Hydrodynamics and freshwater diversion within Barataria Basin
… to understand the physical processes in the Barataria estuary, a previously developed two-dimensional, depth-integrated hydrodynamic model is applied to simulate estuarine processes. The equations for conservation of mass and momentum predict specific physical processes when forced by tidal …

Water Quality Modeling of Freshwater Diversions in the Barataria Basin
… salinity and nutrient concentration of the Barataria Basin over a 2 period is presented here. The model predicts that the salinity of Lower Barataria decreases with the introduction of freshwater diversions. The model also predicts that nutrient concentration increases in Barataria Basin and …

Modeling the impacts of pulsed riverine inflows on hydrodynamics and water quality in the Barataria Bay estuary
… hydrodynamics, salinity and water quality in the Barataria estuary, a deltaic estuary in south Louisiana. This estuary receives freshwater and nutrient discharges from the Davis Pond diversion, the world’s largest freshwater diversion project. I have implemented two Barataria Bay simulation models …

The ecology of two estuarine-dependent tonguefishes, the blackcheek tonguefish (Symphurus plagiusa) and the offshore tonguefish (S. civitatium), in coastal Louisiana
… of patterns of resource utilization within the Barataria study area identified significant differences between species with respect to microhabitat selection. Offshore tonguefish were generally more abundant than blackcheek tonguefish in the Barataria study area. Blackcheek tonguefish used lower …

Addressing the land loss-fish production paradox
… on historical abundance of estuarine nekton in Barataria Bay, LA is lacking. I first examined the differences between fishery independent and fishery dependent data as indices of relative abundance. Previous studies used landings data to evaluate the importance of marsh habitat (e.g. distance of …

Detection of PAHs in Commercial and Wild Caught Fish Oil using Scanning Fluorescence Spectroscopy
… Bay, NJ, James River, VA, Vermillion Bay, LA and Barataria Bay, LA in 2010 and/or 2011. Barataria Bay received heavy oiling from the DWH spill from April to August 2010. Vitamins and PAH standards were bought commercially. The fish oils and standards were analyzed using a SpectraMax M5 which …

Polycyclic Aromatic Hydrocarbon determination in liver of Menhaden exposed to the Deep Water Horizon Oil Spill
… ratio is indicative of petroleum exposure. The Barataria Bay (BB), LA 2010 and 2011 samples, Vermillion Bay, LA 2011 samples, and Delaware Bay, NJ 2010 and 2011 data all showed evidence of PAH exposure. The difference of HNP-like and HPY-like PAHs at BBLA from 2010 to 2011 indicated that the …

Linking nitrogen biogeochemistry to different stages of wetland soil development in the Mississippi River Delta, Louisiana
… River delta. In the older, transgressing Barataria basin, there was no clear effect of the climate-induced species shift from Spartina alterniflora Loisel to Avicennia germinans L. on soil nutrient chemistry. Observed soil development patterns were attributed to allochthonous sediment …

The effects of natural and anthropogenic stressors on the stress response and tissue-level response in teleost fish
Analysis of integrative physiological responses is a valuable approach to studying the biological impacts of natural and anthropogenic stressors in biota. By measuring fluctuations in multiple physiological characteristics, we are able to predict the impact that exogenous stressors may have on …

Quantitative Oil Source-Fingerprinting Techniques and Their Application to Differentiating Crude Oil in Coastal Marsh Sediments
Oil source-fingerprinting is an environmental forensics technique that uses analytical chemistry to determine the origin of oil residues in environmental samples by comparison to a known or suspected source oil. Currently, the only standardized method for oil source fingerprinting is a qualitative …
