The Yoakum Canyon is the largest of the Gulf Coast Eocene erosional gorges and is interpreted as a buried submarine channel. It can be traced for 67 miles from the Wilcox fault zone, which defines the position of the early Eocene shelf edge, nearly to present outcrop. This paper expands on previously published descriptions of the canyon using a more extensive subsurface data base. Decompaction of the canyon shale-fill reveals that original depths of the canyon exceeded 3500 ft (1067 m). Apparent...

Storm surge, the pileup of seawater occurring as a result of high surface stresses and strong currents generated by extreme storm events such as hurricanes, is known to cause greater loss of life than these storms' associated winds. For example, inland flooding from the storm surge along the Gulf Coast during Hurricane Katrina killed hundreds of people. Previous storms produced even larger death tolls. Simultaneously, dune, barrier island, and channel erosion taking place during a hurricane l...

In the past decade, Bald Eagle populations throughout North America have increased considerably and, despite their previous known avoidance of humans, eagles have begun invading cities in large numbers. The overall aim of this study was to document the ecology of urban Bald Eagle populations living in south-coastal British Columbia. We conducted a comparative study of the nest-site characteristics, productivity, and feeding habits of over 150 breeding pairs of rural, suburban and urban eagles. T...

Washover events on coastal headland beaches occur when storm surge from cold fronts, high tides, tropical storms, and hurricanes move across the beach, reworking and depositing sand in the back marshes and shallow mudflat areas. On Fourchon Beach, Louisiana, a 9-mile coastal headland beach impacted by the Deep Water Horizon oil spill, these washover events have intermittently moved oil from the subtidal and intertidal portion of the beach to the supratidal mudflats and marsh areas. In order to d...

The current trend of global populations moving increasingly to high density, coastal cities places a greater emphasis upon the water quality of aquifers supplying those cities. Problems that affect coastal aquifers (e.g. saltwater intrusion, non-point source pollution) will be amplified as this trend increases. The goal of this research project is to understand the processes that control freshwater/saltwater interactions in the coastal zone, specifically in areas of high submarine groundwat...

The northern flying squirrel, Glaucomys sabrinus (Shaw), is an arboreal sciurid inhabiting forested habitats across North America. Hypogeous fruit bodies of mycorrhizal fungi (truffles) are a predominant food eaten by northern flying squirrels. Previous studies have suggested that the abundance of truffles in a stand may be an important factor associated with the density of northern flying squirrels. Over a twoyear period, five second-growth western hemlock (Tsuga heterophylla (Raf). Sarg.)...

The interaction of microorganisms with sediments can enhance their survival by reducing exposure to various stressors and thus marine sediments may act as reservoirs for pathogenic microorganisms. In coastal waters there can be an increased risk of infection to humans due to the possible re-suspension of these microorganisms during recreational activities. This research attempts to more accurately identify environmental exposure in the first stage of a health risk assessment in recreational coas...

Over the past few decades, the development of coastal areas has become an increasingly contested arena. For many years, tourism in remote coastal areas has been the preserve of a few intrepid campers, surfers and recreational fishers. More recently, however, numbers along parts of the coast have increased rapidly, not only contributing to an expansion of camping activity, but also pressure for more commercially oriented tourism. This has contributed to concerns about the environmental sustainabi...

Research was undertaken for this thesis to uncover characteristics of resilient volunteers and stewardship groups, both of which are a major element of the social mobilisation strategy used in Australia to manage natural resources. The ability of volunteers and groups to overcome problems, deal with new issues as they arise, and keep going under pressure is termed 'resilience'. A 'resilience management' approach to natural resource management uses the idea of 'adaptive change' or panarchy to und...

This thesis examines community structure of cliff-top coastal heathlands in Botany Bay National Park, Sydney. Community properties of floristic composition, structure and species richness are investigated. This investigation is made in order to assess the justification for contemporary pre-emphasis in local studies on individual community properties. It is also made in order to assess the relative and independent contributions of individual properties to variance in overall community structure. ...

The IPCC has identified small islands and coastal zones among regions most vulnerable to climate change. The geomorphological characteristics of Prince Edward Island (PEI), such as highly erodible sandstone bedrock and low elevation, contribute to a high degree of physical vulnerability to climate change. The province is highly susceptible to physical impacts of climate change including relative sea-level rise and increased rates of coastline retreat. In order to assess the physical coastal vuln...

A spatial-temporal model is developed for modelling the impacts of simulated coastal zone storm surge and flooding using a combined spatial mapping and system dynamics approach. By coupling geographic information systems (GIS) and system dynamics, the interconnecting components of the spatial-temporal model are used with limited historical data to evaluate storm damage. Overlapping cumulative effects layers in GIS (ArcMap) are used for describing the coastal community’s profile, and a system dyn...

The compact mesocosm which was designed for a laboratory scale was used for the kinetic study of refractory organic compounds in a tidally influenced coastal marsh wetland soil. The tidal cycles were controlled pneumatically using an air chamber inside the mesocosm tank. Phenanthrene as the test compound showed that its degradation in the intertidal wetland soil was faster than that in the subtidal wetland soil. Oxygen resupply during the tidal cycles to the intertidal wetland soil would enhance...

Quantifying resilience is difficulties due to the different definitions of resilience, the interchangeable uses with two other terms vulnerability and adaptability, as well as the lack of consensus on what indicators should be selected to quantifying resilience. This thesis research studied the community resilience in Louisiana by applying the Resilience Inference Measurement (RIM) model at two geographic levels: county level and zip code level. The RIM model accesses resilience by using three d...

The purpose of this study is to analyze the combined effects of storm surge and inland rainfall on the floodplain of a coastal bayou in the Houston area using dynamic hydraulic modeling. HEC-RAS, a one dimensional flow model, was run for both the steady and unsteady states in order to analyze the linkage between inland flooding and storm surge. First, the steady model was run to give a basic understanding of the watershed. The unsteady HEC-RAS model was then evaluated in the unsteady state which...

The seasonal asymmetry in coastal temperatures on Hudson Bay was explored and evaluated as a proxy to hindcast sea ice conditions prior to 1972. Various indices of air temperature difference (∆T) between Churchill, MB and Inukjuak, QC were tested for linear correlations with spatially averaged sea ice concentration (SIC) and ice-free season length (IFS). A multiple regression equation employing a 31-day average of peak ∆T and a 61-day average of temperature during freeze-up reproduced the IFS re...

Land use/land cover (LULC) change and variations in precipitation can alter the quantity and quality of freshwater flows. The Mission-Aransas (M-A) estuary depends on inputs of freshwater and material from streams in order to maintain its ecological integrity. Freshwater inflow estimates for the M-A estuary have been established, but no analyses using scenarios of LULC change and precipitation variability have been conducted that inform how freshwater inflows could be impacted. A land change an...

Eutrophication is one of the greatest threats for the Baltic Sea, and one of its more critical consequences is bottom water hypoxia. Nutrient enrichment and oxygen-depletion affect both the deep central basins and a number of coastal areas, even though strategies for nutrient reduction have lately been implemented. In order to better understand why those threats are expanding and formulate more effective remediation strategies two main achievements are needed: (1) new data on benthic nutrient dy...

This research focused on features of a genetically isolated population of cutthroat trout (Oncorhynchus clarki) in the Triangle Lake basin of coastal Oregon. A falls at the outlet of Triangle Lake has blocked upstream migration of trout and anadromous salmonids into the basin. Cutthroat trout were found throughout the six study streams of the Triangle Lake basin in association with other native fishes and introduced warmwater fishes. Warmwater species (e.g. Centrarchidae) were restricted largely...

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 environmental conditions in which they exist. Here I examined the impacts of storm-induced saltwater intrusion and post-intrusion conditions on the structure and growth of an oligohaline wetland plant comm...

Pelagic ecosystems are inherently complex in coastal inlets where they are controlled by physical processes and influenced by biogeochemical and foodweb interactions. Meteorological events are important drivers of this ecological variability. This thesis investigates their effect on the plankton dynamics of Lunenburg Bay, an inlet on the Atlantic coast of Nova Scotia (Canada). In this region, meteorological events are dominated by upwelling in summer, which are a dominant source of flushing and ...

Coastal communities in Ecuador – and worldwide – are vulnerable to climate change due to both marine and inland pressures. Studies predict that climatic changes will impact strongly on coastal zones, with particularly negative effects on communities that rely on mangrove ecosystems for their livelihoods. Unfortunately, relatively few studies have determined how these communities perceive climate change and other environmental changes witnessed during their lifetime. This research gathered primar...

Much research has been devoted to understanding the ocean carbon cycle because of its prominent role in controlling global climate. Coastal oceans remain a source of uncertainty in global ocean carbon budgets due to their individual characteristics and their high spatial and temporal variability. Recent attempts to establish general patterns suggest that temperate and high-latitude coastal oceans act as sinks for atmospheric carbon dioxide (CO2). In this thesis, carbon cycling in two Canadian co...

This research challenged popular assumptions that Canadian coastal environments remain relatively un-impacted by human activities, and that current practices in coastal management are sufficient to ensure sustainability of coastal resources and communities. Using a systematic analysis of the literature, the performance of integrated coastal management, as reported for other nations, was examined, and shared impediments to progress were identified. Drawing from these insights, it was determined...

Outcrop studies of Eocene-Oligocene depositional sequences exposed in the Coastal Plain of Alabama and Mississippi disagree on the sea level history recorded across several stratigraphic intervals. The placement of depositional sequence boundaries (unconformities caused by sea level fall) and maximum flooding surfaces relative to the lithostratigraphy by various authors implies that relative sea level change was diachronous across the central Gulf Coast. In addition, the number of depositional s...

Present coastal systems along the east Texas coast evolved during the past 3.5 ky of relative sea-level stillstand following a rapid sea-level rise 4 ka. Closure of proto-Galveston Bay, caused by spit accretion of Galveston Island and Bolivar Peninsula, formed Bolivar Roads approximately 3.3 ka. Increased tidal prism and entrenchment over the Trinity River incised valley led to inlet stabilization and intensification of tidal influence. The present shoreface and inner shelf package is characteri...

Research Doctorate - Doctor of Philosophy (PhD) / The Hunter Estuary Wetlands (NSW, Australia) are important locally, nationally and internationally. They contain significant breeding and nursery grounds for commercial fisheries and are essential shorebird foraging and roost sites. Originally a mosaic of fresh- and salt-marsh, these wetlands have become degraded due to the erection of flood mitigation structures. Reintroduction of a more natural tidal regime is proposed, which is expected to dec...
