Cosmogenic radionuclides
Sample preparation for 10Be, 26Al
The CRN-based geochemical technique allows us to quantify geomorphic process rates at the pedon, hillslope and catchment scale over time scales ranging from 103 to 105 years. This technique can be used to quantify long-term denudation rates, soil production and weathering rates, determine the rock exposure age, and to reconstruct the geomorphic history of soil and depositional landforms. In the geochemical laboratories at the Earth and Life Institute, we prepare soil, sediment and rock samples for in-situ 26Al and 10Be and meteoric 10Be analyses.
4D Earth surface monitoring using drones
Using RGB cameras mounted on customer-grade drones, we can monitor the earth surface at cm-resolution and precision. With Structure-from-Motion techniques, we can then produce digital models of the surface and ground topography, and vegetation structure. Repeated surveys with PPK (post-processing kinematic) GNSS supported drones provide us with accurate 4D reconstructions of geomorphic features (landslides, gullies, river banks) and vegetation structure.
