Purpose
To characterize seismic facies for interpreting past glacier behavior,
especially during the last glacial maximum. Glacier Bay is the site of
the best documented major marine deglaciation in the world and allows
comparison between glacier terminus stability with changing climate and
marine conditions. Upper Yakutat Bay contains deposits produced by the
surge of the Hubbard Glacier in 1986 and the subsequent outburst flood
from Russell Fjord. Historical records of glacier terminus positions
provide a datum with which the history of this marine glacial system
can be determined from seismic and sedimentary facies.
