Dear Carbon Cycling Scientists:
We would like to call your attention to a soil carbon session sponsored by
the Biogeosciences Section at the American Geophysical Union (AGU) meeting
in San Francisco, CA, this winter, December 14-19, 2008. Talks utilizing 14C and 13C
methodologies to assess C cycling dynamics at multiple scales are encouraged.
Session number: B21
"Toward Large Scale Assessments of Soil Carbon Turnover and Vulnerability:
Measures, Models, and Networks"
Soil is a crucial natural resource and soil carbon is an integral component
of soil structure and function. Although the global stock of soil carbon is
immense, it is not static: about 120 Pg of carbon moves annually between
soil and the atmosphere and vegetation. Soil carbon may thus play a
singular but uncertain role in climate forcing during the coming decades,
with significant net losses contributing to positive feedbacks, or
significant sequestration helping to mitigate climate forcing. The loss of
soil carbon or disruption of its cycling may also impair the ecosystem
services it provides, with consequent negative impacts on society. Given
the critical role that soil carbon plays in the climate cycle and
ecosystems services globally, there is a strong need to conduct large
scale, spatially explicit assessments of soil carbon turnover and
vulnerability. Recent advances in measurement technologies, statistical
applications, modeling approaches, and geographic information systems have
made it possible to develop stand-to-landscape scale information in support
of carbon sequestration decisions by both land managers and policy makers.
This session invites researchers to discuss measurement, modeling, and
networking of soil carbon turnover and vulnerability studies.
Abstracts due: 10 September 2008, 2359 UT (Universal Time).
