Resource Abstract:
- description: The U.S. Geological Survey has been characterizing the regional variation in shear stress on the sea floor and
sediment mobility through statistical descriptors. The purpose of this project is to identify patterns in stress in order
to inform habitat delineation or decisions for anthropogenic use of the continental shelf. The statistical characterization
spans the continental shelf from the coast to approximately 120 m water depth, at approximately 5 km resolution. Time-series
of wave and circulation are created using numerical models, and near-bottom output of steady and oscillatory velocities and
an estimate of bottom roughness are used to calculate a time-series of bottom shear stress at 1-hour intervals. Statistical
descriptions such as the median and 95th percentile, which are the output included with this database, are then calculated
to create a two-dimensional picture of the regional patterns in shear stress. In addition, time-series of stress are compared
to critical stress values at select points calculated from observed surface sediment texture data to determine estimates of
sea floor mobility.; abstract: The U.S. Geological Survey has been characterizing the regional variation in shear stress on
