About the project
This project will examine how wind-blown avalanches are imprinted on aeolian dune stratigraphy on Earth and Mars. It involves laboratory experiments, field work and planetary remote sensing. Ultimately the research outcomes will provide unique, cutting-edge insight into the influence of avalanche dynamics on aeolian dune migration, both modern and ancient.
Avalanching is responsible for wind-blown dune migration on Earth and Mars and because avalanches are preserved in dune stratigraphy, they are the most direct way that we can interpret past wind-climate conditions.
Recent evidence suggested avalanche magnitude is driven by grainfall dynamics which link to wind speed and observations of avalanches have been made on a Martian.
However, without a better grasp of the process-form feedbacks between dune size and avalanche drivers, it is impossible to interpret the ancient wind climates that formed dune environments now preserved in the rock record both on Earth and Mars.
This PhD will use the latest technology to measure avalanches remotely and supplement field experiments with laboratory replicates within the School of Geography and Environmental Sciences aeolian avalanche slope facility.
