Since the sensational discovery of a living coelacanth off the east coast of South Africa, the geographic distribution of viable coelacanth populations has been a subject of debate. In the past, the coelacanths off the African mainland were thought to be strays from the Comoros because most coelacanths captured were caught in the waters surrounding the Comoros archipelagos. However, in recent y...
The Water Framework Directives aims a reduction in concentration of hazardous substances in the marine environment. Consequently, there is a need to distinguish between anthropogenically influenced metal concentrations from natural background levels. To better achieve this goal in the Portuguese coast, dissolved and particulate trace metal (TM) concentrations along the Portuguese coast were det...

the concentration of selected trace metals (fe, cd, cu, pb, and zn) in 30surface sediments were measured using atomic absorption spectrometer to investigatethe spatial and seasonal variations of trace metals along kanyakumari coast, india. toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...
eight selected heavy metals (cu, zn, pb, cd, cr, mn, fe and al) in surface and sub-surfacesediments in the northern coast of sfax (tunisia) were studied in order to assess the sediment quality and tohighlight the anthropogenic contributions to heavy metal distributions in the two study sediment levels.multiple chemometric approaches based on geographic information system (gis), enrichment facto...
Abstract The purpose of this research is to design and identify some of the natures and characteristics of high-resolution surface currents in the Northern Indian Ocean. The pattern of 3D circulation of the Wind-driven surface currents, Sea surface temperature (SST) and Sea Surface Salinity (SSS) distribution in the Northern Indian Ocean using The MIT general circulation model (MITgcm) with ho...
Since June 1986, the University of Pennsylvania has been under contract with the Coast Guard to provide support for the Coast Guard's KSS (knowledge-based decision support systems) project. A principal output of the KSS project has been Max, a DSS shell or environment, originally designed to support modeling tasks during decision making for ship acquisition. Max is innovative in a number of way...
Silver pomfret, Pampus argenteus is an economically important seafood species. The fishery resource of pomfret in Indian waters shows a dwindling catch since the last few years and the pomfrets caught were mostly undersized which calls for immediate attempts for management of resources. An accurate definition of population structure is important for management of this species. The genetic stock...
geographical location and climatic condition in the northern coast of persian gulf provided a suitable condition for the spread of epidemic diseases and their continuity. in qajar period, increased relations with india, mesopotamia and lack of health facilities caused the death of many residents in these areas. at the beginning of reza shah’s reign and the government’s attitude towards moderniz...
the volume and surface area of the coast is a function of basin water levels. recognizing the factors of coastal geomorphologic changes could have a pivotal role in planning and managing the coast. effective factors in the formation and evolution of geomorphologic factors such as geological, tectonic, paleoclimatic, paleoclimatic and sea level changes have been considered in this study and the ...
