Dear Colleagues, I’d like to call your attention to and encourage abstract submissions to the following Ecohydrology session at the AGU Fall Meeting 2009. We look forward to seeing you in San Francisco. Apologies for cross-postings. H30: Tracers, Isotopes and Other Biogeochemical Techniques in Ecohydrology Description: Ecohydrology is at the forefront of addressing a number of outstanding challenges in earth surface processes, and is increasingly important in advancing our understanding in both hydrological and ecological sciences. While the use of tracers has been fundamental towards the advancement of hydrology, the interrelationships between ecology and hydrology suggests that tracers (e.g. Cl-, SF6, temperature, nutrients, DOC), isotopes (e.g. 15N, 13C, 18O), and other biogeochemical techniques (e.g., sap flux measurements in plants, soil chemistry, eddy covariance measurements of CO2 and H2O) may be equally appropriate to the field of ecohydrology. We invite contributions that highlight advancements or promising directions in the use of multiple approaches to address the co-organization of geochemical, hydrological and biological processes from hillslope to catchment scales. The session will include studies that integrate biogeochemical techniques with hydrologic and geotechnical approaches and/or ecosystem process modeling to enhance understanding of the spatial and temporal heterogeneity of catchment processes. Studies employing field based data collection and innovative methods of analysis and modeling are strongly encouraged, as well as numerical approaches towards resolving complex interactions involving biogeochemical techniques, tracers, and isotopes in ecohydrology across a range of spatial and temporal scales.
