This data layer is intended to illustrate the nested model grid G4 (designated with P1 for pit 1, P2 for pit 2, or P3 for pit 3) over which calculations were performed. The analysis results, which are contained in other data layers, are only presented at those locations where model outputs exist (for example, "wet" grid cells, as opposed to "dry" grid cells in the model representing land).There were 128 individual scenarios ran, which were based on significant wave height (H) and mean wave direction (D). Significant wave height was included in eight bins (H1-H8) that ranged from 0 to 6 meters (m), in intervals of 0.5 m and 1 m. There were 16 bins for mean wave direction (D1-D16) that ranged between 0–360 degrees, in intervals of 22.5 degrees. Of the 128 scenarios, 12 were run where no events were observed so these were excluded from the data release.20140710ground conditionAs needed-89.2322136333544-89.042163379857129.522425317175929.4216387757958NoneU.S. Geological SurveyUSGSSt. Petersburg Coastal and Marine Science CenterSPCMSCwavesborrow pitsestuariescoastalISO 19115 Topic Categoryoceanselevationgeoscientific-InformationUSGS Thesaurusmarine geologygeomorphologytopographybathymetrymarine sediment transportGeographic Names Information System (GNIS) ContentGulf of MexicoLouisianaNorth AmericaUnited StatesBreton IslandNone.Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution.
