| Zusammenfassung |
The ten years of the SeaWiFS satellite surface chlorophyll concentration
observations, presently available, were used to characterize the
biogeography of the Mediterranean Sea and the seasonal cycle of the surface
biomass in different areas of the basin. The K-means cluster analysis was
applied on the satellite time-series of chlorophyll concentration. The
resulting coherent patterns were then explained on the basis of the present
knowledge of the basin's functioning. Winter biomass enhancements were shown
to occur in most of the basin and last for 2–3 months depending on the
region. Classical spring bloom regimes were also observed, regularly in the
North Western Mediterranean, and intermittently in four other specific
areas.
The geographical correspondence between specific clusters and regions
showing high values of mean chlorophyll concentration indicates that, at
least in the Mediterranean Sea, accumulations of phytoplankton are observed
only where specific temporal trends are present. |
