Dear colleagues,

Please consider submitting an abstract to our Goldschmidt session SESSION # 11J: CRITICAL ZONE (CZ) EXPORT TO STREAMS AND GROUND WATER AS INDICATOR FOR CZ FUNCTIONS IN THE ANTHROPOCENE: CHALLENGES AND OPPORTUNITIES. Submission deadline is April 1st. Jérôme Gaillardet will give the keynote. Hope to see you in Paris!!

Here is the session description: Pollution, droughts, floods, recharge processes and water provenance, ground-surface water connection, weathering and erosion rate are deeply connected to critical zone (CZ) structure and function. To trace important processes such as ground water recharge, geochemical reactions e.g. along flow paths as well as water provenance and transit times, several geochemical tools (i.e. major, trace elements, isotopes) are used. However, how much can we learn about CZ processes from probing stream and ground water and what are the limitations? How can we integrate temporal (inter-annual, seasonal, diel) variations, the balance between event and base flow dynamics to trace the variety of (bio)geochemical processes shaping the CZ? We invite contributions that link field observations and /or models to biogeochemical, hydrological, ecological, biological and pedological processes in traditional and novel ways to relate water dynamics back to CZ function in a time of accelerated global change.
