Organizers of Session U09, "Response of the Arctic Landscape to a
Warming Climate," announce a call for abstracts. The session will be
convened at the American Geophysical Union (AGU) Fall Meeting, 14-18
December 2009, in San Francisco, California.

Increases in northern air temperatures are substantially modifying the
arctic landscape. Responses to this changing climate include
intensification of the hydrologic cycle, permafrost thaw, changes in
vegetation pattern and diversity, thermokarst formation, and modified
cycling of carbon, nitrogen, and phosphorous. The questions we seek to
address cut across several geosciences fields:

- How much carbon will potentially be released due to permafrost
degradation?
- To what degree are surface processes accelerating?
- How do terrestrial changes influence aquatic ecosystems?
- What promising new approaches are available to document the rate
and extent of landscape change in the Arctic?
- What do model projections suggest about possible interactions and
feedbacks in water and nutrient cycles?

Organizers seek a broad set of presentations contributing to enhanced
documentation and investigation of the feedbacks between arctic climate
change and landscape response. Please note that this is a Union session;
as such, organizers welcome a broad range of perspectives relating to
the topic (e.g., permafrost warming and degradation, thermokarst,
terrestrial and aquatic ecological feedbacks, biogeochemical cycling,
geomorphological responses, hydrologic responses, and coastal erosion).

The abstract submission deadline for this and all other sessions is
Thursday, 3 September 2009, 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-fm09.abstractcentral.com/.
