Theme 1: Measuring the Critical Zone
Chairman: Lin Ma
In this session, we encourage submissions on measurement and long term monitoring of the critical zone. This may include instrumental observations (in particular, high frequency measurements), subsurface imaging, concentration-discharge relationships, mass budgets of matter and energy, and metrics of rates and residence times, as well as proposals for a metrics of the Critical Zone. This session is open to submissions from individual sites or from networks of sites.

Theme 5: Isotopes in the Critical Zone
Chairman: Julien Bouchez
This session will explore the use of isotopes to probe critical zone processes. In particular, recent technical advances have made possible the measurement of previously difficult isotopes. These “non traditional” isotopes provide a new window on processes in the Critical Zone. Studies based on experiment and ab initio calculations are expected in this session together with field-based approaches.

Theme 6: Characteristic timescales of the Critical Zone
Chairman: Francois Chabaux
This session aims at synthetizing studies related to rate of formation/destruction and characteristic timescale of the critical zone. This includes the use of cosmogenic isotopes, short-period radionuclides and other techniques such as OSL and thermochronology to infer about residence time of material in mobile layers, residence time in the CZ, rates of weathering, denudation, water residence times, time to respond to climate perturbations (in ecosystem structure, solute/sediment flux, in topography or soil thickness).

08:25 - 10:30 : Theme 7: The Critical Zone and the geological evolution of the biogeochemical cycles
Theme 7: The Critical Zone and the geological evolution of the biogeochemical cycles
Chairman: Karl Steefel
In this session, we wish to explore the couplings between Critical Zone functioning and the evolution of global biogeochemical cycles through geological time. The role of weathering in the Earth‘s climatic evolution is related to tectonics, physical erosion, relief and the evolution of life. We encourage submissions on those couplings and on the evolution of atmospheric CO2, based on experimental, field or modeling approaches.

Chairman: Jens Hartmann
The idea of the session is to explore the links between the Critical Zone concept and Global Changes. Terrestrial surfaces play a major role in the evolution of not only climate but also on the sustainability of water and the soil resource. We encourage submissions in this session on the importance of understanding the critical zone of the Earth in climate models, agricultural studies, fate and behavior of contaminants and environmental geochemistry. The session also aims at exploring the geo-engineering of the Critical zone.
