Resumo

Based on results of field observations in August 1998, July 2000, and August 2001 composition and quantitative distribution of coccolithophorids in the middle part of the Eastern Bering Sea shelf between 56°052'N and 59°019'N was characterized. Emiliania huxleyi abundance, biomass, and population structure as well as role of species in the coccolithophorid community and phytoplankton as a whole were evaluated. Abundance of the species in the upper mixed layer in bloom areas was 1-3 mln cells/l and biomass made up 30-75 mg C/m**3. E. huxleyi share in total phytoplankton numbers and biomass at that reached 98% and 84% respectively. Significant spatial heterogeneity of E. huxleyi, quantitative distribution and population size structure, as well as asynchronism in population development in neighboring parts of the bloom area were shown. The time period, during which population structure in certain part of the area shifts from domination of juvenile cells without coccoliths to a phase of active detritus formation with dying coccolithophorid cells involved, may be estimated as two weeks. A conclusion is made that after anomalous E. huxleyi bloom in 1997 mass development of coccolithophorids became a characteristic feature of phytoplankton community's seasonal succession in the middle part of the Eastern Bering Sea shelf.
