There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Using Environmental Tracers to Unravel Hydrological and Geochemical Controls from the Water-Mineral Interface to Large River Basins
Water-rock interactions serve a fundamental role in terrestrial water and biogeochemical cycles. Solute generation and mobilization arising from fluid contact with subsurface minerals constituents creates the quality of our surface and groundwaters, sustains ecosystems, shapes the evolution of landscapes, and regulates atmospheric CO2.
Application of environmental tracers such as radiogenic and stable isotopes as well as trace elements offers a promising approach in characterizing these interactions and associated geochemical and hydrological processes giving rise to observed solute dynamics.
In this talk, I build upon our current knowledge of stable isotope and trace element fractionation during water-rock interactions and how they manifest from the laboratory to catchment scale. I will also present some future directions in the application of radiogenic groundwater age tracers to infer storage, flow, and solute transport behavior at the regional scale
