Проведены химико-экологические и микробиологические исследования современного состояния поверхностных прибрежных вод зал. Восток (Японское море). Наиболее напряженная экологическая ситуация отмечена в бухте Гайдамак, в районах у Волчанецкой протоки и устья р. Литовка. Протока, а также приустьевая зона р.Литовка являются главными тревожными участками в морском заказнике Залив Восток . The current state of the Vostok Bay water area (the Sea of Japan) is estimated using hydrochemical and microbiological indicators. The most intense environmental situation was noted for Gaydamak Bight, the area near the Volchanets duct and the mouth of the Litovka River. The duct, as well as the mouth of the Litovka River, are the main alarming sites in the Vostok Bay marine reserve.


Although the primary subject of the Symposium was continental drift, this is only one aspect of a larger problem. Eventually, consideration of changes in magmatic, metamorphic and tectonic activity through the history of the crust should enable us to put forward a hypothesis to account for the behaviour of the upper parts of the Earth through geological time. As had been pointed out, most geophysical methods provided information about the current state of the Earth and part of the great value of palaeomagnetic studies lay in the fact that they produced information about the past. Some information about the behaviour of possible convection cells during continental drift could be obtained from other long-term changes in the crust. The incidence of magmatic and metamorphic activity gave some indication as to the distribution of regions where there had been an unusually high accession of heat in the past.
