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.
