  1. C006 - CryoSat-2: Science and Validation

Organizers of Session C006, "CryoSat-2: Science and Validation,"
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 European Space Agency (ESA) CryoSat mission is dedicated to precise
monitoring of changes in the thickness of ice floating in the polar
oceans and variations in the thickness of the Antarctic and Greenland
ice sheets. It is also able to provide measurements over continental
glaciers and the global oceans. This session is a forum to assess the
technical performance and early scientific results of the CryoSat
mission. Organizers welcome abstracts on all aspects of satellite
geodesy, including ice sheets, glaciers, sea ice, marine gravity, and
oceanography, in addition to abstracts that describe the instrument and
platform calibration and in-situ validation of geophysical products
derived from CryoSat-2 data.

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/.

  1. C040 - The Ice Core Record of Carbon Cycle History and Processes

Organizers of C040, "The Ice Core Record of Carbon Cycle History and
Processes," 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.

Carbon compounds of many types are preserved in ice cores and provide a
unique window into the functioning of the carbon cycle. New analytical
developments have increased the number of species measured and the
amount of data generated. Continuous ultra-high-resolution gas records
are revealing new modes of greenhouse gas variability, and stable and
radio isotopic measurements are expanding our mechanistic understanding
of global carbon cycle processes. Black carbon and other new tracers are
increasing our understanding of past biomass burning and the impact of
black carbon on snow albedo and ice sheet retreat. This session welcomes
data and modeling contributions related to these developments on any
temporal or spatial scale.

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

  1. EP035 - Thermal Control on Weathering, Erosion, and Landscape
    Evolution

Organizers of Session EP035, "Thermal Control on Weathering, Erosion,
and Landscape Evolution," 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.

Many physical processes that break rock, form soils, and transport
material down slope are temperature and water dependent. Some processes
require a change in phase while others do not, but all vary in time and
space with Earth's climate. Thermal control exists in diverse landscapes
- from high alpine catchments to low-lying arctic permafrost to arid
regions. This session examines the influence of temperature on
weathering, erosion and landscape evolution over a wide range of
timescales. Organizers solicit presentations that examine thermal
modulation of geomorphic process and form, including field-based
studies, process and landscape scale numerical or physical modeling
studies, and experimental investigations.

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/.

  1. GC003 - Altered Nutrient Cycling in High-Latitude Ecosystems

Organizers of Session GC003, "Altered Nutrient Cycling in High-Latitude
Ecosystems," 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.

Despite strong nutrient limitation at high latitudes, less attention is
paid to climate change impacts on nutrient cycling than to direct
effects on carbon cycling. In addition to a potential source of
nutrients with permafrost thaw, climate change may alter disturbance
regimes (i.e. fire), hydrology (i.e. water tables), and vegetation
communities (i.e. shrub expansion). These factors influence nutrient
inputs, cycling, and transport. In this session, organizers propose to
explore how changing climate alters nutrient dynamics in
permafrost-dominated ecosystems. They welcome presentations on the
cycling of N, P, and other nutrients, especially those on disturbance
effects, terrestrial-aquatic linkages, and growing season controls on
productivity.

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/.
