B24 - Cryospheric Biogeochemistry - Microbially Mediated
Processes Within Ice, Water, and Till

Organizers of Session B24, "Cryospheric Biogeochemistry - Microbially
Mediated Processes Within Ice, Water, and Till," announce a call for
abstracts. The session will be convened at the American Geophysical
Union (AGU) Fall Meeting, 13-17 December 2010 in San Francisco,
California.

There is increasing realization that microbial processes occur on the
surface, within, and beneath glaciers and ice sheets. Cryoconite holes
are oases of biological activity on glacier surfaces, microorganisms
survive the journey from surface snow through to the bed of the
Antarctic and Greenland Ice Sheets, and most subglacial aquatic
environments are colonized by microorganisms, which span the range of
REDOX conditions from fully oxygenated to fully anoxic. The
state-of-the-science revolves around how microbial processes map onto
the diverse range of cryospheric aquatic environments, from ice veins to
channels and lakes, and the impact that they have on glacial water and
gas geochemistry.

The abstract submission deadline for this and all other sessions is
Thursday, 2 September 2010 at 11:59 pm Eastern Daylight Time. To submit
an abstract, you must enter the first author's current AGU member ID and
password at: http://agu-fm10.abstractcentral.com/index.jsp.

B25 - Biogeochemical Cycling in Glacial Ecosystems

Organizers of Session B25, "Biogeochemical Cycling in Glacial
Ecosystems," announce a call for abstracts. The session will be convened
at the American Geophysical Union (AGU) Fall Meeting, 13-17 December
2010 in San Francisco, California.

Despite the fact that glacial ecosystems in many regions are being
rapidly altered by climate change, relatively little is known about
their biogeochemical dynamics. Organizers seek contributions that
address biogeochemical cycling along the glacial continuum; from glacial
ice to sub-glacial and recently deglaciated soils to pro-glacial streams
and rivers. In particular, organizers are interested in research that
provides new insights into the biogeochemical functioning of glacier
ecosystems and how they may be impacted by continued climate warming.
This session is inteded to bring together research on terrestrial,
glacial, and aquatic biogeochemistry within glacial ecosystems.

B63 - The Dynamics of Trace Gas Exchange in Northern Ecosystems
During Spring Thaw and Fall Freeze

Organizers of Session B63, "The Dynamics of Trace Gas Exchange in
Northern Ecosystems During Spring Thaw and Fall Freeze," announce a call
for abstracts. The session will be convened at the American Geophysical
Union (AGU) Fall Meeting, 13-17 December 2010 in San Francisco,
California.

There have been reports of spring pulses of CO2 and CH4 from lakes and
bogs as well as large amounts of CH4 released in the fall from
permafrost mires. The elevated emissions are temporally constrained and
are the result of unique combinations of biological and physical
drivers. A session is needed to improve community understanding of the
magnitudes and the controls in order to better constrain the dynamics of
the C balance of northern ecosystems in a changing climate. Organizers
encourage contributors to focus contributions that may extract data from
multi-year data sets to look at specific dynamics during the shoulder
seasons.

C06 - Advances in Glacier Seismology

Organizers of Session C06, "Advances in Glacier Seismology," announce a
call for abstracts. The session will be convened at the American
Geophysical Union (AGU) Fall Meeting, 13-17 December 2010 in San
Francisco, California.

During the past decade seismology has rapidly evolved as a tool for
investigating and monitoring dynamic glaciological processes. Seismic
observations have given insights into subglacial hydrology and outburst
floods, basal motion, subglacial bed properties, iceberg calving and
crevassing, glaciogenic ocean waves, ice shelf flexure, and ice
melange/sikkusak behavior. Although the full utility of glacier
seismology is not yet known, it is clear that seismology will play an
important role in glaciology in the coming years. Organizers solicit
submissions on any topic related to glacier seismology, including both
active- and passive-source seismology.

C12 - Ice Cores, Climate, and Ice Sheets: New Frontiers

Organizers of Session C12, "Ice Cores, Climate, and Ice Sheets: New
Frontiers," announce a call for abstracts. The session will be convened
at the American Geophysical Union (AGU) Fall Meeting, 13-17 December
2010 in San Francisco, California.

Ice cores from the Northern and Southern Ice Sheets and Ice Caps reveal
a wealth of information about past climates and environments. New ice
core measurements and new applications of established measurements are
quickly expanding the information we can infer about climate, greenhouse
gases, and the evolution of the ice sheets and their impact on sea
level. This session will focus on new frontiers both in terms of new ice
cores and new methods of observations. Comparison of ice core records
adds a further dimension to the information that can be gained from ice
core studies and is encouraged, as is research leading to the
reconstruction of the evolution of the ice masses including results from
ice flow models and radio echo sounding.

C25 - Scientific Inquiry Using Cryospheric Climate Data Records

Organizers of Session C25, "Scientific Inquiry Using Cryospheric Climate
Data Records," announce a call for abstracts. The session will be
convened at the American Geophysical Union (AGU) Fall Meeting, 13-17
December 2010 in San Francisco, California.

This session will focus on the development and use of cryospheric
climate date records (CDRs) for scientific inquiry during the satellite
era. CDRs represent time series of measurements of sufficient length,
consistency, and continuity to determine climate variability and change.
Contributions are encouraged covering the full spectrum of CDR
development and use, including initial formulation of algorithms,
validation, error assessment, and use for scientific inquiry. This
session will bring together efforts in the development and use of CDRs
over cryospheric regions covering oceans, ice, and terrestrial surfaces,
including but not limited to snow cover, sea and land ice, melt onset,
and ice temperature.
