Geographic Information Systems (GIS) is an innovative mapping technology used around the world to identify boundaries of geographic features, infrastructure, and myriad uses across the landscape. Historically a land-based application, the use of GIS in coastal ecosystems is growing (Nath et al. 2000, Babcock et al.2005, Dempster and Sanchez-Jerez 2008). Coastal areas are heavily used for shippi...

ABS11tACT: A study to measure the heavy metal pollution level in the sediment of coastal and offshore area indicates that high concentration of heavy metals were found around Manora channel and eastern coast of Karachi. In comparison with coastal areas, relatively low concentration of heavy metals was recorded in the offshore area. The result shows that sewage and industrial wastes are the main...

Sustainable management of highly dynamic coastal topography with fast moving sand dunes, eroding shoreline and anthropogenic changes to bathymetry and beaches represent significant challenges for coastal management. Modern mapping technologies bring capabilities to monitor this dynamic environment with unprecedented spatial and temporal detail. The general research strategy for coastal areas [1...

The natural environment is unequivocally the life support for all human systems. Far for being a luxury available only to those who can afford it, successful environmental management will increasingly become the basis for the success or failure of the economics and social systems of entire countries. In the last two decades, concern has been expressed about possible effects of climate change in...

Otolith chemistry of juvenile and adult individuals of the Brazilian snapper Lutjanus alexandrei was measured to assess the utility of natural markers for investigating individual movements. Individuals were collected over a 3-year period (2010-2012) along the north-eastern coast of Brazil from both estuarine (juvenile to sub-adult stages) and coastal (sub-adult to adult stages) areas. Six elem...
