Deformation features within Plio-Pleistocene Bredasdorp Group coastal aeolianites within the Southern Cape, South Africa, have been studied to resolve the neotectonic history of the region, estimate the recent to current upper-crustal stress field, and infer seismic hazard. Previous studies indicate possible Quaternary faulting within the Southern Cape, major faults within the underlying geology, and a horizontal maximum compressive stress (SHmax) orientated WNWESE to NW-SE. This study utilised ...

<p> Coastal systems are facing many challenges including climate change, sea-level rise, storm surge, and erosion, all of which contribute to land loss. In Louisiana, this has led to the development of a coastal Master Plan supported by habitat suitability index (HSI) models to predict wildlife responses under various management scenarios. However, these models were not originally intended for this purpose and their functionality at large spatial scales is unclear. My goal was to use maximum ent...

Includes bibliographical references. / In recent decades an emphasis on understanding the long-term variability of ecosystems and their responses to environmental changes has been undertaken. This has mainly been achieved through the identification and analysis of fossil material in lake sediments. In the South Africa, the relative paucity of available sites and the semi-arid nature of the region have led to incomplete or discontinuous palaeoclimatic records. However, lakes along the southern Ca...

Through an analysis of three rural communities in these provinces, this research sought to understand how and why benefits arising from the use of coastal resources in the fisheries and mining sectors are shared and distributed in the manner that they are.

Kirkby, Kenneth

As coastal development pressures continue to transform coastal regions into private havens for the benefit of a privileged few, conflicts over coastal access issues continue to increase. The southern Cape coast of South Africa is no exception to this phenomenon and the privatization of this coastal region is taking place at a rapid rate. Associated with this trend is the notable increase in large-scale golf estates developed along this coastline. Due to their size, their close proximity to the c...

Wastewater disposal often has deleterious impacts on the receiving environment. Low levels of dissolved oxygen are of particular concern. Here I investigate the impacts on dissolved oxygen and carbon chemistry of screened municipal wastewater in the marine waters off Victoria, B.C., Canada. I analyzed data from a series of undersea moorings, ship-based monitoring, and underwater remotely-operated vehicle video. I used these observations to construct a two-layer box model of the nearfield receivi...

Coastal marshes can have high rates of carbon (C) accumulation associated with high primary productivity and sedimentation rates, and low rates of microbial decomposition. Mitigation for the loss of saline marshes by restoration and creation is becoming widespread; however, a greater understanding of the timescale and capacity for these new sites to function as C sinks is needed. For this study, we examined a chronosequence of six created coastal marshes ranging from 0 to 32 years old and two ad...

<p> Thermokarst lakes are a dominant factor of landscape scale processes and permafrost dynamics in the otherwise continuous permafrost region of the Arctic Coastal Plain (ACP) of northern Alaska. Lakes cover greater than 20% of the landscape on the ACP and drained lake basins cover an additional 50 to 60% of the landscape. The formation, expansion, drainage, and reformation of thermokarst lakes has been described by some researchers as part of a natural cycle, the thaw lake cycle, that has rewo...

Land-based observations may contribute to an overall understanding of behaviour of large marine vertebrates and may help us understand how these animals react to climate change. I observed marine megafauna (cetaceans, Basking shark, and Sunfish) from Cape Clear Island situated in the south-west of Ireland. The study took place during the summer months (June - August 2008) because the majority of Leatherback turtles, Sunfish and other megafauna species are sighted in Irish waters in this period. ...

Olivier, Pieter Ignatius

Habitat loss and fragmentation drives the current extinction crisis. The processes through which it affects biodiversity, however, are complex and poorly understood. This is especially true for spatially complex regions that comprise a mosaic of land-use types, which often range from protected areas to dense human settlements. In such human-modified landscapes, it is important to determine the extent and impact of changing land-use patterns on biodiversity if we are to meet conservation targets ...

Alling, Vanja

Arctic rivers transport 31-42 Tg organic carbon (OC) each year to the Arctic Ocean, which is equal to 10% of the global riverine OC discharge. Since the Arctic Ocean only holds approximately 1% of the global ocean volume, the influence of terrestrially derived organic carbon (OCter) in the Arctic Ocean is relatively high. Despite the global importance of this region the behavior of the, by far largest fraction of the OCter, the dissolved organic carbon (DOC) in Arctic and sub-arctic estuaries is...

Gilbert, Matthew Edmund

When considering the large amount of work done on dune ecology, and that a number of the classical ecological theories originate from work on dunes, it is apparent that there remains a need for physiological and mechanistic explanations of dune plant phenomena. This thesis demonstrated that in the extreme coastal environment dune plants must survive both high rates of burial (disturbance), and low nutrient availability (stress). The ability of four species to respond to these two factors corresp...

A detailed feeding study of eleven inshore top predatory teleosts in the eastern Cape is presented. Material collected largely from line-caught fish was augmented by spearfishing. The predators were grouped according to habitat: pelagic, soft-sediment demersal and reef species. Pelagic fish examined were Lichia amia, Pomatomus saltatrix, Seriola lalandi, Atractoscion aequidens, Katsuwonus pelamis and Thunnus albacares. Stomach content analyses revealed that their prey varied according to size an...

A line of pumping wells, 100-175 m from the shore in a shallow coastal aquifer east of Puerto Petasco, Sonora, Mexico, supplied salt water at a rate of 7,500 to 11,500 m³/day to a shrimp aquaculture facility. This water exhibited salinities as high as 41.5 parts per thousand (ppt) and the well farthest inland yielded the most saline water. Effluent was discharged from the facility at an average rate of 6,000 m³/day to two lakes 400 m inland from the wells. In 1979, the salinity in the first lake...

The development of an open pit phosphate mine in 1965 near Aurora, North Carolina, required groundwater withdrawals in excess of 50 million gallons per day for pressure relief from the underlying confined Castle Hayne aquifer. The effects of pumping from this limestone aquifer were widespread, extending over an area of more than 2,000 square miles in the first year before the pressure cone reached a stabilized condition. Salt water encroachment by lateral movement from downdip in the aquifer and...

Master's Report / Initially attributed to natural formation processes, shellmounds were eventually acknowledged as cultural products. They were presumed to be the remains of prehistoric hunter-gatherer subsistence practices and of no great antiquity. Scholarly analysis of shellmounds focused on human consumption and discard accumulation rates aimed at establishing population estimates and the antiquity of the mounds. The identified strata were considered to represent insignificant cultural chan...

Building on research conducted over the last ten years, this dissertation explores how local understandings and manifestations of gender violence are changing as women and men learn about human rights and gain access to state-based forms of justice. Wife abuse in coastal Ecuador is often explained as a result of machismo and an enduring culture of violence. I challenge this conception by demonstrating how political, economic and social processes normalize gender violence, and by showing how tran...

The limited range of garrick/leervis Lichia amia, its popularity as a gamefish to all sectors of the marine recreational linefishery and the degradation of many estuaries which function as nurseries for this species, has aroused concern about the stock status of this species. In addition, other than a preliminary investigation conducted by ORI in 1992, relatively little research has been undertaken on this important recreational species. Considering the recreational value of L. amia and the need...

Storm water runoff is a leading cause of degradation in the water quality of receiving water bodies. Although legislation requires that Environmental Impact Assessments (EIA) are performed and Environmental Management Plans (EMP) put in place for the construction of high density housing developments, there is generally very little evidence that real measures are developed to monitor and actually assess the extent of the impact that construction activities have on the environment during the ...

Climate change and warming have been linked to enhanced coastal erosion in the arctic. Specifically, permafrost is believed to be thawing at greater rates, and wave dynamics are expected to increase in intensity. As a result, thermokarst activity, which includes the occurrence of retrogressive thaw slumps, will be more frequent along arctic coasts. / The availability of airborne and spaceborne imagery in the arctic over the last fifty years has made possible the temporal analysis of permaf...
