“How tectonic and surface processes interact to shape the landscape”
The landscape serves as a link between the solid Earth and the atmosphere. At many spatial and temporal scales, landscape morphology and topography provide a constraint on the tectonics of the Earth and processes active within it. To unravel these, we need to understand the complex relationships between surface processes, their drivers and the rocks upon which they act. I will explore recent developments in modelling tectonics and surface processes within a single deformational framework. I will focus on collisional settings such as New Zealand’s Southern Alps, SE Alaska and the Himalaya where rapid uplift combines with vigorous climate regimes to create dynamic landscapes.
Bio: Phaedra Upton is the Geodynamics Team Leader at GNS Science, where she has worked for the last 11 years. She has widely published on oblique collisional plate boundaries including the Southern Alps. More recently, tectonic geomorphology has become her main focus. As a modeller, Phaedra tries to bring practical and sensible numerical modelling approaches to a wide range of Earth Science topics, from large scale processes in the deep crust through to surface processes of active erosion and sedimentation. She is adept at using these models in collaboration with geologists from a range of subdisciplines to produce insights into the various processes and time scales involved.
