THE DEEP-WATER PLANKTON OF THE SEA OF JAPAN (O Planktone Glubinnykh Vod Yaponskogo Morya),
Abstract
Deep waters of the Sea of Japan are inhabited by cold water eurybathic species. True abyssal species are lacking there. Despite the fact that interzonal species occur in the Sea of Japan, and in large numbers, the plankton biomass of deep layers in this sea is very small owing to the lack of true deep sea animals. A large number of deep sea species of the ocean raises up to low depths during either ontogenetical movement or diurnal migrations, so that the shallowness of the strait cannot hinder the penetration of these species into the Sea of Japan. The introduction of these species into the Sea of Japan is obstructed mainly by the cold winter surface waters which differ in their structure from the warmer deep waters of the adjacent seas. The basin of the Sea of Japan being of an ancient origin, was connected with the depths of the ocean. The absence of true deep-sea animals in the Sea of Japan may depend on contemporary aberrant physical and chemical properties of its deep waters. (Author)
