286 EARTH'S SHIFTING CRUST
Arctic and the North Atlantic. A glance at the globe will
make this clear.
Beginning 50,000 years ago, and lasting for about 5,000
years, there was, according to the Soviet scientists, a brief
warm spell in the Arctic Ocean:
. . . The bottom sediments became finer; argillaceous and highly
argillaceous oozes began to be deposited,
of a brown or here and
there dark brown color, with increased contents of iron oxides, man-
ganese, and foraminiferous micro-fauna (364:9).
This warm period may reflect the movement of the crust
that resulted in withdrawal of the pole from Greenland and
its shift toward Hudson Bay. It is followed, however, by a
cold period in the Arctic from 45,000 to 28-32,000 years ago.
This following cold period is explained, according to our
theory, by the beginning of the subsidence of the land bridge,
which may have opened a water connection between the two
oceans. The pole was at this time still near the Atlantic, and
very cold Atlantic water was thus able to pour
into the
warmer Arctic. The subsidence of the land bridge as the pole
moved away is, of course, a corollary of our theory. Such a
subsidence in any area moving away from a pole would positively
have to occur, unless counteracted locally by the relocation
at particular points under the crust of lighter rock de-
tached from the underside of the crust elsewhere.
Following this cold period in the Arctic, we come to a
most remarkable change, one which, in my opinion, provides
an unusually impressive confirmation of our assumption of
the location of the Hudson Bay region at the pole. About
28-32,000 years ago, a really warm period began in the
Arctic, and lasted until 18,000 to 20,000 years ago. The
Soviet scientists have found that during this period there was
a rich development of temperate-type microfauna in the
Arctic, though their explanation is very
different from ours:
. . . The luxuriant development of a foraminiferal fauna of North
Atlantic type testifies that during this period warm Atlantic waters
were invading the Arctic Basin on a broad front; that is, communication
between the Arctic Basin and the Atlantic Ocean, which had
