The phenomena of saltish water paradox in amphibian geoecosystems of foreland, with a specific type of ecosystems characterized by low biodiversity and high biological productivity is considered.

Relying on the analysis of vertical distribution of phosphate and silicate as well as of vertical concentration gradients of these hydrochemical parameters above the mud volcano on the northwest Black Sea shelf the author came to a conclusion that mud volcanoes can be an endogenous source of silicate.

The procedure of assessment of water areas ecological state using pollution load index (PLI) was applied to elucidate the pollution status of the Sevastopol Bay. The index allows assessing the quality of environment on the ten-point scale from 1 to 10 i.e. from a severely contaminated water basin to nearly unpolluted one. The ecological status of the Sevastopol Bay was clarified, its partition and comparison with both a number of the European Bays and estuaries and the Australian estuary were accomplished using the PLI.

The influence of the drain of the Chernaya River to the forming of the water-salt regime of waters is examined on the basis of data of the regime observations of the aqueous drain and content of chemical indices. The calculation of the extension of biogenic elements into the Sevastopol Bay is executed.
