Low Frequency Edge Waves and Their Role In Coastal Dynamics
… scales represent an important part of the coastal ocean response to tidal and atmospheric forcing. A semidiurnal tide traveling over the continental shelf and slope can be propagated by a Hybrid Kelvin-Edge Wave (HKEW), which is the fundamental mode propagating only downstream (Kelvin wave …

Effects of coastal dynamics on colonization of Louisiana wetland plants by fungal endophytes
This dissertation explores the effects of stress and disturbance on fungal endophyte diversity and composition in obligate wetland plants in southeast Louisiana. I explored two types of endophytes: root and foliar. Each of these groups is known to live within apparently healthy host plants without …

Observations and Modeling Forcing Mechanisms for the Coastal Dynamics of the Upper Gulf of Thailand
… the model simulations. The UGOT is a shallow coastal system, ∼1°×1° in size with the average depth of only 15 m. Sensitivity studies evaluate how the dynamics is affected by surface wind stresses, river discharges, and surface heat fluxes. The impact of the low latitudes (∼13 °N) on the …

On the warm bias along the South-West African Coast in coupled models : an oceanic perspective
… biases over the SouthWest African (SWA) coastal region. Recent investigations indicate that coastal ocean dynamics may play an important role in determining the SST patterns, but none of them provide a detailed analysis. In this study, I analyze simulations produced both by coupled models …

Refinement of a Regional Storm Surge Mesh for High-Resolution Topographic Representation of Volusia County
… to Hurricane Nicole, which caused unprecedented coastal damage to dunes and seawalls. The extent of damage that occurred within Volusia and Flagler Counties during the 2022 hurricane season, the underrepresentation of this region within sustainability and resilience research, and the ecological, …

Locality of Topographic Ground Truth Data for Salt Marsh Lidar DEM Elevation Bias Mitigation Using Machine Learning
… elevation models (DEMs) are crucial for modeling coastal salt marsh systems, simulating the coastal dynamics of sea level rise (SLR), and predicting storm surge inundation depth and duration. Improvements in lidar acquisition technology and data processing over the last decade have led to …

SHORELINE DYNAMICS OF SOUTH AFRICA USING SATELLITE IMAGERY
… impedes a holistic understanding of shoreline dynamics amid increasing environmental and anthropogenic pressures. This study addressed this critical knowledge gap by utilising a satellite-derived shoreline algorithm (CoastSat) to rectify years of inadequate monitoring and to contribute to a …

Coastal surface circulation of the Gulf of Cadiz from satellite altimetry measurements
… thesis is to contribute to the understanding of coastal zone dynamics using high-resolution altimetry data. The study evaluates the possibility of studying mesoscale surface circulation in coastal areas, particularly in the Gulf of Cadiz, Spain, using high-resolution altimetry data with a posting …

The Regional Communities of Viking Age Norway and their Contribution to Socio-Political Dynamics, c. 900 - 1050
… narrative of state formation by assessing the dynamics which led to the formation of regional communities, identifying these communities wherever possible, and analysing their role in the gradual change of social and political structures that ultimately saw the emergence of a unified and, to …

The modification of arctic permafrost coastlines
… Arctic will likely result in greater rates of coastal retreat. An increase in coastal erosion would result in dramatic increases in the volume of sediment, organic carbon and contaminants to the Arctic Ocean. These in turn have the potential to create dramatic changes in the geochemistry and …

Coastal and sediment dynamics in a high-energy, rocky environment
A study of the wave dynamics, hydrodynamics and sediment dynamics was conducted at an energetic open-coast site at New Plymouth, New Zealand. The location features large, shore-normal reefs of volcanic agglomerate extending from an irregular shoreline, with “black” volcanic sands intermittently …

Modelling of low- and high-frequency sea level variability and their drivers around the southern African coast
… and improving the incorporation of oceanographic dynamics, underpinning hind- and forecasting models, will remain fundamental to the accurate prediction of physical ocean and coastal dynamics. Numerous recent studies have investigated current and possible future Southern Ocean dynamics. However, …
