During the Deepwater Horizon spill, some oil that reached the surf zone of the northern Gulf of Mexico mixed with suspended sediment and sank to form sub-tidal mats. If not removed, these mats can break apart to form SRBs and subsequently re-oil the beach. A method was developed for estimating SRB mobilization and alongshore movement. A representative suite of wave conditions was identified from buoy data for April, 2010, until August, 2012, and used to drive a numerical model of the spatially-variant alongshore currents. Potential mobilization of SRBs was estimated by comparing combined wave- and current-induced shear stress from the model to critical stress values for several sized SRBs. Potential alongshore flux of SRBs was also estimated to identify regions more or less likely to have SRBs deposited under each scenario. This methodology was developed to explain SRB movement and redistribution in the alongshore, interpret observed re-oiling events, and thus inform re-oiling mitigation efforts. Purpose: This GIS layer contains the model grid used for calculation of waves and currents in the tidal scenarios used to investigate hydrodynamic variability in the northern Gulf of Mexico. This data layer is intended to illustrate the complete model grid over which calculations were performed. The analysis results, which are contained in other data layers, are only presented at those locations where model output exist (e.g., "wet" grid cells, as opposed to "dry" grid cells in the model representing land). Supplemental_Information: This data layer is a subset of USGS Open-File Report 2012-1234, Hydrodynamic and Sediment Transport Model Application for OSAT3 Guidance. It presents the model grid over which hydrodynamic scenario calculations were conducted.

Within the Delft3D model, these coordinates are in UTM, which have been converted into latitude and longitude for this data layer. Logical_Consistency_Report: No duplicate features are present. All polygons are closed, and all lines intersect where intended. No undershoots or overshoots are present. Completeness_Report: This layer contains the complete model grid (including wet and dry, e.g., land, grid cells) used for calculation of tidal hydrodynamic results. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: This layer contains the model grid over which hydrodynamic tidal results were calculated. The native grid used in the Delft3D model is in UTM coordinates, which have been converted to latitude and longitude, therefore there may be slight differences in values as a result of loss of significant figures. Lineage: Process_Step: Process_Description: The Deltares Delft3D numerical model suite (version 4.00.01) was used to create this model grid. Within the Delft3D model, grid cell locations are used in UTM coordinates. The coordinates were exported in latitude and longitude format from the Delft3D model into Mathworks .mat format.

The shapefile is written with the "shapewrite" command. Because MATLAB does not assign a projection, the projection corresponding to the projection associated with the bathymetry used in the numerical models is added in ArcCatalog 9.3. The file was then quality checked in ArcMap to insure values were properly exported to the shapefile from MATLAB.
