Dear colleagues, We encourage you to submit an abstract to the AGU session, "Iron: A Catalyst for Biogeochemical Processes in Terrestrial Ecosystems" (Session ID #2321).
Confirmed Invited Presenters: Oliver Chadwick (University of California, Santa Barbara) Scott Fendorf (Stanford University) Eric Roden (University of Wisconsin, Madison) Whendee Silver (University of California, Berkeley) Session Description: Changes in the redox state of iron can be coupled to biogeochemical cycling of other elements, such as carbon, nitrogen, and phosphorus, and thus, potentially play an important role in regulating ecosystem nutrient availability and greenhouse gas production. Until recently, iron redox cycling in terrestrial ecosystems was under-appreciated due to the misconception that reducing conditions rarely occur in upland soils. However, evidence is mounting that iron can be an important catalyst for both biotic and abiotic soil biogeochemical processes. We need a better understanding of the drivers of iron-coupled biogeochemical processes to predict when and where these processes could be relevant on the ecosystem scale and how process rates may change in response to global changes. In this session, we will explore microbial, geochemical, and pedogenic aspects of iron redox cycling and its coupling to other biogeochemical cycles. Abstract submissions are due on August 6, 2014 at 23:59 EDT at the following website: http://fallmeeting.agu.org/2014/scientific-program/ We hope you can join us!
