Bentley, M.J., and Anderson, J.B., 1998,
Glacial and Marine Geological Evidence for the Extent of
Grounded Ice in the Weddell Sea - Antarctic Peninsula Region During the Last
Glacial Maximum: Antarctic Science, v. 10, (3), p. 307 - 323Berkman, P.A. and Ku, T. - H.
Sea level dropped during the last
glacial maximum, but there was no ice sheet in Siberia, so the surface was exposed to the really cold atmosphere, and the
ground froze to a depth of ~ 1.5 km.
