Characterization of Rain and Stormwater Nitrogen Inputs to the Mississippi Sound: A Landscape Approach
… across three different landscape types along the Mississippi Sound (hardened, residential, and pristine), as well as from drainage pipes that flow directly into to the Mississippi Sound. Nitrogen stable isotopes were used to trace the stormwater nitrogen to the surface waters and biota within the …

Investigating Nekton Response to Changing Salinities in the Mississippi Sound: An Experimental and Statistical Approach
<p>The Mississippi Sound provides nursery habitats for many coastal species and is recognized for its commercial fisheries. Previous freshening events linked to the Bonnet Carré Spillway, a Mississippi River flood diversion structure, proved catastrophic for oyster populations in the Mississippi …

Modeling Food Assemblage Dynamics in Western Mississippi Sound Regarding Eastern Oyster (Crassostrea virginica) Larval Performance
<p>Western Mississippi Sound is home to historical eastern oyster reefs that serve as an economically important yet decimated environmental habitat for coastal Mississippi (Pace et al. 2020, Pruett et al., 2024). Previous studies speculate upon the potential of food particle size as a food …

Assessing Respiration Rates and Nutrient Dynamics of Aritifical Reef Biofilms and Bacterioplankton in the Mississippi Sound
… dynamics at four artificial reef habitats in the Mississippi Sound. Biofilm samples were also collected from settlement plates deployed at each site and were analyzed for 813C and 81sN stable isotope content. Respiration rates were always higher in the presence of biofilm but bacterial abundance …

Site Fidelity and Association Patterns of Bottlenose Dolphins (<i>Tursiops truncatus</i> in the Mississippi Sound
… bottlenose dolphins (Tursiops truncatus) in the Mississippi Sound (Sound) over a three-year period (May 2004 - April 2007). Using photoidentification techniques, 74% (n = 498) of the identified dolphins were classified as transients, while 10% (n = 71) were classified as year-round residents, and …

Resident Benthic Fishes of Artificial Reefs in the Mississippi Sound: Effects of Habitat Relief and Subregion
… fishes resident to artificial reefs in the Mississippi Sound, and to link this productivity to the artificial reef community through trophic relationships. This study examined differences in condition of benthic fishes resident to four artificial reefs of two profile types distributed across …

Spatial Ecology and Movement Patterns of Black Drum (Pogonias cromis) and Sheepshead (Archosargus probatocephalus) in Mississippi Sound
… quantity subsystem-level use of these species in Mississippi Sound and assess the extent of individual variability in movement, connectivity, and reproductive-related behavior. Fish were captured across multiple subsystems and tagged with acoustic transmitters to monitor movements from 2021-2025. …

Modeling the Effects of Low-Pressure Atmospheric Fronts on Sediment Transport through Mississippi Sound Barrier Island Inlets
<p>Coastal sediment dynamics in the Mississippi Sound are strongly influenced by tropical cyclones and the more frequent passage of low-pressure atmospheric fronts. While hurricanes are well recognized for reshaping barrier islands and altering sediment budgets, the cumulative role of recurrent …

MULTISPECIES USE OF VARIOUS HABITATS IN THE MISSISSIPPI SOUND WITH AN EMPHASIS ON FUTURE OYSTER REEF CONSTRUCTION
<p>Transient fish have high economic value and effective restoration projects must consider the variable impacts they may have on these fish in addition to the target organism or habitat being restored. Globally, oyster reef construction is common and will continue but data on their impacts to …

The Effect of Boat Type on Bottlenose Dolphin (<i>Tursiops trucatus</i>) Behavior in the Mississippi Sound
… behavior changed in the presence of boats in the Mississippi Sound between 2006 and 2012, and more specifically, to detail how different boat types impacted dolphins’ behavioral states. This study is unique in its capacity to assess the effect of all major boat types in a given area. Common boat …

Bacterioplankton Production in the Western Mississippi Sound and the Role of Photosynthetic Extracellular Release as a Driver of Bacterial Production
… at two separate stations in the western Mississippi Sound (MS). One was an inshore site outside of the Bay of St. Louis and the other site was located in the transition zone (offshore) between the MS and Mississippi Bight, just south of Cat Island. Bacterial production (BP) was analyzed …

Examining the Impact of Bonnet Carré Spillway Opening on Hypoxia Evolution in the Mississippi Sound and Bight: A 2019 Case Study
… of low-salinity, highly polluted water from the Mississippi River into the Mississippi Sound and Bight (MSAB). These events dramatically altered the region's salinity, circulation, and ecological conditions, raising concerns about their role in hypoxia formation. This study uses a …

A Statistical Model for the Prediction of Dissolved Oxygen Dynamics and the Potential for Hypoxia in the Mississippi Sound and Bight
… distress among aquatic organisms. In the Mississippi Sound and Bight, hypoxia is most prevalent from late-spring through late summer. Since hypoxia events can have dramatic effects on coastal fisheries, the spatial and temporal magnitude of hypoxia presents a clear threat to the productive …

Community Structure and Production of the Macrobenthos on Four Artificial Reefs in the Mississippi Sound in Relation to Substrate and Profile Type
<p>In recent years, the Mississippi Department of Marine Resources (DMR) has made a concerted effort to enhance its coastal fishery resources by creating artificial reefs. Through this effort, 73 nearshore reefs have been created across the MS coast. Different substrate types used to construct MS …
