Satellite observations of the Black Sea reveal a complex, nearly chaotic flow field in coastal waters while along the Crimea coast a major upwelling prevails in summer. Ship-born data suggest downwelling occasionally occurs, advecting polluted riverine sediment to the centre of the Black Sea. The marine ecosystems of the Black Sea have been subjected to strong anthropogenous pressure the last 50 years. The resulting environmental degradation is so severe that it affects economic and social developments as well as human health and a decrease in biodiversity and productivity. While the whole Black Sea is increasingly eutrophicated, one-third of the area is subject to increased sedimentation. Locally this decrease is often associated with an increase in heavy metal pollution though in open areas storm waves help alleviate the pollution. Visualization of the data helps to quantify the spatial scales of ecological processes and anthropogeneous loadings and demonstrates that the anthropogeneous loadings degrade the coastal ecosystems of the Black Sea at both the large (regional) and local scales.
