despite the fact that coastal areas are benefiting from verity of biological resources of marine and inland systems, they are exposed to destructive threats from both systems. hence, coastal areas are the most vulnerable sectors in the world. population growth, tourism, urbanization, and industrialization are the most important factors in increasing pressure on the coastal and marine areas. ide...

The existing knowledge regarding seawater intrusion and particularly upconing, in which both problems are linked to pumping, entirely relies on theoretical assumptions. Therefore, in this paper, an attempt is made to capture the effects of pumping on seawater intrusion and upconing using 2D resistivity measurement. For this work, two positions, one perpendicular and the other parallel to the se...

A major spawning ground of the European anchovy (Engraulis encrasicolus) population in the Bay of Biscay is located near the mouth of the Gironde estuary. Variations in the river discharge affect the supply of nutrients to the coastal marine area encompassing anchovy spawning grounds. Two “Pegase” cruises (May–June 1997 and 1998) observed two contrasting situations: with and without a superfici...

We studied the effects of pumping surface water down through pycnocline (i.e. artificial ventilation) on hydrodynamics, oxygen concentrations, hydrogen sulfide, and nutrients in two anoxic coastal basins (Lännerstasundet Sandöfjärden). In addition, a corresponding laboratory aquarium experiment, less saline entrained dense bottom with mixing ratio 6.8 illustrated dispersal below pycnocline. Oxy...

Tabularia populations collected at a coastal site in Lake Erie, near Cleveland, Ohio, USA exhibit highly abnormal morphology. Frustules may be bent, asymmetric, have irregular striae patterns, irregular margins, or any combination of these characters. The majority of specimens in the collection are abnormal to some degree. Although specimens are so atypical that identification is difficult, rel...

Outdoor substations placed in coastal areas are affected by saline environments. In the technical literature it is found extensive information regarding insulations problems in presence of saline environments [1]. The accumulation of salts and other contaminants promotes the onset of partial discharges on the devices subjected to very high voltages. Insulators are also affected by this phenomen...

douala metropolitan city loated in the littoral province of cameroon,has experienced a rapid urbaniation and industralisation. the city depends heavily on groundwater as a resource. due to ubiquitous sources of pollution, groundwater quality and contamination has become an imprtant issue for this urban groundwater supply. this study uses the major ion chemistry of groundwater together with t...
