Seasonal Variation in Benthic Community Structure in Mobile Bay, Alabama.
The community concept in benthic marine ecology has long been a subject of intense interest. Peterson (1918) was one of the first investigators to recognize and attempt to characterize benthic com- munities in his extensive surveys of the Skagerrak and Baltic Sea. According to Thorson (1957), …

Habitat use of Gulf Sturgeon (Acipenser oxyrinchus desotoi) in Pascagoula River holding areas and in estuarine and marine environments including Ship Island, Mississippi and Mobile Bay, Alabama
… on the location of their natal river relative to Mobile Bay. Tracking of GS movements using acoustic telemetry has occurred since the late 1990s but has increased in use since 2015 for monitoring important habitats that GS rely on throughout their lifetime. For this study, tagged GS were monitored …

Development and Employment of Environmental DNA Methods for the Detection of Bull Sharks (<i>Carcharhinus leucas</i>) in a Freshwater and Estuarine Interface in the Mobile-Tensaw Delta and Mobile Bay, Alabama
… Sharks (<em>Carcharhinus leucas</em>) are highly mobile predators that rely on estuaries and freshwater rivers for maturation, resources, and refuge; their ability to withstand changing environmental conditions may mean they are linking ecosystems through their habitat usage and movements. Rather …

The use of geophysical methods for dam seepage investigations and dredged oyster deposit characterization
… uses to characterize dredged oyster deposit in Mobile Bay, Alabama. The results of the study were expected to be used in assessing the suitability of the dredge location and other similar locations in the bay as potential sites for the deposit of dredge materials presently removed from the …

Analysis of Factors Controlling the Distribution of Trace Elements in Surface Sediments of Coastal Alabama
… samples were collected on a 4 km grid from Mobile Bay, the eastern Mississippi Sound, and bays and rivers adjoining these water bodies. The sediment samples were analyzed for mineralogy and the extractable concentrations of 28 chemical elements (Al, As, B, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, …

Influence of Natural and Anthropogenic Environmental Variability on Larval Fish Diet, Growth, and Condition in the Northcentral Gulf of Mexico
… sources including the Mississippi River and Mobile Bay, among other sources. Early life history stages of fishes are especially vulnerable to environmental variability created by freshwater discharge. The objectives of this study were to describe the available prey field, diet, growth and …

Filling Conservation Gaps For Gulf Sturgeon (Acipenser desotoi) Using Specialized Acoustic Transmitters
… location of their natal river in relation to the Mobile Bay. Acoustic telemetry has been a common method of monitoring GS; however, due to data from this methodology being presence-absence, inferences must be made on why GS are where they are and what they are experiencing there. Recent …

Population Parameter Estimation and Stable Isotope Analysis of Gulf Sturgeon (Acipenser oxyrinchus desotoi) in the Pascagoula River
… FL, in the east with a longitudinal divide at Mobile Bay, AL, creating a western population unit (WPU) and an eastern population unit (EPU). Sturgeon belonging to the WPU exhibit lower abundances, higher mortality rates, and are overall less studied than their EPU counterparts. Notable data …

Nearshore Sedimentology of Eroding Microtidal Estuaries: Bon Secour Bay, Alabama and Perdido Bay, Florida
… estuarine shoreline erosion in Bon Secour Bay, Alabama and Perdido Bay, Florida. Historical aerial imagery compared with modern imagery indicates an average land loss rate of 0.30 – 0.67 m yr-1 at Bon Secour Bay (1992–2018) and 0.55 m yr-1 at Perdido Bay (1994–2018). Selection of these two …

Salinity Transport in a Finite-Volume Sigma-Layer Three-Dimensional Model
… one to the Chandeleurs Islands and the other to Mobile Bay. The baroclinic open boundary and variable friction were implemented in these models. They were calibrated for tides and salinity. The 2008 Bonnet Carré Spillway Opening was applied to the first model. A tidal pumping effect in Lake …

Temporal and Spatial Assessment of PAHs in Water, Sediment, and Oysters as a Result of the Deepwater Horizon Oil Spill
… sites along the Gulf Coast, namely, two sites in Mobile Bay (Denton and Sand Reefs at 1 or 0.1 m above the bay floor), one site near Orange Beach, AL (Perdido), and one near Pointe aux Pines, MS. Water, sediment, and oysters were extracted for quantitation of 24 PAHs by gas chromatography mass …
