Using UAVs to investigate effects of crevasses upon glacier surface melting, RiS-ID 11148

Tildelt: kr 77 999

The project involves the novel application of unmanned aerial vehicles (UAVs) to overcome the hazards associated with studying the effect of crevasses upon glacier surface melting. Firstly, we will derive a function with which a UAV can be used to estimate wind speed and direction. Secondly, we will deploy the drone over several Svalbard glaciers with different crevasse spacings in order to collect high-resolution aerial images of the surface and vertical profiles of wind. The wind profiles will then be used to calculate the aerodynamic roughness length which relate to turbulent surface heat fluxes. The images will be processed with a structure from motion (SFM) method to create a 3D digital elevation model (DEM) of the crevasse fields. The third and last part will be to produce empirical and physically-based models that describe the effect of crevasses on turbulent heat fluxes between the glacier surface and the atmosphere using experimental and numeric data.
