"Coastal grab" refers to the contested appropriation of coastal (shore and inshore) space and resources by outside interests. This paper explores the phenomenon of coastal grabbing and the effects of such appropriation on community-based conservation of local resources and environment. The approach combines socialecological systems analysis with socio-legal property rights studies. Evidence of ...
Spatially variable selection has the potential to result in local adaptation unless counteracted by gene flow. Therefore, barriers to gene flow will help facilitate divergence between populations that differ in local selection pressures. We performed spatially and temporally replicated reciprocal field transplant experiments between inland and coastal habitats using males of the common blue dam...
Water quality models can be effective tools to simulate and predict pollutant transport in coastal water environment, which can contribute to saving the cost of labours and materials for a large number of industrial development in the coastal region. Therefore, water quality models become an important tool to identify water pollution and the final fate and behaviours of pollutants in coastal en...
Mercury speciation in coastal sediments from the central east coast of India by modified BCR method.
This is the first study to describe distribution and speciation of Hg in coastal sediments from the central east coast of India. The concentrations of Hg in the studied sediments were found to be much lower than the Hg concentration recommended in coastal sediments by the United State Environmental Protection Agency and the Canadian Council of Ministers of the Environment for the protection of ...
Numerical modeling is carried out to investigate the spreading pattern of industrial wastewater released from coastal refineries and power plant into thePersian Gulf. The pollutant sources due to the wastewater outfall of the coastal industrial plants are completely considered in the model. The effects of sources are inspected on the adjacent marine environment. The numerical model is developed...
The intersection of human health and the ocean occurs overwhelmingly in the coastal zone. The coastal zone extends from the upland penetration of tidal rivers to the edge of the continental shelf, which can extend 100 miles or more beyond the coast itself. The world's coastlines, including temperate, tropical, and polar coasts, have been estimated to total about 372,000 miles (Smithsonian Insti...
Coastal environment is controlled by a complex interaction of physical, chemical, biological, and geological processes. Physical processes are responsible for controlling the transport and distribution of all dissolved and suspended matters in coastal waters. A comprehensive understanding of these processes is crucial to the design and implementation of management strategies that track ecosyste...
My objectives for this study were the following: (1) To work with Drs Holliday and Donaghay to deploy autonomous acoustical and optical instrumentation at eight coastal US sites, (2) to quantify the temporal occurrence and spatial distribution of thin planktonic layers at eight coastal US sites, (3) to assess the hydrography at each of the coastal sites in order to provide a physical context wi...
