Dear Colleagues,
Appologies for cross posting. We encourage you to consider submitting an abstract to the "Bedrock breakdown" session at the AGU Fall Meeting in December. Feel free to share this with students and collaborators who may also be interested.
Invited speakers include Sue Brantley (Penn State) and Emma Lodes (Arizona State University).
EP007: Bedrock breakdown: The role of weathering in the evolution and function of the critical zone
Session description:
The breakdown of bedrock due to chemical and physical weathering processes creates and opens fractures and pores. This void space affects water movement and storage within hillslopes, making it vital to many hydrologic and ecological processes. Weathering also affects rock strength and hillslope sediment grain-size, which in turn control rates of erosion, sediment transport, and landscape evolution.
We seek contributions that use observational, experimental, and modeling techniques to quantify the fundamental controls on weathering in the critical zone (CZ) and the consequences of weathering for geomorphic, hydrologic, and ecological processes. Because CZ science is transdisciplinary, contributions will span diverse scales and methods, from mineral-scale measurements of fracturing and chemical alteration, to hillslope-scale geophysical measurements of CZ structure, to modeling and remote sensing of landscape-scale CZ processes. We especially encourage contributions that span disciplines and lead to a transformative understanding of CZ processes.
The deadline for submission is Wednesday, July 31st.
We are looking forward to seeing everyone at AGU this year!
Russell Callahan, David Litwin, and Nancy Weinheimer
