Technologies, knowledge and capital : towards a political ecology of the Hake Trawl Fishery Walvis Bay, Namibia
… in the dialogue between trans-disciplinary coastal ecology studies. This dissertation seeks to contribute to the integration of these knowledges, and emphasises the involvement of fishers, communities, and research in informing policy.

Understanding the Impacts of Freshwater Fluxes on the Biogeochemistry of the Coastal Arctic: A Case Study of Prudhoe Bay
… shifts have profound implications for Arctic coastal ecology and biogeochemical cycles. This study, focusing on Alaska's North Slope, explores the influence of freshwater fluxes on water optical properties, vital for accurate satellite remote sensing interpretations. Our approach combined …

Relative sea-level rise and the development of channel-fill and shallow-water sequences on Cape Cod, Massachusetts
… tract composed of a consistent sequence of coastal embayment and shoreline facies that have succeeded one another in response to Holocene relative sea-level rise. As relative sea-level flooded these paleo-channels, marsh environments were established in response to rising relative sea-level. …

A field investigation of diffusion within a submerged plant canopy
… of pollutants and nutrients bound for the coastal ocean. The transport, dilution, and deposition processes occurring within the marsh are key factors in determining this interception, and these are in turn determined largely by tidally driven flows as influenced by marsh vegetation and …

Guidelines for a Comprehensive Mitigation Management Plan for Texas Coastal Wetlands
In support of the Texas Coastal Management Program, guidelines were developed to assist resource agency decision-makers develop and implement a future comprehensive mitigation management plan for Texas coastal wetlands. Current coastal wetland protection and mitigation strategies that are used in …

The synecology of dense assemblages of the deposit-feeding Polychaete, Axiothella rubrocincta (Maldanidae)
<p>Interspecific interactions have been shown to play critical roles in determining the realized niches of species in marine rocky intertidal (ie Connell 1961, Paine 1966,, Dayton 1971) and terrestrial (i.e~ Harper 1969, Pianka 1973, Cody 1974) communities. In contrast, such interactions have not …

Intertidal Seagrass Meadows in South West England: The Ecology of Expansion
Within the space of a decade, intertidal sediments in the Tamar estuary, South West England, have undergone a shift from unvegetated mudflats to dense perennial seagrass habitat. Yet despite the increasing prevalence of intertidal seagrass meadows in the South West, there are large knowledge gaps …

Factors influencing the nursery dynamics of juvenile bull sharks in two estuaries along the Texas coast
Nursery habitats provide refuge for juvenile organisms to grow and develop, and are utilized by several shark species, including bull sharks (Carcharhinus leucas). Bull sharks utilize estuaries adjoining the Gulf of Mexico as nursery habitat, and are the most abundant shark species found along the …

Modeling Nutrient and Plankton Processes in the California Coastal Transition Zone
… models have been developed for the California Coastal Transition Zone (CTZ) region with the overall objective of understanding and quantifying the processes th at contribute to the spatial and temporal development of nutrient and plankton distributions in the CTZ. The first of these models …

Eco-engineering of coastal infrastructure: A design for life
Coastal urbanisation has driven humans to build artificial defences to protect infrastructure from rising sea level, erosion and stormier seas. Artificial structures are proliferating in the coastal and marine environments (“ocean sprawl”), resulting in a loss of natural habitat, species diversity …

Distribution of Foraminifera and Pollen in Coastal Depositional Environments of the Southern Delmarva Peninsula, Virginia, U.S.A.
<p>The coastal zone of the southern Delmarva Peninsula exhibits a wide variety of barrier island system subenvironments. This study investigates whether 20 <em>a priori</em> subenvironments can be distinguished from each other on the basis of abiotic environmental variables, pollen assemblages, …

Stable isotope ecology of South African kelp forests
Kelp forests are some of the most productive coastal ecosystems in the world and provide numerous ecosystem goods and services. Where they occur, they play a key role in coastal ecology and local fisheries. In South Africa, Ecklonia maxima and Laminaria pallida form kelp forests which support …

A radiocarbon method and multi-tracer approach to quantifying groundwater discharge to coastal waters
Groundwater discharge into estuaries and the coastal ocean is an important mechanism for the transport of dissolved chemical species to coastal waters. Because many dissolved species are present in groundwater in concentrations that are orders of magnitude higher than typical river concentrations, …

The Causeway: Bridging Disaster Relief, Recovery, and Climate Adaptation in the Anton Ruiz Watershed
… storms, the future of Punta Santiago and other coastal communities worldwide will necessitate strategies ranging from nature-based shore protection systems, coastal setbacks, and managed retreat. This thesis investigates the time disparate processes of disaster relief, recovery, and climate …

Sources and supply of kelp detritus : quantifying mechanisms of production
In temperate waters, rocky reefs dominated by extremely productive kelp beds export considerable primary production. Despite the extensive body of work on kelp detritus as a trophic subsidy, many questions remain about the production of this detritus. The aim of this thesis was to determine the …

GIS Modeling of Wetlands Elevation Change in Response to Projected Sea Level Rise, Trinity Bay, Texas
… changes in elevation and shoreline position of coastal wetlands in Trinity Bay, Texas, in response to projected sea level rise. The study combines numerical modeling and a geographic information system. A smoothing technique is used on a United States Geographical Survey (USGS) digital elevation …
