Coastal runoff and plumes in the Mediterranean sea from the historical CZCS archive
In this paper a multi-annual time series of high-resolution sea surface colour data derived from the historical Coastal Zone Colour Scanner (CZCS) archive has bee used to assess the space/time variability of near-costal features in the Mediterranean Sea. The CZCS data were processed to apply sensor calibration algorithms, to correct for atmospheric contamination, and to derive chlorophyll-like pigment concentration. Individual remapped images were generated for each available day, and to generate monthly and annual means. The composite images show marked differences in the distribution of water constituents between the oligotrophic character of open sea waters and the high concentrations of coastal zones, influenced by persistent mesoscale features, river plumes and runoff patterns. Seasonal and interannual variability appears to be significant. Enhanced patterns and higher concentrations occur over most of the basin in the cold season, when climatic conditions could be most favourable to coastal runoff and vertical mixing. The observed range of coastal phenomena suggests a relationship between the resulting basin-wide seasonal patterns and the climate cycle of the Mediterranean region.
