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.

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/.

B069 - Vulnerability of Permafrost Carbon to Climate Change

Organizers of Session B069, "Vulnerability of Permafrost Carbon to
Climate Change," 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.

Permafrost zone soils contain 1670 Pg of carbon (C). Permafrost
degradation can change ecosystem C storage by enhancing microbial
activity and ecosystem respiration, but can also stimulate plant growth
and increase C stored in vegetation and surface soil. This session
invites papers that examine factors causing losses and gains in
ecosystem C storage that relate to the question: What is the magnitude,
timing and form of C release from permafrost zone ecosystems to the
atmosphere in a changing climate? Papers may address any aspect of this
topic from microbial communities to the global scale, using a range of
measurements or modeling to detect and forecast permafrost thaw and the
influence on the C cycle and future climate.

C016 - Glacial Melting: Connecting Hydrological, Geochemical, and
Microbiological Processes in Glacial Environments

Organizers of Session C016, "Glacial Melting: Connecting Hydrological,
Geochemical, and Microbiological Processes in Glacial Environments,"
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.

Increasing melting of the cryosphere affects the terrestrial and marine
environment through glacial/periglacial processes and release of water
and solutes to the ocean. This session studies the connection of
hydrological, microbial, and geochemical processes of glacier and ice
sheets and their contribution to fluxes of water and nutrient to the
ocean. Organizers invite papers which study interaction of these
processes. Field studies as well as experimental and modeling studies
are welcome. Session organizers are especially interested in studies
that link microbial and geochemical processes to lithology and climate,
and those that explore connection between surface melting and subglacial
processes.

C017 - Glacier, Ice Cap, and Ice Sheet Hydrology: Storage,
Transport, and Impacts

Organizers of Session C017, "Glacier, Ice Cap, and Ice Sheet Hydrology:
Storage, Transport, and Impacts," 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 hydrologic system of glaciers, ice caps and ice sheets is
intrinsically linked to their responses to climate variability. This
system may take a variety of forms, and include firn layers, supra- and
sub- glacial lakes, streams, transport pathways through moulins,
crevasses, and other conduits. Organizers invite contributions examining
development, functioning, and importance of storages and transport
pathways on, under and within the ice sheet, and interactions between
this system and ice thermal state, dynamics, and water and energy
exchange. This includes movement of water between sub-glacial lakes,
supra-glacial lake storage, and interactions with seawater in marine
environments.
