This paper presents the results of study of diatoms in each centimeter of sediments in cores A12-4 and A12-5 from Amur Bay (Sea of Japan) that have formed over the last 150 years. Diatom algae show significant changes in the quantitative content and ecological structure of the assemblages, which reveal the conditions of sediments accumulation. The study showed that in lithologically homogeneous sediments, with relatively high sedimentation rates and the absence of bioturbation, sharp short-term
