The paper contains the study of heavy metals in three species - Sargassum miyabei , Sargassum pallidum , Cystoseira crassipes in the coastal waters of the Posyet Bay. The analysis of the spatial distribution of trace elements revealed the highest contents of zinc, copper and nickel in the Troitsa Bight, due to recreational pressure and a high concentration of nickel and cadmium in Sivuchya Bight that was caused by transboundary atmospheric transport. All of detected concentrations exceed natural background values for the North-Western part of the Sea of Japan. The authors show that there has been a distinct change in the environmental situation in the the Posyet Bay since 1998: the concentration of lead has sharply decreased, the content of zinc, copper and cadmium has decreased, it could be connected with influence reduction in the free economic zone, located on the Chinese side on the Tumannaya River.

Oscarella malakhovi sp. nov. is described from the waters of Peter the Great Bay (northwestern Sea of Japan, Russia) at depths between 0.4–4 m from a rocky coast. This is the first record of the genus Oscarella from the North-Western Pacific. The new species is characterized by its pinky-beige to yellow color, undulating appearance, lumpy, microlobate surface, soft, slimy consistency, two particular kinds of cells with inclusions (vacuolar and granular cells), and of two kinds of endobiont bacteria. The new species of Oscarella is clearly different in cell, endobiotic bacteria content, and external morphology from all previously described species of Oscarella.

Long Term Variations

This review aimed to summarize original and published data on the bloom events caused by toxic diatoms of the genus Pseudo-nitzschia and to assess long-term variations in the composition of bloom-forming species in the northwestern Sea of Japan during 1992−2015. This information is crucial to understanding the potential threat of toxic blooms and their effects. A change in species composition was observed within the genus Pseudo-nitzschia: it was dominated by Pseudo-nitzschia multiseries during 1992–1993, 2002, and a shift towards the dominance of Pseudo-nitzschia multistriata and Pseudo-nitzschia calliantha occurred in 2005–2015. We assume that the increased sea surface temperature recorded from Amursky Bay in the period of 1998–2009 compared to the data of 1980–1989 might be one of the causative factors for the shift observed. The absence of highly toxic Pseudo-nitzschia multiseries among the bloom-forming species is considered as one of the possible explanations for the lack of damage from the blooms of Pseudo-nitzschia over the past 15 years in the study area.
