Abstract:
Scientists from the U.S. Geological Survey, St. Petersburg Coastal and Marine Science Center conducted a seasonal collection of surficial sediments from Chincoteague Bay and Tom's Cove, located between Assateague Island and the Delmarva Peninsula in March/April 2014 (2014-301-FA) and October 2014 (2014-322-FA). The sampling efforts were part of a larger U.S. Geological Survey study to assess the effects of storm events on sediment distribution. The objective of this study was to characterize the sediments of Chincoteague Bay in order to create baseline conditions to incorporate with hydrodynamic and sediment transport models in order to evaluate pre- and post-storm (Hurricane Sandy) change. This report serves as an archive for sedimentological data derived from the surface sediment. Data are available for a seasonal comparison between March/April 2014 and October 2014. Downloadable data are available as Excel spreadsheets (sediment samples) and as JPEG files (maps). Additional files include: detailed results of sediment grain size analyses, and formal Federal Geographic Data Committee metadata (data downloads).
Purpose:
The file includes all critical stress threshold calculations from the median grain-size of the lagoonal surface sediments collected in Chincoteague Bay in March/April and October 2014 by the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center as well as preliminary model bottom shear stress values from the Woods Hole USGS office.
Supplemental_Information:
This publication contains data for two field activities conducted in 2014: Spring March 26 – April 4 (2014-301-FA), 2014; and fall October 21 – 30, 2014 (2014-322-FA).

Process_Description:
Critical stress thresholds (τcr) for the surface sediments of Chincoteague Bay were calculated using the grain-size data for the surface sediments collected during the spring and fall sampling trips of 2014 following the procedure of Soulsby (1997) as τcr = θcr (ρs - ρ) d50 where θcr is the critical Shields parameter, ρs is the density of sediment (estimated to be 2,650 kilograms per cubic meter [kg/m3]), ρ is the density of seawater (1,027 kg/m3), and d50 is the median grain-size for an individual sample.

Process_Description:
The critical Shields parameter is calculated from a dimensionless sediment parameter, D*, as θcr = 0.30/(1+1.2D*) + 0.055 [1 – exp (-0.020D*)] with D* defined from the kinematic viscosity (v, taken as 1.36 × 10-6 meters squared per second [m2/s]) and uses gravity (g, 9.81 meters per second squared [m/s2]) as D* = d50 [g([(ρs )⁄ρ]-1)/v^2 ]^(1/3).
