摘要

This investigation was carried out in the surface water layer of some coastal and open-sea zones of the Black Sea in May 2013 when a spring bloom of Emiliania huxleyi was developing. The numbers of E. huxleyi in the blooming sea surface varied from 1.3 to 4.3·106 cell/l amounting on the average to 94 % of the total phytoplankton abundance. The bloom emerged as a response to favourable light, temperature and nutrient conditions which have accelerated the phytoplankton growth to 0.80 – 1.44 d-1 while the predatory pressure of microzooplankton on this coccolithophore remained low. High net growth rate of the phytoplankton (0.40 –1.00 d-1) and low ratios of the specific microzooplankton grazing rate to the specific phytoplankton growth rate (34% on the average) in the seawater area can be interpreted as the evidence of beginning bloom.
