The U.S. Geological Survey Sea Floor Stress and Sediment Mobility Database contains estimates of wave-current bottom stress and sediment mobility for the U.S. Atlantic and Gulf Coast continental shelf regions.
This USGS database provides information to address issues in coastal and offshore areas where the degree and/or frequency of sediment mobility are important, such as characterization of sea floor ecosystems and evaluation of areas prior to development.
The estimates contained in the database are designed to spatially and seasonally resolve the general characteristics of wave-current bottom shear stress over the US continental shelf, and to estimate sea floor mobility by comparing the modeled stress to critical shear stress thresholds for initiation of sediment movement at sites where grain size data are available. All stress values are given in Pascals (Pa). The methodology for creating the estimates of bottom stress and sediment mobility contained in this data base may be found in Dalyander and others (2012).
The database is organized by region. Select the region of interest to download files showing previews of results, metadata, and sea floor stress and mobility statistics in Arc polygon and point shapefile format.

The U.S. Geological Survey Sea Floor Stress and Sediment Mobility Database contains estimates of bottom stress and sediment mobility for the U.S. continental shelf. This U.S. Geological Survey database provides information that is needed to characterize sea floor ecosystems and evaluate areas for human use.

SignellCharacterizing wave- and current- induced bottom shear stress: U.S. middle Atlantic continental shelf
Waves and currents create bottom shear stress, a force at the seabed that influences sediment texture distribution, micro-topography, habitat, and anthropogenic use. This paper presents a methodology for assessing the magnitude, variability, and driving mechanisms of bottom stress and resultant sediment mobility on regional scales using numerical model output. The analysis was applied to the MiddlAuthorsP. Soupy Dalyander, Bradford Butman, Christopher R. Sherwood, Richard P. Signell, John L.
