Hermann Blaschko,Walter G. Levinematic decrease in the water transparency was observed during 1986–1992. This coincided with significant changes of the spectral distribution of optical parameters. The main reasons of such changes are eutrophication, influence of the biological invader . on the sea ecosystem, and the natural 11 year solar cycle.

Organic matter in this unit appears to be heterogeneous in composition, but probably mainly of marine origin. Low Mn contents of Unit 2, which are comparable with that of Unit 1, imply deposition of this unit under unoxic bottom wa

The annual cycle of plankton dynamics in the central Black Sea is being studied by means of an one-dimensional vertically resolved physical-biological upper ocean model, involving interactions between inorganic N (NO., NH.), phytoplankton and herbivorous zooplankton, and detr
