A Change in Fish Assemblages in the Pascagoula River, MS
<p>The Pascagoula River in southeastern Mississippi is the largest remaining un-impounded river system in the contiguous United States and have seen a change in fish assemblages over time. Examination of long-term fish assemblage data show that the mainstem Pascagoula River and its two major …

Geomorphic Assessment and Flow Modeling of Pearl Darter (Percina aurora) Habitat in the Pascagoula River Watershed
… threatened species that only resides in the Pascagoula River watershed. Despite its status, habitat preference remains unclear. To fill this knowledge gap, I developed a novel approach to summarizing morphological characteristics of over 500 sandbars across 3 tributaries and mainstem of the …

Gulf Sturgeon of the Pascagoula River: Post-Katrina Assessment of Seasonal Usage of the Lower Estuary
<p>The Pascagoula watershed likely offers the greatest possibility for the survival of the Gulf sturgeon, <em>Acipenser oxyrinchus desotoi</em> within Mississippi. The focus of this project was to determine the routes Gulf sturgeon take through the lower Pascagoula River which splits at river …

Population Parameter Estimation and Stable Isotope Analysis of Gulf Sturgeon (Acipenser oxyrinchus desotoi) in the Pascagoula River
… by stable isotope analysis for GS natal to the Pascagoula River. Pascagoula River GS were captured with anchored gill nets, tagged, and had blood and muscle samples taken between April–November from 2013–2020. Mark-recapture modelling revealed a steadily increasing GS abundance between 2013–2020 …

Detecting Coastal Marsh Change from Aerial Imagery using Spectral and Textural Methods: Pascagoula River Estuary, Mississippi, 1955-2014
… extent of intertidal marsh at the mouth of the Pascagoula River in Jackson County, Mississippi to determine whether marsh extent changed during the period 1955-2014 and to ascertain rates of change. Marsh extent was mapped at 3 meters GSD using spectral and textural aerial image data for image …

Spatial and Seasonal Patterns of Above- and Belowground Vegetation Biomass and Potential Drivers in the Pascagoula River Delta, MS
… called a marsh organ. The West Channel of the Pascagoula River contained significantly higher belowground biomass than the East Channel, which is more anthropogenically modified. Vertical distribution of belowground biomass did not strongly vary between seasons or channels. Elevation was …

An Assessment of the Diverse Freshwater Turtle Fauna of Mississippi
… in both lotic and lentic environments from the Pascagoula, Pearl, Tombigbee, and Mississippi River drainages and were shown to vary among habitat types and between drainages. In addition to the statewide assessment of distributions and abundances, the Indicators of Hydrologic Alteration software …

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
… habitats in the Mississippi Sound, and the Pascagoula River from 2016–2022. This study is the first to document and quantify western and eastern river system GS within the Mobile Bay Estuary. This study also compared habitat use of barrier islands within the Mississippi Sound pre- and …

Spatial Ecology and Movement Patterns of Black Drum (Pogonias cromis) and Sheepshead (Archosargus probatocephalus) in Mississippi Sound
… spawning migrations. Black Drum tagged in Pascagoula River Estuary exhibited broader movements and higher inter-subsystem transition frequencies compared to St. Louis Bay-tagged individuals, highlighting spatial variability in connectivity. Network analyses identified Pascagoula River …

Freckled Darter (Percina lenticula) And Other Fishes’ Usage Of Wood Pile Habitat
… records of <em>P. lenticula</em> in the Pascagoula and Pearl River drainages to assess the status of the species and environmental predictors and species associations. We assessed wood pile size and complexity for differences in fish abundance, species diversity and evenness. We also …

Locality of Topographic Ground Truth Data for Salt Marsh Lidar DEM Elevation Bias Mitigation Using Machine Learning
… elevations near St. Marks, Florida (n=377) and Pascagoula, Mississippi (n=610). These elevations, along with lidar elevations and Sentinel-2A multispectral satellite imagery (MSI) reflectance values were used to train the RF salt marsh DEM adjustment models and apply them under two scenarios: …

Sub-Pixel Classification of Historical and Current Marsh Habitat For the Eastern Mississippi Gulf Coast Using Remotely Sensed Images
… years (1984-2011) for the Western Lower Pascagoula River Basin. The other main objective was to complete an analysis of how the estuarine emergent marsh has changed during this historical time series. Landsat (medium resolution) and Quickbird (high resolution) imagery will be utilized to …

Holocene Formation and Evolution of Horn Island, Mississippi, USA
… storms, and antecedent geology. The Biloxi and Pascagoula incised valleys converge at Horn Island and have played a profound role in the evolution of the system. Within the incised valleys, numerous shallow paleochannels between 4 and 9 meters below sea level exist only on the landward side of …
