Zusammenfassung |
The diversity and distribution of epipelagic metazooplankton across the
Mediterranean Sea was studied along a 3000 km long transect from the eastern
to the western basins during the BOUM cruise in summer 2008. Metazooplankton
were sampled using both a 120 μm mesh size bongo net and Niskin bottles
in the upper 200 m layer at 17 stations. Here we report on the stock, the
composition and the structure of the metazooplankton community. The
abundance was 4 to 8 times higher than in several previously published
studies, whereas the biomass remained within the same order of magnitude. An
eastward decrease in abundance was evident, although biomass was variable.
Spatial (horizontal and vertical) distribution of metazooplankton abundance
and biomass was strongly correlated to chlorophyll-a concentration. In
addition, a clear association was observed between the vertical distribution
of nauplii and small copepods and the depth of the deep chlorophyll maximum.
The distinction between the communities of the eastern and western basins
was clearly explained by the environmental factors. The specific
distribution pattern of remarkable species was also described. |
