Katrina Lutz is a PhD Candidate in the Institute of Geography at the Friedrich-Alexander-University (FAU) in Erlangen, Germany under the supervision of Prof. Matthias Braun. Her research focuses on the remote sensing of supraglacial lakes in Northeast Greenland.

In this poster, we present four different methods for the remote estimation of supraglacial lake depth using Sentinel-2, ICESat-2, TanDEM-X, and sonar data. Furthermore, we assess the spatial and temporal variability of rapid lake drainages in Northeast Greenland. Our results outline the benefits and drawbacks of the different depth estimation techniques, especially in regard to large scale applicability and sensitivity of the methods to various environmental factors. Additionally, the complex nature of rapid drainages is highlighted through an analysis of several potential influencing factors.
