S. Geological Survey (USGS) and the Woods Hole Oceanographic Institution (WHOI) began a joint program to study the marine geology of the continental margin off the Atlantic coast of the United States. As part of this program and ...

ECSTDB2005 - U.S. Geological Survey East Coast Sediment Texture Database (2005)

This sediment database contains location, description, and texture of samples taken by numerous marine sampling programs. Most of the samples are from the Atlantic Continental Margin of the United States, but some are from as diverse locations as Lake Baikal, Russia, the Hawaiian Islands region, Puerto Rico, the Gulf of Mexico, and Lake Michigan. The database presently contains data for over 23,000 samples, which includes texture data for approximately 3800 samples taken or analyzed by the Atlantic ...

Archive of side scan sonar and bathymetry data collected during USGS cruise 06FSH01 offshore of Siesta Key, Florida, May 2006.

This data set contains swath bathymetric data collected during USGS cruise 06FSH01 aboard the R/V G.K. Gilbert. A side scan sonar, bathymetric, and high-resolution seismic-reflection survey was conducted off Sarasota, FL to describe the relationship between the sediments and morphology of the inner shelf and adjacent shoreface. These data are part of the Florida Shelf Habitat (FLaSH) map project. For more information on the seismic surveys see http://walrus.wr.usgs.gov/infobank/g/g106fl/html/g-1-06 -fl ...
