摘要

Long-term study of the species composition and numbers of phytoplankton in the coastal waters of Peter the Great Bay, the Sea of Japan, revealed the seasonal and year-to-year dynamics in the abundance of the diatomThalassiosira nordenskioeldiiCleve, 1873. The species dominated the phytoplankton in the winter and early spring, growing under the sea ice at a surface water temperature of -1.8 to 0 degrees C and a salinity of 33.0-35.0 parts per thousand. The observations of the long-term population dynamics ofT. nordenskioeldii(2005-2015) showed a decline in its significance in the phytoplankton community compared to that in the 1970s, resulting in a complete loss of dominance in winter-spring plankton assemblages. The year-round occurrence ofT. nordenskioeldiicells in the studied area, as well as data from the literature, indicate that the species has a tropical-arctic-boreal distribution. Positive correlations were found between the surface water salinity, the content of organic matter in seawater, and the abundance ofT. nordenskioeldii.A negative relationship with nitrate concentration reflected a depletion of nitrates caused by the mass growth ofT. nordenskioeldii.
