Heavy metals (Cu, Zn, Pb, Cd) in sediment, Zooplankton and epibenthic invertebrates from the area oed to corresponding species from other geographical latitudes. Cadmium concentrations were relatively low, ranging from 0.13-0.42 μg g. D.W. in the bivalve molluscs . and from 0.04-0.27 μg g. D.W. in the shrimp . Also in the crab species . sp. and . sp., the cadmium concentrations were low, varying

Primary production and distribution of phytopigments in the water column and sediments on the upwel in the coastal water type. The pigments in the surface sediments did not reflect the respective overlying water types due to the increasing accumulation of pigments at the offshore stations of the northern transect. This accumulation seems to correspond with the progressive reduction of the benthic

The trawlfauna of the Mauritanian shelf (Northwest Africa): density, species composition, and biomaistribution of the infauna and the hydrographical conditions on the Mauritanian shelf. Being a demersal fishing area, density and biomass of the epifauna on the shelf are compared with that of the demersal fishing grounds in the southern North Sea. The result of this comparison shows that, except fo

The Shores of the Auversian Seaal upwelling and seasonal heating made the thermocline upper limit rise towards the surface and upwelling waters reach the shallowest parts of the shelf. In the northern part of the study area upwelling phenomena were observed in the subsurface layers below 50 m depth; upwelling water did not reach

Ömer Can Ünüvar,Ercan Selçuk Ünlühis difference between leaves and slides was probably caused by a storm at the day before the end of the experiment, and by the higher periphyton density on slides as compared with leaves. As visual inspection during the experiment showed clear differences in appearance of leaves inside and outside
