by the ionium method. These cores provide impressive confirmation
of the situation of the pole in North America dur-
ing the Wisconsin glaciation, and, in addition, they furnish
evidence of the approximate date of its migration to the
Hudson Bay region from its previous position.
The Soviet scientists were much impressed by their dis-
covery that in the comparatively short period
of the last
50,000 years there have been no less than six major changes
of climate in the Arctic Ocean. They did not find it easy to
explain all these changes. They may all be explained, how-
ever, by the hypothesis of two displacements
of the earth's
crust.
The period begins with a very cold phase. Since the cores
go back only 50,000 years, we do not know when the cold
period began. The scientists remark:
It seems that in the period in question, a considerable part of the
Arctic shelf was dry; ther was no, or almost no, communication with
the Atlantic. The climate was cold (364:9).
According to the principles already set forth (Chapter IV),
a pole in southern Greenland might be expected to have
coincided with higher elevation of that general region, in-
cluding the adjacent sea bottoms. The continental shelves
in that part of the Arctic Ocean facing toward Scandinavia
might well have been raised above sea level. There might
well have been a land connection between Greenland and
Iceland, and even across the narrow North Atlantic to Scan-
dinavia. The Soviet scientists themselves strongly suggest
that this land connection must have existed; nor are they
alone in their suggestion. Years ago Humphreys advanced the
idea. More recently Malaise has produced much new evi-
dence for it (2 91 a). Thus it is evident that our theory has
started out pretty well, by explaining why
there was little
communication between the two oceans. The interruption,
however, was not simply the result of land masses in the
North Atlantic. It could also have been the result of having
a polar area lying right across the connections between the
