Land Loss: Attachment, Place and Identity in Coastal Louisiana
… explores the identity loss that residents of coastal Louisiana experience due to coastal land loss. I rely on 126 in-depth interviews of residents from communities in six coastal parishes (counties). Respondents convey the meanings they give to land loss through constructing a narrative of …

Abrupt Climate Change and Storm Surge Impacts in Coastal Louisiana in 2050
… surge responses along the coast of the State of Louisiana. Surge responses are quantified for storms that could potentially occur under present climate but 50 years into the future on a coast subjected to current erosion and local subsidence effects. Analyses of projected hurricane intensities …

The Social Construction of Loss and Grief: Experiences of Coastal Louisiana Residents
… of the community of Boothville-Venice, Louisiana, and examining their narratives for an understanding of loss. This thesis uses symbolic interactionism, and draws from existing literature in psychology, thanatology, and sociology to develop the understanding of loss and grief. The …

Patterns and Pathways of Wetland Sedimentation and Landscape Change in Coastal Louisiana
<p>Coastal Louisiana wetlands exist in a dynamic physical environment and retracted dramatically in the last century. Here I examine the spatial and temporal variability of this landscape with an emphasis on the interactions between anthropogenic landscape modifications and geological …

Analysis and modeling of hurricane impacts on a coastal Louisiana lake bottom
… but little is known about the response of coastal lakes to storm events. For the first time, tropical cyclone impacts on a shallow coastal lake in the Louisiana coastal plain have been studied using direct lines of evidence and numerical modeling. Using side-scan sonar, CHIRP subbottom and …

Oligohaline wetland response and recovery following storm-driven saltwater intrusion in coastal Louisiana
Coastal ecosystems occupy an interface between land and ocean, making them vulnerable to a variety of natural and anthropogenic disturbances. Large, episodic disturbances (mega-disturbances) cause immediate and long-lasting changes to coastal wetland plant communities and soils by changing the …

Landscape analysis of vegetation change in coastal Louisiana following hurricanes Katrina and Rita
Investigations of hurricane disturbances on coastal vegetated communities are common, but relatively few are comprehensive across broad geographic regions. The 2005 hurricanes, Katrina and Rita, exposed Louisiana coastal landscapes to physical modifications and extensive and prolonged flooding, …

Effects of Hurricane Disturbance on the Stopover Ecology of Intercontinental Landbird Migrants in Coastal Louisiana
… change, hurricanes, sea level rise, and coastal subsidence have greatly reduced the amount of coastal forest in this region, which may affect the stopover biology of migratory birds. In southwestern Louisiana, coastal cheniere forests are the first possible landfall for birds returning …

Mat Movement in Coastal Louisiana Marshes: Effect of Salinity and Inundation on Vegetation and Nutrient Levels
<p>The present research compared and contrasted the physical structure of floating and rooted marshes, their differing responses to open-water salinities and inundation, as well as the nutrient distribution in the porewaters and sediment. The effects of the physical differences in the two marsh …

The ecology of two estuarine-dependent tonguefishes, the blackcheek tonguefish (Symphurus plagiusa) and the offshore tonguefish (S. civitatium), in coastal Louisiana
The pattern and process of wetland loss in coastal Louisiana has the potential to influence the distribution and abundance of fishes and macroinvertebrates that utilize inshore estuarine habitat as nurseries during their early life histories. Current management plans designed to stabilize marsh …

Assessing Hydrologic Connectivity using Water Temperature, Wax Lake Delta, Louisiana
… island on the Wax Lake Delta of coastal Louisiana. We deployed a relatively inexpensive, open-source data logging platform to collect high quality continuous water temperature, water depth, air temperature, and shortwave solar radiation from a portion of Wax Lake Delta from …

The Rise and Fall of the Louisiana Muskrat, 1890-1960: An Environmental and Social History
… century drew to a close, people living in coastal Louisiana noticed that local rodents called muskrats were rapidly increasing and quickly becoming pests by digging up crops and into levees. Property owners soon demanded their elimination, but to the ire of many, Louisiana officials chose …

The Influence of Flooding on Contributions of Spartina Alterniflora Roots to Salt Marsh Soil Volume in a Field Setting
Rapid rates of coastal wetland loss in Louisiana are widely recognized. One important question of wetland sustainability is how volumetric contributions of roots to wetland soils vary under the influence of different hydrologic regimes. The research presented here specifically investigates the …

Estuarine Dynamics as a Function of Barrier Island Transgression and Wetland Loss: Understanding the Transport and Exchange Processes
The Northern Gulf of Mexico and coastal Louisiana are experiencing accelerated relative sea level rise rates; therefore, the region is ideal for modeling the global affects of sea level rise (SLR) on estuarine dynamics in a transgressive barrier island setting. The field methods and numerical …

An Examination: Using Participatory Action Research in a Marginalized Coastal Community at Risk to Natural Hazards
… Action Research (PAR) in a small, marginalized coastal community at risk to natural hazards. PAR is a method of conducting high-quality research to support the social change goals of diverse cultural and ethnic communities, especially as they relate to community involvement, democracy, …

The Biology of Spaeroma Terebrans in Lake Pontchartrain, Louisiana with Emphasis on Burrowing
… Pontchartrain near the Bonnet Carre Spillway, Louisiana. In addition laboratory experiments for water column distribution and substrate preferences were conducted using cypress, Styrofoam, and balsa. Results indicate that this population may be parthenogenic and that wood or material hardness …

Soil Buoyancy as a Potential Indicator of Hurricane Susceptibility in Louisiana Marshes
… rapidly destroy large expanses land in coastal Louisiana marsh. Research shows that freshwater marsh with organic soils experience increased destruction during hurricanes compared to other marsh. A relevant question surfaces, do some restoration projects create marsh similar to marshes …

Linkages between Marsh Fragmentation, Prey Availability, and Blue Crab (<i>Callinectes sapidus</i>) Abundance and Mortality
<p>Coastal marshes are important nursery habitats for many commercially important invertebrate species, yet these marshes are being lost worldwide at an unprecedented rate due to subsidence, erosion, climate change, and human activity. As marsh is lost, it creates the opportunity for submerged …

Coastal Wetland Dynamics Under Sea-level Rise and Wetland Restoration in the Northern Gulf of Mexico using Bayesian Multilevel Models and a Web Tool
… restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, …

An Assessment of the U.S. Army Corps of Engineers' Environmental Plan Evaluation Methods
… of New Orleans, but contributed to land loss in coastal Louisiana, and by some accounts, made the population more susceptible to hurricane damage. The agency has now embarked on a mission to restore some of the damaged environmental areas. This dissertation evaluates whether policies and …
