You are invited to submit an abstract to the following special session
at this year's American Geophysical Union (AGU) Fall Meeting:

PP 21: Examining Late Quaternary Linkages Between Oceanographic,
Terrestrial, and Cryospheric Dynamics in the Northeastern Pacific and
Gulf of Alaska Regions

Session Description:
On a global scale, models predict the sensitivity of North American
climate to atmospheric-oceanic dynamics in the north Pacific associated
with potentially interrelated modes of climate variability, including
the Pacific Decadal Oscillation, the Pacific-North American Pattern, El
Nino/Southern Oscillation, and the Arctic Oscillation. The northeast
Pacific and Gulf of Alaska region is an ideal area to examine the impact
of these modes of variability on oceanographic, terrestrial, and
cryospheric dynamics. Within a constrained geographic region at the end
of the north Pacific storm track, these three interlinked systems
respond to large-scale climate forcing, but the transfer of this climate
signal between the three systems over Late Quaternary time scales
remains poorly understood. Establishing timing and linkages between
these systems could help in addressing a major challenge in Quaternary
paleoclimatology regarding the synchroneity and global extent of
large-scale climate events since the Last Glacial Maximum. With these
considerations, organizers propose a session to explore how Late
Quaternary modes of climate variability and global climate events have
impacted regional ocean processes, landscape change, and cryospheric
dynamics and how each system responds to contemporaneous forcing. In
particular, organizers invite those scientists who utilize marine and
lacustrine sediments, ice cores, alluvial, and other terrestrial
deposits to examine climate change in the northeast Pacific/Gulf of
Alaska region over the Late Quaternary. Organizers also seek researchers
exploring the dynamics of how modern climate patterns in the region
affect precipitation patterns and ice dynamics and how signals of the
evolving glacial systems are propagated into and recorded by lacustrine
and marine sediments. This session is timely as a number of tree-ring
studies, lacustrine and marine sedimentary records, and ice core
glacichemical time series have recently been generated that provide
seasonally-to-decadally resolved proxy records of atmospheric pressure,
circulation patterns, temperature, precipitation, glacial dynamics,
runoff, and ocean temperature and salinity.
