B045 - Natural Wetlands: Distribution, Methane Dynamics and Role
in the Global Methane Cycle

Organizers of Session B045, "Natural Wetlands: Distribution, Methane
Dynamics and Role in the Global Methane Cycle," announce a call for
abstracts. The session will be convened at the American Geophysical
Union (AGU) Fall Meeting, 3-7 December 2012 in San Francisco,
California.

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 CH4 cycle under past,
current and future climates.

The abstract submission deadline for this and all other sessions is
Wednesday, 8 August 2012 at 11:59 p.m. Eastern Daylight Time. To submit
an abstract, you must either be a current 2012 AGU member, or have the
ID of your AGU member sponsor. For further details on the abstract
submission process, please go to: http://agu-fm12.abstractcentral.com/.

B046 - New Mechanisms, Feedbacks, and Approaches for Improving
Predictions of the Global Carbon Cycle in Earth System Models

Organizers of B046, "New Mechanisms, Feedbacks, and Approaches for
Improving Predictions of the Global Carbon Cycle in Earth System
Models," announce a call for abstracts. The session will be convened at
the American Geophysical Union (AGU) Fall Meeting, 3-7 December 2012 in
San Francisco, California.

Predictions of future atmospheric CO2 concentrations are influenced by
global carbon and nutrient cycles (e.g., N & P) and climate interactions
and feedbacks. These operate at different spatial and temporal scales,
vary across ocean and terrestrial biomes, and are highly uncertain.
Moreover, feedbacks may be altered by anthropogenic disturbance agents,
including tropospheric ozone, acceleration of the N cycle,
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 evaluation and benchmarking of Earth System Models.

C003 - Arctic and Antarctic Sea Ice Processes and Properties

Organizers of Session C003, "Arctic and Antarctic Sea Ice Processes and
Properties," announce a call for abstracts. The session will be convened
at the American Geophysical Union (AGU) Fall Meeting, 3-7 December 2012
in San Francisco, California.

Recent years have seen a dramatic reduction in the extent and thickness
of Arctic Ocean sea ice and redistribution and modest increases in ice
extent in the Southern Ocean. The inability of climate models to predict
these changes suggests the need for more accurate representation of sea
ice processes in models. Ongoing changes in sea ice physical properties
are also affecting the biogeochemistry of the polar seas. This session
examines sea ice and its snow cover, and the interactions and feedbacks
with the atmosphere and ocean. We welcome remote sensing, field,
laboratory, and modeling studies of the processes that affect the
properties of arctic and Antarctic sea ice.

CO15 - Geophysical Characterization of Permafrost Systems

Organizers of Session CO15, "Geophysical Characterization of Permafrost
Systems," announce a call for abstracts. The session will be convened at
the American Geophysical Union (AGU) Fall Meeting, 3-7 December 2012 in
San Francisco, California.

The complexity of permafrost dynamics and its critical impact on climate
feedbacks warrant continued development of advanced characterization and
monitoring approaches. Geophysical methods can provide information about
subsurface physical, hydrological, thermal and geochemical variations
needed to understand these feedbacks in a non-invasive manner and with a
spatial coverage and data density that cannot be achieved using point
measurements. This session seeks novel examples that use geophysical
data to characterize and monitor permafrost systems through integrated
inversion of multiple types of data at various scales, and that
investigate physical property relationships between geophysical and
permafrost-related properties of interest.

GC004 - Barrow, Alaska: Decades of Iconic Data Sets as a
Cornerstone of Arctic Observing

Organizers of Session GC004, "Barrow, Alaska: Decades of Iconic Data
Sets as a Cornerstone of Arctic Observing," announce a call for
abstracts. The session will be convened at the American Geophysical
Union (AGU) Fall Meeting, 3-7 December 2012 in San Francisco,
California.

Barrow has served as a base for all aspects of arctic research. Local,
traditional knowledge among the resident Inupiat extends back many
generations. Thus, Barrow is a potential flagship site for the U.S.
Interagency Arctic Observing Network (IAON) and international programs
in Alaska. This session focuses on Barrow region data sets of high
quality, long duration, and high scientific and stakeholder relevance.
Examples include climate stations, river and sea ice breakup dates,
plant community changes or permafrost borehole temperatures. The aims
are to showcase such iconic data and help create a framework for their
sustainment and application within IAON to address key questions about a
changing Arctic.
