Rapid changes in ocean circulation and heat flux in the Nordic seas during the last interglacial period
Article Abstract:
The temperature changes on adjacent continents may be responsible for the changes in the ocean circulation and heat fluxes at the higher northern latitudes of the Nordic seas during the last interglacial period. The cooling which terminated the interglacial period occurred before the increase in the volume of the ice. The high latitudes reacted to the climatic changes before other latitudes of the Northern Hemisphere. The changes in the sea surface temperature occurs in correspondence to the changes in the values of the benthic delta-oxygen isotopes.

Oceanic evidence for coherent fluctuations in Fennoscandian and Laurentide ice sheets on millennium timescales
Article Abstract:
The cooling activity and the discharge of icebergs from a sediment core present in the Norwegian Sea is similar to that seen in the Heinrich events of the last glacial age. The changes in the climate of the Norwegian Sea are in phase with the air temperature over Greenland. Thus the effects of the fluctuations in the heat fluxes of the North Atlantic affect Greenland. The timescale of the changes in the Fennoscandian and Laurentide ice sheets with the transport of heat from the ocean and land is shorter than that of the Milankovitch orbital cycles.

Frozen-bed Fennoscandian and Laurentide ice sheets during the Last Glacial Maximum
Article Abstract:
It is shown that the occurrence of ribbed moraines in modern landscapes can be utilized to determine former spatial distribution of frozen and thawed bed conditions. It is argued that the ribbed moraines developed after brittle fracture of subglacial sediments, caused by stress at the boundary between frozen and thawed bed conditions.
