Emission of biogenic halocarbons in temperate and tropical coastal zones
… transport processes. We identified that strong coastal sources do exist in this region, but that their distribution is patchy and model studies should not assume a constant, strong coastal source. Laboratory and field measurements were combined in a final discussion providing annual emission …

Microplastic adherence to common species of macroalgae found throughout Scottish coastal zones
… of macroalgae found throughout the Scottish coastal zone. A baseline time series data set was created to assess the microplastics found within water samples in addition to sampled Fucus vesiculosus fronds. Additionally, a positive control experiment was created to assess if microplastics …

Framework for multi-vehicle adaptive sampling of jets and plumes in coastal zones
This thesis presents a framework for the sampling of thermal and effluent jets and plumes using multiple autonomous surface vehicles. The framework was developed with the goal of achieving rapid and accurate in-situ measurement and characterization of these features. The framework is presented as a …

Analysis of spanish coastal tourism on the national, regional and local levels
Coastal tourism is a fast-growing economic driver worldwide. Spain is a bright example of a coastal country with a leading position in the global tourism market, especially with the ‘sun and sea’ product. Tourism plays a vital importance for Spain because it represents 14.2% of GDP (Gross Domestic …

Making decentralized coastal zone management work in Indonesia: Case studies of Kabupaten Konawe and Kabupaten Pangkajene Dan Kepulauan
Coastal governance in Indonesia is entering a new phase with new administration mechanisms, following the changes of political, administrative and fiscal framework resulting from decentralisation policy. For the first time provincial and district governments have mandates, resources, and …

The U.S. Coast Guard sector construct : A study of organizational culture
… responsible for maritime security in port and coastal zones into a new organization called the Sector construct. This thesis examines the cultural issues associated with this reorganization and poses three questions: 1. What are the cultural challenges associated with the Sector organization? …

Evaluation of spatial fragmentation of protected areas using the Spatial Assessment for Coastal Protected Areas in Caribbean Small Island Developing States
… where populations are regulated to living in coastal zones due the geographic size of the islands. The disaster risk implications to communities in coastal zones is greater due to the climate change consequences of sea level rise along with the increase frequency and intensity of storms. …

Earth Observation Data-Driven Assessment of Local to Regional, Contemporary, and Emerging Coastal Environmental Security Challenges
Coastal zones are hotspots of global environmental changes. Worldwide, coastal environments face multiple, interactive stressors caused by both natural and anthropogenic impacts on climatic, oceanographic, ecological, and socio-economic processes such as sea level rise, storm surges, hurricanes, …

Beyond the evacuation zone: Japanese evacuation and resettlement in Spokane, Washington
… populations. Located outside the prohibited coastal zones in eastern Washington, Spokane's Japanese community of approximately 300 was not evacuated or interned. However, Spokane played an important role as a "safe" zone or "straddle" area for evacuees and resettlers seeking refuge from …

Spectral characterization of desert surfaces in Kuwait by satellite data
… assessment of the Gulf War on the desert and the coastal zones of Kuwait. Due to the appearance of many new surface features, a study was necessary to characterize their spectral signatures as detected by Landsat Thematic Mapper (TM) data. A sophisticated image analysis was applied to the Landsat …

Interactions between currents and the spatial structure of aquatic vegetation
… channels and rivers, as well as in lakes and coastal zones. This vegetation grows in a wide range of flow environments as well, from stagnant water to highly turbulent flows dominated by waves and currents. Feedbacks between the dominant currents and the vegetation not only significantly alter …

Hydrogeo-Eco-Systems in Aquaba/Jordan - Coasts and Region
… fresh water/seawater interface in the coastal zones was investigated by applying vertical geoelectric surveys and models of several methods to confirm its coincidence with the aquifer’s flow amounts, where human impacts in terms of over-pumping allowed more encroachment of seawater into …

Modeling Liquefaction-Induced Road Disruptions in Cascadia Megathrust Earthquakes: Implications for Emergency Response and Access in the U.S. Pacific Northwest
… show that impacts are concentrated in low-lying coastal zones, river valleys, and urban waterfronts, with major disruptions expected along critical routes including U.S. Route 101. Local mobility is further examined in Pacific and Grays Harbor Counties, Washington, where limited network …

The Influence of Changing Nutrients and Warming on Phytoplankton and its Interactions with Zooplankton in the North Sea
Coastal zones are increasingly stressed by human activities and climate change. In the German Bight (North Sea), nitrogen (N) and phosphorus (P) inputs have declined markedly while sea-surface temperature (SST) has risen. This thesis examines how these changes affect phytoplankton (Chlorophyll-a, …

The derivation of fire hazard indices and burning prescriptions from climatic and ecological features of the fynbos biome
… stations to define five distinct fire climate zones within the fynbos biome. The seasonal cycle of fire danger is pronounced in two inland zones, but mean fire danger shows little seasonal fluctuation in three coastal zones. Fires will occur in the coastal zones under occasional suitable …

Improving the spatio-temporal characterisation of South Africa's dynamic coastal zone using hyper-temporal satellite imagery
Coastal zones, the interface between the marine and terrestrial realms, are highly productive regions that deliver critical goods and services, while facing many pressures from urbanisation, industrial development, overexploitation, pollution and climate change. Their effective management is …

Numerical Model Simulation of Offshore Flow During the Winter Season
… variability of heat and moisture flux in coastal zones, adequate descriptive models of mesoscale coastal circulation and weather patterns demand high spatial resolution in the analysis of wind, temperature and moisture patterns. To obtain realistic concepts of offshore flow the sparse …
