Oysters 2011 - Gulf of Mexico

1985 Gulf of Mexico Atlas abstract American oyster Crassostrea virginica Ostion americanoDescription Range: The American oyster, a bivalve mollusc of the family Ostreidae, is found in the western Atlantic from the Gulf of St. Lawrence to the Yucatan Peninsula. In the Gulf, this species occurs throughout estuaries, shallow nearshore waters, and on reefs located near river mouths. Habitat: Large populations of this benthic invertebrate are found in the large estuarine bays and sounds of the Gulf (with most concentrations found within 10-meter depths). Sedentary in character, this invertebrate attaches in clusters to shell reefs, firm mud/shell bottoms and other hard substrates. Feeding and Behavior: The American oyster...

Dynamic Five-Zone Salinity Scheme - Gulf of Mexico

This is an ArcGIS shapefile which depicts the seasonal salinity dynamics of 32 Gulf of Mexico estuaries. To characterize the dynamic nature of estuarine salinity gradients, a multivariate methodology (Bulger et al. 1993) was applied to derive five bio-salinity zones in four salinity seasons for 32 Gulf of Mexico estuaries (Christensen et al. 1997). This seasonal salinity zone spatial framework built upon and refined earlier studies which characterized salinity on an annual-averaged basis (NOAA 1985, Orlando et al. 1993, NOAA 2007). Precipitation, flow gage data, and monthly salinity averages were evaluated to determine which months would be used to represent the high, low, and transitional (increasing and decreasing)...

Submerged Aquatic Vegetation - Gulf of Mexico

This data represent a compilation of seagrass information for areas along the Alabama, Florida, Mississippi, and Texas coasts from various source agencies. Seagrass areas were mapped from aerial photography taken between 1987 to 1999. The original source data were not all classified in the same manner, but the information from each of these sources was maintained in the final results.
