Dear Friends, During this year's American Geophysical Union meeting in San Francisco, California, on 9-13 December, Jason Gulley, Matt Covington, and Corinne Wong will host an important session that may interest you. The description of their session is below. For more information and to submit an abstract (deadline is 6 August 2013), visit http://fallmeeting.agu.org/2013/.
Critical Zone Processes in Carbonates: Carbonate rocks cover 20% of Earth's ice-free land and are modified by hydrological, biological and geochemical processes in the critical zone. Congruent dissolution and high solubility of carbonate rocks should lead to Critical Zone processes that are different than those occurring in siliciclastic rocks, which are dominated by incongruent weathering. Caves, an extreme endmember of critical zone processes in carbonates, provide efficient pathways for oxygen and carbon into the subsurface, resulting in complex subsurface chemical and gas gradients that do not occur in siliciclastic systems. This session solicits abstracts dealing hydrological, biological or geochemical processes operating in the carbonate critical zone, broadly defined. Please distribute this message to anyone you think may be interested. Thank you, George ******************** George Veni, Ph.D. Executive Director National Cave and Karst Research Institute 400-1 Cascades Avenue Carlsbad, New Mexico 88220-6215 USA Office: 575-887-5517 Mobile: 210-863-5919 Fax: 575-887-5523 [email protected]<mailto:[email protected]> www.nckri.org<http://www.nckri.org>
