Disentangling process from response in climate-tectonic interactions

Session ID#: 76315

Session Description:
Changes in climate and tectonic variables clearly influence the pace and pattern of erosion across Earth’s surface, but such changes do not occur in isolation. Interpreting the response of a landscape to externally driven perturbations is often complicated by the presence of multiple, sometimes opposing signals, as well autogenic feedbacks. In this complex web of interacting processes, how should we interpret a singular response?  We invite contributions from the surface processes and tectonics communities that use either field or model-based approaches to understand how topography and erosion reflect the balance between tectonic and climatic variables.  We will explore questions such as: 1) How do we distinguish changes in climatic variables from tectonic variables in topographic analysis? 2) What are the best approaches for measuring degrees of landscape disequilibrium? 3) What is the appropriate timescale over which to interpret landscape equilibrium? 4) Are changes to topography necessarily continuous or episodic?
