Dear all,
Please take note of this AGU session on
the deep critical zone. We use "deep" to loosely refer to all aspects
of the subsurface but especially welcome contributions that employ drilling and geophysical imaging to explore incipient weathering, ecological colonization, and/or connections between surface and subsurface processes. We expect to host contributions from all critical zone disciplines, including geobiology, hydrology, geochemistry, geomorphology and near-surface geophysics.
If this sounds like a fit with your work, please consider submitting an abstract.
Abstract deadline: August 8th.
Official session description follows:
EP032: The Deep Critical Zone and the Inception of Surface Processes
Surface
processes begin deep within the critical zone, often below the soil,
where alterations by chemical, physical and biological processes prepare
rock for incorporation into life-sustaining regolith. To the extent
that surface processes influence as well as depend on deep weathering,
there should be exciting feedbacks among landscape evolution,
biogeochemical cycling, hydrologic processes and the inception of
weathering at depth. We seek contributions that explore linkages between
the surface and subsurface for improved understanding of critical zone
processes and feedbacks. Interdisciplinary studies that feature
drilling, sampling, modeling, and/or geophysical imaging of the deep
critical zone are especially encouraged.
