During the last two decades the scientific community has recognised the importance of the tropical Atlantic Ocean and the upwelling regions on the Earth's climate. This recognition has opened new questions such as: ¿What are the mechanisms for the ocean to adjust to variations in atmospheric forcing?, ¿Is there any indirect relation between the atmospheric seasonal cycle and the response of the surface ocean?, ¿How are the meridional boundary flows connected with the zonal jets in the interior o...

This thesis examines the effects of coastal protection structures upon the sandy coastline of Rarotonga, Cook Islands. The coastline is surrounded by a fringing coral reef which is continuous except for six passages. Water from the open sea enters the lagoonal area by waves breaking over the roof and propagates towards the shore as reformed waves. A detailed analysis of beach change and adjustments in front of and adjacent to coastal protection structures is presented. While there has been a sub...

The phytoplankton community dynamics and the processes influencing phytoplankton community structure were investigated in Beatrix Bay, Pelorus Sound, New Zealand. The particular focus was on bottom-up resource acquisition driving phytoplankton dynamics in this coastal ecosystem. Sampling for water column structure, nutrient concentration, and phytoplankton community composition was done over two years in conjunction with experiments that manipulated nutrient concentration and light levels, to te...

<p>Evolution of rocky coastlines is controlled by littoral, biological and fluvial processes. Resultant landforms are overprinted and/or new ones formed as a result of changes in sea level caused by glacioeustasy and/or local tectonics. On carbonate coasts, chemical erosion in the form of karstification takes on a dominant role. Type of karstification is an important factor in understanding carbonate coast evolution and landform development so it is critical to identify type of karstification. I...

<p> Despite reductions in species diversity, few studies in wetlands investigate the relationship between biodiversity and ecosystem function (BEF). My research explores the BEF relationship in a recently restored salt marsh in Long Beach, California. I hypothesized that: (1) increasing plant diversity would result in higher primary productivity and decreased recruitment of native salt marsh plants, (2) observed variation in responses would be correlated with species-specific variation in ind...

Tsunamis and hurricane induced waves are responsible for many coastal bridge failures, especially in the last decade. In the current study, three countermeasures (reducing the entrapped air, elevating the structures and rigidifying the structures) are considered, two wave types (solitary wave theory and Stokes wave theory) are chosen, and two bridge types (single bridge deck and twin bridge decks) are taken into account. Parametric studies are conducted based on Computational Fluid Dynamics (CFD...

This thesis has investigated the improvement of forecasting temperature in a coastal embayment through the assimilation of sea surface temperature (SST) observations. The research was prompted by the increasing pressures on the coastal marine environment. To better manage the environment, an improved understanding of its future state is necessary. Improving the forecasting of temperature advances our knowledge in this direction. Whilst assimilation of SST is routinely carried out for oceans, its...

Coastal areas are very susceptible to contamination due to the interaction of marine and anthropogenic processes. Persistent Organic Pollutants (POPs) are organic compounds very resistent to photolysis and chemical and biological degradation. According to its physicochemical characteristics, POPs are worldwide distributed. These contaminants tend to bioaccumulate through the food webs, so that predators are more sensitive to this contamination. Seabirds are highly exposed to organic pollutants d...

Liquid waste discharged from industrial outfalls is categorized into two major classes based on their density. One type is the effluent that has a higher density than that of the ambient water body. In this case, the discharged effluent has a tendency to sink as a negatively buoyant jet. The second type is the effluent that has a lower density than that of the ambient water body and is hence defined as a (positively) buoyant jet that causes the effluent to rise. Negatively/Positively buoyant jet...

Coastal erosion, population decline, and economic deterioration, in the rural coastal community of Sydney Mines, Cape Breton, are concerns upon which the provincial government is focused. This thesis explores how ideas of permanence, adaptation, and sacrifice can engage the prevailing erosion of both the coastline and community, in terms of the physical cliff face, population, and economy. Articulating methods of responding to the various conditions of erosion enables an evolving and didactic ar...

Franzitta, Giulio <1980>

Since large stretches of European coasts are already retreating and projected scenarios are worsening, many artificial structures, such as breakwaters and seawalls, are built as tool against coastal erosion. However artificial structures produce widespread changes that alter the coastal zones and affect the biological communities. My doctoral thesis analyses the consequences of different options for coastal protection, namely hard engineering ‘artificial defences’ (i.e. impact of human-made stru...

Ianson, Debby C.

An improved understanding of oceanic biogeochemical cycles is critical for predicting global climate. In coastal upwelling regions fluxes of both carbon and nitrogen are disproportionately large relative to the global ocean. This is especially true of the downward flux of organic matter that transports carbon away from the ocean surface layer causing absorption of atmospheric carbon dioxide (i.e. the 'biological pump'). In addition to biologically limiting nutrients, upwelling brings inorganic c...

The connection between education and migration from rural areas is one that has been made since Western democracies began keeping statistics. While there has been considerable work done on the migration experiences of rural Canadians, there has been little research done on how the educational experience of rural people actually figures in migration decisions and experience. Education is typically understood as a modernising and a disembedding force facilitating the transition of societies and in...

Wave breaking is an important coastal process, influencing hydro-morphodynamic processes such as turbulence generation and wave energy dissipation, run-up on the beach and overtopping of coastal defence structures. During breaking, waves are complex mixtures of air and water (“white water”) whose properties affect velocity and pressure fields in the vicinity of the free surface and, depending on the breaker characteristics, different mechanisms for air entrainment are usually observed. Several...

There has been little research examining littoral productivity in freshwater ecosystems. Previous studies have focused on pelagic production, largely because pelagic production was viewed to be the predominant source of carbon in aquatic ecosystems. More recently there has been some research to suggest that the productive capacity of littoral zones may be significant, especially in nutrient-poor ecosystems, where the transfer of carbon through the food chain is driven by microbial activity ...

This study examines sediment storage and transfers in gullies of coastal British Columbia, and how logging affects sediment storage and transfers. Both fluvial and debris flow transport of sediment occur in gullies, and the amount of fluvial transport of sediment which occurs will affect the magnitude of a subsequent debris flow. Coarse woody debris (CWD) may affect the storage and transfer of sediment in the gully channel, and logging can affect the supply and type of CWD. To determine whether ...

The influence of salal on tree growth has attained considerable attention in coastal British Columbia. Field observations, surveys, and studies in the CWH zone have indicated poor growth performance of crop tree species in salal-dominated plantations and natural immature and old-growth stands. Where sites have been burned and planted, tree growth has improved; similar effects have been observed for naturally regenerated stands. Immature stands that developed after wind disturbance or harvesting ...

Vegetation science, like any science, uses classification to organize knowledge about plants and plant communities. Classification is helpful for understanding how different plant communities relate to one another and their environments, for facilitating further studies of vegetation, and for conservation. To familiarize onself with vegetation of a large area, it is very convenient and efficient to begin with a few general units, such as plant orders rather than with many very detailed units, su...

Response to fertilization is a function of the degree to which nutrients are limiting growth, the capacity of individual trees to respond to nutrient inputs, the degree to which other factors limit growth, and the possible extrinsic effects of treatment (e.g., root mortality due to fertilizer-induced soil pH effects). Recognition and examination of these factors is essential if response to fertilization is to be predictable. Over the past 25 years numerous western hemlock fertilizer trials have ...

Louisianas saltmarshes, one of the most productive wetlands in the nation, are undergoing severe erosion due to hydrodynamic forces (storm surge) and sea level rise. The erosional behavior of coastal saltmarshes, which possess cohesive sediments as their integral components, are very difficult to analyze and understand. The erosional resistance of cohesive sediments determines the stability and sustainability of coastal wetlands. This erosional resistance is expressed as an erosion threshold or ...

A study of the chaetognath population in the waters of western Canada was undertaken to discover what species were present and to determine their distribution. The plankton samples examined were collected by the Institute of Oceanography of the University of British Columbia in the summers of 1953 and 1954 from eleven representative areas along the entire coastline of western Canada. It was hoped that the distribution study would correlate with fundamental oceanographic data, and that the presen...

Coastal land loss in Louisiana is occurring at astounding rates. New technologies for shoreline protection are needed that incorporate traditional engineering designs with natural systems (e.g., oyster reefs). Under optimal environmental conditions eastern Oysters (Crassotrea virginica) can biologically dominate artificial concrete reef structures used as coastal breakwaters within the intertidal zone. These reefs can also serve as oyster broodstock sanctuaries providing a nexus to the public oy...

The data recorded between March 3, 1969, and October 31, 1969, by a wind gauge installed at the South Jetty, Newport, Oregon, were analyzed. The components of each observation were treated as if they were an independent, normal, bivariate distribution and standard statistical procedures were applied. It was found that the wind gauge is obscured by the land to the southeast and that the adjacent land has the effect of channeling the wind so that it comes from the north, the east, and the south.

This thesis examines coastal form and sediments of the Marlborough Sounds, New Zealand. An important aspect of coastal behaviour in this landscape stems from linkages between catchment and coast. Focus is therefore placed on the manner in which sediment delivered from catchment sources is redistributed within the shore and offshore domains. Coastal response is shown to depend on two factors: the form of the receiving sites and the mobility of sediments within them. Investigation of coastal landf...

The main goal of this thesis is to investigate the formation of nocturnal coastal fronts (hereafter CF) in the Mediterranean basin producing nocturnal offshore precipitation near the coastline. After sunset the cooled inland air moves to the coastline driven by drainage winds as a density current. When this air encounters the warm and wet sea-air a CF is formed. Therefore the warm air mass is lifted and when ascending clouds may form producing in some cases precipitation. The influence of the la...
