variety of glacigenic sediments together with glacial marine units and littoral deposits. Lake muds are also fairly common. All three areas possess very long records that may extend to the early Quaternary and Pliocene.
Evidence from terrestrial sections, ice cores, and marine cores are reviewed and used to develop a scenario for environmental change in the area of the extreme northwest North Atlantic during marine isotope stages 5 and 4.
During the Heidelberg-Ellesmere-island-expedition in 1978 the summerly water balance of this high arctic catchment area with continuous permafrost was investigated. (D'après l'Ed.).
This paper deals with geological action of drift ice on the marine littoral environment. The spatial, temporal and physical characteristics of sea ice cover are examined, together with their effects in the littoral zone, especially in four areas
from areas southeastward. Climatic cooling in more recent millennia (3500 yr B.P. to the present) is indicated by the appearance and persistent growth of Tsuga mertensiana and Selaginella selaginoides along this portion of the Gulf of Alaska coastline.
thickness of 3300 m on Fosheim Peninsula, Ellesmere Island, contains numerous thick seams of coal. The coal is highly variable in quality... Inferred resources within the area of study are calculated as 30.000 million tonnes of which 15.000 million tonnes
the Valleys: Slaklidalen and Revdalen. It proved that the Hornsund region was completely covered by the Würm glaciers about 45-40 thousand years BP. The following Würm glacier advances occupied smaller areas. The glaciers probably contacted
with the Scandinavian ice sheet of that time through the Barents Shelf ice sheet. The following glacier advances in the described area occurred about 11-10 thousand years BP and in Late Holocene: at 2.5-2 thousand years BP and during Ice Age. (AA).
The research strategy of the AA. combines geologic mapping and soil studies of drift sheets in ice-free areas. They differentiated drift sheets by changes in surface morphology, surface boulder weathering and soil development. The AA. conclude
Piston cores and single-channel seismic reflection data were collected during the Deep Freeze 85 and 86 expeditions to determine the late Quaternary history of the area. Seismic data in the bay show a rugged seafloor, with numerous deep troughs
and growth of the area of the subsidence and associated uplift to regional barriers between the basins. Other events : ice cover formation in the polar basin| seasonal freezing of the ground| permafrost developed since the Middle Pliocene.
and environmental impact on the relief evolution. Sedimentary formations structure indicates that the sea shelves in the Eastern Soviet Arctic are not only zones of transit of sediments but also a very large area of sedimentation. - (L'Ed.).
Soils studies in south Greenland reveal a two sequence soil profile. During the settlement period of the Norsemen about 985-1450 a. c. the area was for the first time used for agricultural purposes. In the uppermost horizon of the old zonal soil

is not a major denudational process in this environment. Some support is given to the concept of partial area contribution to run-off in permafrost regions.
lateral movements in the Early Cretaceous. During this period, the Antarctic Peninsula area occupied an important paleogeographical position, near the junction of major new seaways that were opening between South America and Africa, along the eastern coast
, and the surface of the Moho discontinuity. The rift zones are commonest in the lows of bedrock relief related to extensive intra and pericontinental structural depressions. This suggests that the Antarctic shelf, which is about 40 % of the total area
areas and laid Winter Harbour Till up to 150 m above present sea level on the north coast of Victoria Island. The contemporary sea-level was 50 to 100 m higher than present. A maximum age of 10,340150 yr BP for the till, and thus for the ice shelf
