Soil SWIRL at the AGU 2014 fall meeting
To continue to promote interdisciplinary collaboration at Fall Meeting, the 2013 AGU Program Committee identified the SWIRL theme "Global Soils"
Soils are part of the Critical Zone, and are both responders and drivers of the most critical environmental changes facing the earth during the Anthropocene. Controls on soil organic matter and C-cycling processes have dominated these discipline-specific sessions. The soils SWIRL accounts for all aspects of the complexity of the soil system including erosion, dust production, soils in water transport and chemistry, isotopic analyses, pedogenic processes affected by volcanism, physical, chemical and biological composition, fertility, greenhouse gas production, and weathering. The soils SWIRL theme will provide bridges of interdisciplinarity and communication across the AGU membership to characterize and quantify soil processes from microbial to pedogenic scales.
AGU Biogeosciences Section Newsletter: Autumn 2013
This year our section will be making the first presentation of the Sulzman Award for Excellence in Education and Mentoring to Dr. Heidi Steltzer, Fort Lewis College, Durango, Colo., at the Biogeosciences Section Luncheon, held at the 2013 AGU Fall Meeting in San Francisco. Dr. Steltzer's outstanding creativity in teaching and her devotion to students are deserving of this honor. Read more.
AGU Chapman conference, Tucson, AZ, USA | 21-24 october 2013
The Technical committee on soil systems and critical zone processes will host a Chapman Conference on Soil-mediated Drivers of Coupled Biogeochemical and Hydrological Processes Across Scales. The conference will be held in Biosphere II, Tucson, AZ 21-24 October 2013: . This conference will facilitate an in-depth exchange of concepts and ideas on soil-mediated drivers of coupled hydrological and biogeochemical processes across spatial and temporal scales. Scientists from soil systems sciences, hydrology, and biogeochemistry will discuss these recent findings at the interface of soil, hydrology, and biogeochemistry. Four key fields of research will be addressed:
- coupled abiotic-biotic drivers of organic matter and nutrient transformations and transport across terrestrial-aquatic interfaces
- quantification and improved prediction of gas flux exchange in the soil-plant systems
- monitoring strategies of soil-mediated processes and drivers from local to catchment scales over time
- the soil resource as a primary driver of ecosystem services.
The conference is planned for four days and will consist of oral sessions, a poster session, four open workshop spaces, and a wrap-up session. The invited speakers, and volunteer speakers and contributors will be encouraged to publish their research in a conference proceedings or special issue/section of an international journal. The conference is open to all scientists interested in the proposed topics. We will pay specific attention to attracting early career scientists and Ph.D. students working on topics at the interfaces between the different disciplines, and specifically target underrepresented groups.
