Following the Deepwater Horizon oil spill in April, 2010, hard structures were constructed to deter oil migration into sensitive marsh areas behind Fourchon Beach, LA These hard structures created conditions for accumulation and burial of oil across an 8 foot deep beach vertical profile. Buried oil persists in these areas due to anaerobic conditions of beach groundwater. The objectives of this thesis are to compare the rate and extent of biodegradation of 3-ring PAHs in crude oil deposits from t...

Airports contribute about 5% of the gross domestic product and employ over 7 million people in the United States. The purpose of this qualitative multiple-case study was to explore the strategies that airport managers need to increase nonaeronautical revenue. A generic strategy does not exist to assist airport operators in generating operating income. Aeronautical revenue does not always provide sufficient funding for airport operations and existing research does not consistently provide effecti...

<p> As sea levels rise, management strategies are needed to protect coastal wetlands from increased inundation. Sediment augmentation is a strategy in which a layer of sediment is sprayed across the marsh to raise the marsh's elevation and reduce inundation. This study looks at the short-term impact of sediment augmentation on vegetation and invertebrate communities. Abiotic measurements, invertebrate cores, and plant parameters were analyzed before and after augmentation in a before-after-contr...

Conventional knowledge of fynbos fire ecology is based on the summer-autumn fire regimes of the western Cape Floral Kingdom (CFK) where the climate is Mediterranean. However, the climate in the eastern coastal-CFK is milder and rainfall occurs year-round, with presumed effects on fire regimes. The Garden Route National Park (GRNP) has recently been established in the region, in a landscape where indigenous forests, fire-prone fynbos shrublands and fire-sensitive plantations of invasive alien tre...

Short period ( <1 hour ) oscillations are often seen superimposed on tidal curves at Port Renfrew, B.C. In order to determine the nature of these oscillations, time-series of sea-level variation were obtained in Port San Juan; their analysis revealed energy peaks at periods of 34.7 min. and 13.5 min. A theoretical model of wave excitation of a basin of variable depth fitted to Port San Juan by edge waves travelling on the shelf accounts reasonably for the observed frequencies. Bottom friction wa...

Rain-on-snow, in which rainfall occurs upon a previously existing snowpack, complicates runoff response to rain events. In some situations the snowpack absorbs rainfall; in others, runoff is enhanced by significant snowmelt. Rain-on-snow has generated major floods around the world, particularly in coastal, mountainous regions such as southwestern British Columbia, where the rugged topography can cause rapid and varying transitions between rainfall and snowfall within the same watershed, and warm...

RNA viruses are major pathogens o f animals and plants and include viruses that are of enormous economic and public-health concern. In the ocean, RNA viruses infect organisms from bacteria to whales, but RNA virus communities in the sea remain essentially unknown. Although what we know of marine RNA viruses is restricted to a limited number of isolates, emerging data suggest that RNA viruses might be more abundant, and are more ecologically important, than has been suggested. Therefore the ...

This research was designed to assess the response of the flora of forested sites to the methods employed by B.C. Hydro and Power Authority for the initial clearing of transmission line rights-of-way in coastal British Columbia. Seven immature forest vegetation units adjacent to, and seven early seral vegetation units on, the transmission line rights-of-way were identified. The environmental parameter most highly correlated with both the immature forest and early seral vegetation units was slope...

Field measurement and numerical modeling are the most popular and fundamental approaches for studying mixing pattern in rivers and coastal waters. Due to the limitations associated with both of these methods they should be used together to verify each other. Extensive field measurement was conducted on the effluent plume from the outfall of the Capital Region waste water treatment plant in the North Saskatchewan River. Tracer was injected at the outfall location and the mixing pattern was inv...

The transition from old-growth to second-growth British Columbia coastal Douglas-fir has resulted in reduction of log size and increased proportion of juvenile (core or crown-formed) wood. Determination of the zone of transition from juvenile to mature wood is critical to the definition of wood quality and timber value. Thirteen unpruned, two pruned second-growth, and two unpruned plantation-grown coastal Douglas-fir trees were sampled to analyze the hypothesis that the transition in relative d...

This is a study of the hydrologic behavior of a forested west coast mountain slope soil. Flow mechanisms were investigated using experimental results, mainly outflow hydrographs, and a simple model of saturated flow over a steep bed, described in the second chapter and called the kinematic wave model. The main experiments consisted of subjecting the forest plot to both concentrated and uniform irrigation. The rationale for using concentrated irrigation was that it was expected it would enhance...

Rain-on-snow has been recognized as an event with potential for increasing flood and debris torrent hazards. However the effects of deforestation on increasing this hazard are not well understood. To better understand this phenomena a study was conducted in the Jamieson Creek experimental watershed near Vancouver B.C. Its primary objective was to determine the effects of forest harvesting on snow melt rates and subsequent runoff during rain-on-snow events. The energy balance of a snowcover and ...

Lichenological studies in western North America have lagged behind those of eastern North America and Europe. Several manuals, now mainly outdated, are available for the western United States; no descriptions or keys have ever been compiled for the British Columbia lichen flora. This flora of the Coastal Douglas-fir Dry Subzone in British Columbia, Canada, partially fills this void. The Coastal Douglas-fir Dry Subzone is a small area in the southwestern portion of the province composed of a na...

The rate of dispersion of atmospheric pollutants and the volume of atmosphere available for the dilution of pollutants are examined in an unstable suburban atmosphere at a coastal location. Within the framework of the statistical theory of diffusion, it can be shown that the non-dimensional dispersion functions σ[ sub y]/σ [sub v]t and σ[ sub z]/σ [sub w]t can be determined by integration of the Eulerian spectral functions multiplied by appropriately scaled sampling functions. This scaling, whic...

The coastal zone is one of British Columbia's most outstanding yet little studied attributes. The importance of recreation in British Columbia's coastal zone has been increasing dramatically in recent years while other land and water uses are also concentrated in this zone. As a result, resource use conflicts are becoming more frequent and there is an expressed need for suitability and capability information for the coastal zone. The purpose of this thesis is to develop a coastal zone classific...

Cornwall, Ira Hugh Brooke

The Port of Vancouver, situated on Burrard Inlet in southwestern British Columbia, is of major importance both as a world deep-sea port and as a coastal port. This importance in a dual function results from: first, the wealth of forestry and fishery resources of coastal British Columbia; secondly, the ability of the port to forward to world markets the produce resulting from these resources; and finally, the fact that Vancouver is a major hulk grain exporting port. The port occupies all of Burr...

The coastal zone consists of a narrow resource complex occurring at the interface between the sea and land. It not only serves as a transition zone between the marine and terrestrial environments but is also a unique environment possessing qualities which emerge from the dynamic relationship between land and sea. Man has, throughout history, found the resources of this area to be highly desirable for a multiplicity of uses. Now, however, segments of society are expressing considerable dissatisf...

Certain criteria used to distinguish chytrid taxa are highly variable and unstable. This variability is evident from a study of ten single-spore isolates of an Entophlyctis species collected in Western Canada, Oregon, California and Nevada. The observed variations place these Entophlyctis isolates in different species, genera, subfamilies, families, and series, thus demonstrating that various current taxonomic dispositions and concepts are of questionable value. Zoosporic fungi, mainly Chytridi...

Increasing demands for the natural resources of British Columbia coastal forests have led to conflicts between resource users. In addition recent demand for intangible "non-economic" resources, such as outdoor recreation is creating added pressure upon the wildland resource base. The British Columbia Forest Service, although restricted to some extent by a narrowly-worded "wood production" statute, has attempted to resolve forest resource conflicts by administrative action such as the developmen...

The impacts of climate change are disproportionally felt across the planet, with small island developing states some of the countries most at risk. Furthermore, climate change may compound existing problems such as over harvested resources, leading to knock-on effects on national economies. Both direct and indirect stressors may impact communities differently based on their level of exposure to stressors, their intrinsic sensitivity to these stressors, and their ability to adapt to stressors.

<p> The development of offshore wind energy is moving forward as one of several options for carbon-free energy generation along the populous US east coast. Accurate assessments of the wind resource are essential and can significantly lower financing costs that have been a barrier to development. Wind resource assessment in the Mid-Atlantic region is challenging since there are no long-term measurements of winds across the rotor span. Features of the coastal and inland terrain, such as such as th...

Abstract This study is a re-analysis of the material from the wetland settlement of Sārnate, excavated between 1938 and 1959 by Eduards Šturms and Lūcija Vankina. The site, dated to the Neolithic of the East Baltic, is located on a former lakeshore in the littoral belt of the Kurzeme Peninsula, western Latvia. First, the many separate dwelling assemblages of material were arranged into three major groups on the basis of their pottery: dwellings with Comb Ware (undated), dwellings with Early Sā...

South African dune fields are severely threatened by human expansion and in the long run the stabilisation of many dunes will be necessary. The alien grass Ammophila arenaria is the most important drift sand stabiliser at present in South Africa. Although not invasive, the current impact of A. arenaria on the dune systems of South Africa is considerable, and thus the stabilising benefit of the grass seemed to may be outweighed by its negative consequences. It is therefore preferable to use indig...

Arbuscular mycorrhizas (AM) are mutually beneficial symbiotic associations between the roots of plants and certain Zygomycetous fungi. The role of AM fungi in coastal sand dunes has been explored in many parts of the world, though little work has been conducted in South African dune systems. This study aimed to investigate the presence and extent of mycorrhizal colonisation of a coastal sand dune in South Africa. The roots of five plant species (Scaevola plumieri, Arctotheca populifolia, Ipomoea...

A multi-scale asymptotic theory is derived for the evolution and interaction of currents and surface gravity waves in water of finite depth, under conditions typical of coastal shelf waters outside the surf zone. The theory provides a practical and useful model with which wave-current coupling may be explored without the necessity of resolving features of the flow on space and time scales of the primary gravity-wave oscillations. The essential nature of the dynamical interaction is currents modu...

Coastal zone definitions are typically guided by the presence of absolute demarcations. As a result, the coastal zone becomes confined to, and identified as, an absolute space. This research challenges the ‘fixed’ nature of the coastal zone and suggests that there are a wide range of relational spaces that overlap and engage with each other to form the coastal space. These spaces and their sphere of influence extend beyond the ‘boundaries’ of what is legally defined as the coastal zone. Multiple...
