The American Geophysical Union (AGU) is currently accepting abstract
submissions for the 2013 Fall Meeting. The meeting will be held 9-13
December 2013 in San Francisco, California. Conveners of the following
sessions invite presentations from the Arctic community:

ED020 - From Pole to Pole: Experiences Educating About the Polar Regions
Global efforts to raise awareness and literacy about the Arctic and
Antarctic continue to grow, with new events and activities stemming out
of initiatives such as the 2007-2008 International Polar Year, the
Association of Polar Early Career Scientists, and Polar Educators
International. This session provides a platform for educators and
scientists to share perspectives, experiences, and resources used in
communicating the scientific, social, and political issues of the polar
regions. An aim of this session is to foster new collaborations, inspire
ideas, and improve the effectiveness and reach of these globally diverse
educational efforts.

C009 - Geophysical and Atmospheric Data Streams from Polar
Observatories, User Facilities, Data Collection Networks, and Field
Campaigns
This session is intended for presentations that document geophysical and
atmospheric data streams available from scientific facilities in Polar
Regions. The session will be open to presentations about existing or
planned deployments of fixed or mobile facilities, including aerial
platforms, manned or unmanned. Existing user facilities currently
provide data to the research community from long-term baseline
instruments and from those deployed for episodic campaigns. This session
will provide a forum for introduction and discussion of facilities and
data available to the international polar research community for study
of geophysical and atmospheric processes.

OS013 - Marginal Ice Zone Dynamics
Marginal ice zone (MIZ)-type conditions are becoming more prevalent in
the Arctic with the onset of climate change. The larger regions of
partially ice-covered ocean have ushered in a new era of human
activities, e.g. offshore engineering activities, in the Arctic Ocean.
Predictions of ice properties like concentration, thickness, floe sizes
and drift, as well as wave activity and ocean currents, are urgently
needed in order to assist operations to be carried out more safely. We
invite presentations related to any aspect of MIZ dynamics. Topics could
include: operational wave and ocean modeling in the MIZ; wave-ice,
ocean-ice, and air-ice interactions; ice drift, rheology and
thermodynamics in the MIZ; and modeling and observations of the floe
size distribution.

C007 - Factors Driving Variability in Seasonal Sea Ice Extent and
Thickness in the Arctic and Antarctica
A great deal of research has focused on the drivers of past/present
Arctic summer sea ice loss, but there has been less attention to sea-ice
patterns in other seasons, to sea-ice variability in Antarctica, and to
model projections for future sea-ice changes at both poles. This session
will explore the drivers that affect variability in sea-ice extent and
thickness at both poles, including next steps to improve future
projections of seasonal sea-ice changes. The session also invites
abstracts that explore the possible consequences of these changes for
other components of the polar system (e.g., biogeochemical cycling, food
webs, and circulation systems).

B052 - Observations and Model Requirements for Understanding Drivers of
Disturbance Processes in Arctic and Boreal Terrestrial Ecosystems
Current-generation Earth System Models do not well-represent key
ecosystem processes in Arctic and Boreal ecosystems. A range of
disturbance processes across the press (e.g. permafrost thaw) to pulse
(e.g. fire, insects, and thermokarst) spectrum are causing widespread
changes to ecosystem function in these ecosystems. Organizing existing
and new data collections within a synthesis framework will facilitate
incorporating these processes and their feedbacks in modeling
applications and for understanding disturbance for land management. Our
session invites papers involving observational, experimental, remote
sensing and modeling studies characterizing these disturbance processes
and their impacts on the key components of Arctic-Boreal system.

B048 - Natural Wetlands and the Global Methane Cycle
Natural wetlands are a major, climate-sensitive methane (CH4) source.
Uncertainties in wetland CH4 dynamics derive from heterogeneity in
vegetation, hydrologic regime, and CH4 production, oxidation, transport
and emission. Understanding wetland ecosystems, distribution and CH4
dynamics, from field to global scales, is crucial to predicting
biogeochemical and distributional dynamics under past, present and
future climates. We invite studies on: processes of CH4 production,
oxidation and emission; remote sensing of hydrologic dynamics and
vegetation characterization; modeling of wetland distributions and CH4
dynamics; and role of wetlands in the global methane cycle under past,
current and future climates.

B050 - New Mechanisms, Feedbacks, and Approaches for Improving
Predictions of the Global Carbon Cycle in Earth System Models
Predictions of future atmospheric CO2 concentrations are influenced by
global carbon and nutrient cycles, climate interactions, and feedbacks.
Relevant processes operate at different spatial and temporal scales,
vary across marine and terrestrial ecosystems and remain uncertain.
Moreover, feedbacks may be altered by anthropogenic disturbance agents,
including tropospheric O_3 , acceleration of the N and H_2 O cycles,
eutrophication, and land cover/use changes. This session focuses on
integrated understanding of feedback mechanisms, structure and function
of critical and vulnerable ecosystems, human activities, and approaches
for evaluating and benchmarking Earth System Models.

The abstract submission deadline for all sessions is Tuesday, 6 August
2013 at 11:59 p.m. Eastern Daylight Time. The first author must be a
current 2013 AGU member. Details on abstract submission are available at:
