| الوصف: | The export production of coccolithophores has been measured from Black Sea, North Aegean Sea, Cretan Sea, South Cretan margin and Ionian Sea, and compared in order to define the spatial and seasonal variability in theirassemblage composition. Α sediment trap mooring has been deployed for one year (10/2007- 9/2008) at 1000 m water depth, in western Black Sea. The maximum coccosphere fluxes, with almost monospecific assemblage of Emiliania huxleyi, have been recorded during May, June and September (max. 3.2 x108 coccospheres m-2 day-1). The seasonally controlled coccolithophore patterns are strongly related to those of sea surface temperature and accumulated rainfall in the area, triggering riverine nutrient input Coccosphere fluxes in North Aegean Sea have been calculated from a sediment trap deployment at 500 m (1/2011-12/2011). E. huxleyi is the dominant species, followed by Rhabdosphaera spp., Syracosphaera spp. and Florisphaera profunda as minor assemblage components. Maximum fluxes have been observed in February and June (max. summer 2.9 x105 coccospheres m-2 day-1). A single mooring with two sediment traps (500 and 1700 m) was deployed at the southern margin of the Cretan Sea (Triantaphyllou et al., 2004). The results obtained from 500 m depth show that the highest flux values were observed between late March to late June (max. 9.4 x105 coccospheres m-2 day-1). The pattern was characterized by three main phases that correlate well with the gradual increase in SST from January till September. Coccosphere sinking assemblages were characterized by high abundances of E. huxleyi, followed by F. profunda, Rhabdosphaera spp. and Syracosphaera spp. Six moorings have been deployed at different sites along the south–west margin of Crete, providing a total of eight sediment-trap time series (6/ 2005-5/2006), (Malinverno et al., 2009). Maximum coccosphere fluxes were recorded in between March to June (4.3 x 105 –3.4 x106 coccospheres m−2 day−1), featured by dominance of E. huxleyi and subordinate Helicosphaera carteri, ... |
