The positions of ice dispersal centers and of ice cap limits, both on land and on the sea bed, have been located fairly precisely by means of an analysis of marginal features produced by the last glaciation of Northern Eurasia, using in particular new data on the geomorphology of the beds of the Barents and Kara seas. The configuration of the various ice caps was then reconstructed on the basis of both glaciological and geomorphological data. Of particular interest is the conclusion that both the Barents and Kara seas were covered by a number of independent ice caps, contiguous to varying degrees and for verying periods, rather than by one massive ice cap, as had been earlier proposed.
