Description
Summary:In the south Sakhalin area, the greatest quantities and varieties of phytoplankton are observed off the west coast of Sakhalin, the smallest in Zaliv Terpeniya. The phytoplankton consists almost exclusively of diatom algae and dinoflagellates. Neritic species prevail over oceanic forms. Phytogeographically, boreal forms prevail, making up more than 50% of the total number of species. The percentage of temperate thermophilic and thermophilic species varies from place to place, the maximum being reached (29.3%) in the southern sector of the Sea of Okhotsk, then following the west coast of south Sakhalin (27.1%). Admixture of cryophilic forms (arctic and arctic boreal) is most clearly pronounced in Zaliv Aniva (19%), most weakly off the west coast of south Sakhalin. The quantity of phytoplankton is extremely variable during the summer season (July-Sept.). In the Kurile Islands area, the phytoplankton is represented mainly by diatom algae and dinoflagellates. The greatest diversity was observed in the South Kurile Strait. Neritic species prevail over oceanic forms. Boreal species prevail. The percentage of temperate thermophilic and thermophilic species in phytoplankton is rather high (27.7-28.4%). The quantity of phytoplankton in the South Kurile Strait is rather high, reaching 700-900 thousand cells per 1 liter of water. In the Pacific area the quantity is not uniform: near ostrov Shikotan and Zelenyy the quantity is much higher than far off the coast. In summer the greatest development of phytoplankton was observed in the coastal belt of the southern Kurile Islands.
