Abstract

Results of satellite monitoring campaign conducted in the northeastern Black Sea and eastern Azov sea coastal zones in 2006-2007 are presented. The monitoring was focused on the detection and analysis of biogenic and anthropogenic pollution of the sea surface and the near-surface layer, including oil pollution. The work focuses on quasi-operational mapping of key water state parameters, analysis of meteorological conditions and local circulation pattern and their impact on spread and drift of pollutants and deducing typical local modes of pollution evolution. Data in visual, infrared and microwave ranges from 9 satellites provides the basis for the processing and analysis. These are complimented with ground data from meteorological stations on the shore and results of satellite data processing of previous periods. Over ten information products are elaborated every 10 days and monthly, including maps of sea surface surfactant film pollution, phytoplankton and algae distribution, chlorophyll-a concentration, sea surface temperature, etc. as well as summary maps of sea surface state and pollution. The monitoring provides rich material for the study of hydrodynamic processes in the region, in particular for the detailing of water circulation. The effect of water circulation patterns and river outflow intensity on the dynamics of biogenic films is investigated. Three types of pollution drift and evolution patterns depending on local water circulation modes are defined. Areas commonly affected by pollution are determined and usual sources of such pollution are established.
