  1. GC03 - Greening of the Arctic

Organizers of Session GC03, "Greening of the Arctic," 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.

Rapid arctic vegetation change has been attributed to interactions of
many factors including warmer land temperatures, changing permafrost and
snow regimes, greater amounts of shrubs, long-term vegetation
succession, greater cover of plants, and changing disturbance and
nutrient regimes. The intent of this session is to summarize and
synthesize the information from long-term and large-area studies of
arctic vegetation change. Papers describing plant-community, biomass,
and remotely sensed spectral properties along long transects and large
regions, as well as more focused long-term studies involving
dendrochronology of shrubs, repeat-photos, experiments, and modeling are
welcome.

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.

  1. GC10 - Biogeochemical Responses to a Changing Arctic

Organizers of Session GC10, "Biogeochemical Responses to a Changing
Arctic," 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.

The arctic is experiencing rapid increases in temperature and changes in
precipitation with expected direct and indirect consequences for
biogeochemical and biophysical processes. Changes in temperature and net
precipitation are likely to influence growing season length, the
seasonality of biogeochemical processes, permafrost dynamics, and fire
regimes. These linkages are poorly understood, but are clearly important
in understanding how the arctic will influence and respond to future
climate change. This interdisciplinary session focuses on understanding
how the biogeochemistry of arctic vegetation, streams, lakes, and soils
will respond to climate change. Contributions focusing on direct and
indirect effects are encouraged.

The abstract submission deadline for this and all other sessions is

an abstract, you must enter the first author's current AGU member ID and

  1. GC23 - The Future of Polar Science: The Path Beyond the IPY

The National Research Council's Polar Research Board (PRB), organizers
of Session GC23, "The Future of Polar Science: The Path Beyond the IPY,"
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.

The polar regions are at the forefront of modern environmental change,
currently experiencing the largest and fastest changes in climate and
environment. This session, convened by the PRB, which served as the U.S.
National Committee for IPY, will explore the future of arctic and
Antarctic science beyond International Polar Year 2007-08.

Presentations will look at where we are now and what is next in
understanding physical and biological systems, the role of the poles in
the evolution of global systems, social changes in northern regions,
education and outreach, and the interface between science and policy.
Presentations from students and multiple disciplines are encouraged.

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.

  1. GC25 - Decadal-scale Arctic Climate Variability: Observations and
    Modeling

Organizers of Session GC25, "Decadal-scale Arctic Climate Variability:
Observations and Modeling," 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.

Climate change in the Arctic is of special interest due to sea ice area
and thickness reduction, temperature change amplification, permafrost
reduction, and an accelerated melting of the Greenland ice sheet. These
changes are expected to have a profound effect on the regional
environment, atmospheric and ocean circulation, and climate around the
world. The Arctic presents unique challenges with the interaction
between anthropogenic warming and strong decadal-scale climate
variability. Studies based on the instrumental data and on paleo-proxies
of decadal-scale climate indices as well as model simulations of the
past and projections for the future arctic climate are welcome in this
session.

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.
