Abstract

The purpose of this study is to investigate the interannual variability of the Black Sea suspended matter concentrations based on satellite data. The spatial and temporal variability of the bio-optical parameters are investigated by satellite data analysis. To analyze the interannual variability of suspended matter concentration on the northwestern shelf of the Black Sea, the combined monthly fields of the backscatter factor (BBP) for the period 1998-2010, obtained from the data of the SeaWiFS scanners, MODIS, MERIS are presented in a uniform spatial resolution grid of 4.6 km. empiric orthogonal function (EOF) analysis is applied to these data arrays with the aim to classify the spatial variability of BBP signal. As a result, the characteristics of the interannual spatial-temporal variability of the suspended matter concentration are given by four Empiric orthogonal function maps. They describe around 52% of summary suspended matter variance on the northwestern shelf of the Black Sea and thus its define the main regions (sources) of matter input. The influence of the Danube water inflow and suspended matters transport on the northwestern part of the Black Sea are discussed. The relationship between interannual variability of the suspended matter concentrations and large-scale atmospheric circulation processes was compared via North Atlantic Oscillation index.
