The shallow waters west of Scotland feature strong variability in water properties on a variety of temporal scales. While the region is known to be subject to both coastal and oceanic influences, the causes of variability are poorly understood. The limited characterisation of changes in coastal waters impacts our ability to explain the behaviour of coastal ecosystems, and predict their resilience to future climate scenarios. This thesis uses historical data in conjunction with recent cruises and a coastal mooring to investigate the causes of variability in the waters west of Scotland. Two new inter-annual salinity time series on the European shelf are developed. The spatial variability in salinity in shallow waters is greatest during winter and increases by a factor of four between the shelf edge and the coastline. At the shelf edge, new observations of the along-slope current suggest that it is stronger but less stable during winter, leading to a greater availability of oceanic water on the outer Malin Shelf. However unlike other documented shelf regions, shelf edge processes do not directly influence Scottish coastal water properties. A baroclinic current originating in the Irish Sea is the main influence near the Scottish coast during quiescent periods, but wind forcing dominates shelf processes during most winters, with prevailing winds tending to drive oceanic water towards the coast. While salinity in the Sea of the Hebrides is moderately correlated to wind, coastal salinity is sensitive to both advective processes and freshwater runoff. On inter-annual time-scales, salinity on the Malin Shelf is higher when the North Atlantic Oscillation (NAO) is positive, whereas the northern Irish Sea is fresher during a positive NAO state. Salinity and flow pathways in Scottish coastal waters appear to be resilient both to changes in the Rockall Trough and a warming climate on decadal time-scales.

For Maori, the management fo New Zealand�s coast and its resources is fundamental to their cultural identity. Iwi and hapu throughout New Zealand have close relationships with the coast and unique rights and responsibilities for its future management. However, there does not appear to be wide recognition of the crucial role of Maori in New Zealand�s coastal management regime. Co-management initiatives in coastal management, particularly under the Conservation Act 1987, Resource Management Act 1991 and several legislative initiatives controlling fisheries management, are explored and critiqued. Overall, the initiatives demonstrate that progress is being made in coastal management for better protection of Maori coastal values. Nevertheless, there is scope for further improvements concerning greater Maori involvement in coastal management. Recommendations for genuine co-management systems in New Zealand�s coastal management regime include effective communication between iwi and Government; appreciation of the unique nature of each iwi in New Zealand; involvement of a third party communicating between iwi and Government representatives; appropriate funding and resources to maintain the co-management system, and encouragement and motivation from the Government to initiate and maintain the co-management system.

ABSTRACT Coast zones are ecology sensitive areas, coastal wetlands may provide many biological, chemical and physical functions. However, as a result of economy develops, it makes many industrial estate and large-scale reclamation along the coast, the coastal wetlands are facing critical threatens, includes of habitat loss, industrial wastewater, wetlands degradation , fishery reduction and coastal zones erosion. In order to achieve the sustainable use of coastal resources and pure industrial wastewater and provide wildlife habitat, creating or restoring wetlands may resolve many problems in Taiwan¡¦s coastal zones. Coastal wetlands restoration, enhancement, and creation can clear up wastewater, increase wetlands and slow environmental destruction. Coastal wetlands also achieve recreational, educational , cultural functions, environmental education, and sustainable development of Taiwan¡¦s coastal zones. This thesis collect constructed wetlands history, and application cases, aim at the sensitive coastal in Taiwan to suggest constructed wetlands strategies.

This study investigates the distributions of trace metals and their controlling mechanisms in the Kaoping coastal zone. Concentrations of most dissolved metals were generally lower in the wet season than in the dry season in the Kaoping Estuary, showing clearly the effects of river discharge rate and water residence time on metal distributions. Dissolved trace metals (Fe, Mn, Zn, Cu, Cd and Pb) behaved non-conservatively with addition in the estuary. Nevertheless, dissolved Pb was apparently removed from the estuary in the wet season. Particulate Al and Fe were derived mainly from continental weathering and their transports through the estuary depend highly on the distribution of total suspended matter (TSM). During the dry season, the occurrence oxygen-deficit condition in the low salinity region and possible pollution from the San-Wei fishery harbor likely determined the distributions and solid-solution partitions of Mn, Zn, Cu, Cd and Pb in the estuary. Distributions of dissolved trace metals in the Kaoping coastal zone were significantly influenced by terrestrial inputs from the Kaoping River. Seasonal variations were attributed largely from the mixing between river water and sea water in the mixing layer and sediment resuspension from canyon bed. The column integrated dissolved and particulate metals were generally higher in the summer season than in other seasons. The difference was especially pronounced in nearshore stations. Concentrations of dissolved Mn, Zn, Cu and Pb increased generally with depth, reflecting the effects of resuspension and lateral transport of bottom sediment. Dissolved Zn and Cu concentrations correlated well with dissolved Mn concentration, but particulate Zn and Cu correlated poorly with particulate Al, implying that distributions of Zn and Cu were controlled by terrestrial inputs and biogeochemical processes in the Kaoping Canyon. Positive and negative correlations are found between dissolved Cd and nutrients (N+N¡Aorthophosphate) and between dissolved Cd and dissolved organic carbon (DOC), respectively, indicating that Cd is a nutrient-type metal and controlled biogeochemically in the Kaoping Canyon. Specific events such as typhoon and earthquake influenced significantly the distributions of trace metals in the Kaoping coastal zone. The integrated suspended-matter and suspended-metal concentrations showed an order magnitude higher during the typhoon season than in the normal summer season. Under the influence of earthquake, the TSM values of the bottom waters were much higher (2-7 folds) during the post- earthquake cruise (Jan/2007) than in the normal season (Jan/2006). Meanwhile, particulate Al, Fe, and Mn can increase up to 2- to 10-folds after earthquake in the bottom layer of canyon. Metal enrichment factor (EF) is an indicator of metal pollution. The EFs show an order magnitude higher in the dry season than in the wet season both in the estuary and canyon. Such seasonal patterns clearly indicate the impacts of local and river inputs on metal distributions in the estuary and canyon.
