摘要:

Taking into consideration new data in paleoglaciology, geomorphology, till stratigraphy and the provenance of erratics in the northern periphery of Western Siberia, and data on the absolute ages of lacustrine sediments, the authors conclude that vast glacier‐dammed lakes, contemporaneous with the last (Sartan) glaciation, existed in the West Siberian Plain. These lakes discharged southwestward via the Turgay Gate into the Aral‐Caspian basin.

摘要:

On the basis of geomorphological and geological data as well as radiocarbon dates, the author rebuts the hypothesis of the existence during the Late Pleistocene and Early Holocene of an extensive ice sheet on the Barents and Kara shelves and the adjacent northern lowlands.

摘要:

The paper examines the principal characteristics of the circulation of water in the Southern Ocean, including the presence of a strong Arctic Circumpolar Current, the existence of a well defined Antarctic Polar Front and the formation of cold bottom waters off Antarctica that then enter the meridional circulation of the World Ocean. An examination of the results of theoretical investigations, numerical experiments with models and observations in the ocean lead to a number of conclusions regarding the nature of the Antarctic Circumpolar Current and the Antarctic Polar Front, their variability, and the role of the meridional circulation in the dynamics of waters in the Southern Ocean.

摘要:

Human adaptation problems in polar regions have been investigated since 1967 by the Department of Polar Medicine of the Arctic‐Antarctic Institute, with the Siberian branch of the Academy of Medical Sciences USSR playing a supervisory role since 1974. Efforts are being made to systematize the physical and psychological requisites for the selection of polar‐station personnel. A review of Soviet polar activities shows a generally high health index, with the work of 72% of Antarctic personnel and 82% of North Pole drift station personnel unimpaired by illness.

摘要:

In view of contradictory data on the mechanism of heat exchange in human organisms in polar regions, an attempt was made to investigate differences in thermoregulatory reactions during a year‐long drift in the Central Arctic and, after the men's return, in a meteorological chamber. The investigation included the total respiratory gas exchange, the electrical activity of neck muscles, body temperature, skin temperature and radiative‐convective heat loss. It was found that drift‐station personnel acquire a certain resistance to wind and cold during their year‐long stay in the Arctic, and that this resistance vanishes nine months after their return.

摘要:

The physical‐climatic and sanitary‐hygienic conditions at Leningradskaya Station, established by the Soviet Union in 1971, are described. Climatic conditions are affected by sharp fluctuations in weather elements, with relative humidity ranging from 20% to 100% in the course of the year, atmospheric pressure from 1018 to 910 mb, air temperature from +5.9° to ‐42°C, and winds of 15 m/sec or more on about 50% of the days. Traumas and colds account for more than half of the incidence of disease. Muscular discontfort (myositis), neuralgic pain in joints (arthralgia) and nerve‐root inflamation (radiculitis) are common. Dental problems are also frequent despite regular examinations.
