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.
