摘要

Diatom community structure in the offshore Tsushima Current area of the Japan Sea was studied from 1972 to 1999 in relation to temporal variability of the upper water environment. We observed a distinct change in the community structure in spring during the 1980s, the period after the 1976/77 climate regime shift which has been reported to occur in the vast areas of the North Pacific. Chlorphyll a(chl a)concentration and chl a per cell were markedly low, and summer species include- Ing Pseudonitzshiz spp. dominated the diatom community in spring during the 1980s.
