the usage and production of polychlorinated biphenyls (pcbs) was banned in argentina in2002, approximately twenty to thirty years later than in other countries. a total of 29 sediment samples (upto 14 m deep) were analyzed for a mix of seven individual pcbs in a time series for over more than one year in twelve selected locations, including harbors, recreational docks and several industrialized...

The present-day study of coastal morphodynamics involves a dynamic field of research in which combinations of coastal monitoring, process-oriented laboratory and field work, modelling studies and Data-Model Integration techniques enhance our capabilities to understand and predict coastal systems and their evolution. Innovations in coastal research and coastal instrumentation strongly interact a...

There are major differences in the bioproduction potential of different coastal areas. The aim of this work is to review and discuss simple, operational criteria related to the bioproduction potential of coastal areas and to present and motivate an Index of Biological Value (IBV) for coastal management. This index is based on two key variables, which can be determined easily from bathymetric ma...

iran is located between two lithospheric plates (euroasia, arabian) and these two plates converge toward each other with a velocity of 25 mm/yr rate. shortening that produced from this convergence with makran subductin shows faulting and folding in zagros orogenic belt, alborz and kopedagh in north and sliding in sum strike slip faults with north-south trend in central iran. the nw-se trending ...

Climate change related Sea Level Rise (SLR) increases the vulnerability of coastal ecosystems by posing threat to many coastal cities, urban centres and coastal population in developed as well as in developing countries. Coastal areas are predominantly rich in resources, easily accessible and facilitate infiltration of people and investments. The 8118 km long coastline in India is characterized...

in western coast of gujarat destructive tsunamis have been generated from large earthquakes along the makran coast, chagos ridge and kutch region in the past. although the historical record is incomplete, it is believed that such tsunamis were destructive on the coasts of india, pakistan, iran, oman and sri lanka and possibly had significant effects on islands. the most significant tsunamigenic...
