Quantifying rates of erosion and weathering is key in understanding and modelling the evolution of the Earth’s surface and to constrain the control of these processes on the major bio-geochemical cycles. The aim of this session is to bring together researchers from different scientific communities working on different aspects of the determination of erosion and weathering rates, across a range of temporal and spatial scales. We seek investigators using the full range of experimental and modelling approaches to investigate geomorphologic, geochemical and biological parameters and their coupling in weathering and erosion processes, in natural as well as experimental environments. We especially encourage contributions focusing (1) on the development of new geochemical and/or geomorphologic tools for determining the rates of weathering and erosion processes, (2) on how the coupling between soil production and sediment transport are influenced by climate variability, tectonic activity and human disturbance, and (3) on how palaeo-records can help to recover variations of these parameters over geologic time. This session is therefore open to the study of weathering/erosion systems from the past to the present day.
