| contents | DARTS: Multi-year database of AI-detected retrogressive thaw slumps in the circum-arctic permafrost region. Nitze, Ingmar Heidler, Konrad Nesterova, Nina Küpper, Jonas Schütt, Emma Hölzer, Tobias Barth, Sophia Lara, Mark J Liljedahl, Anna K Grosse, Guido Retrogressive Thaw Slumps (RTS) are widespread mass-wasting hillslope failures triggered by thawing permafrost. While regional studies have provided insights into the spatial distribution and dynamics of RTS, a consistent and unbiased quantification and monitoring remains unsolved at pan-arctic scales. We present the Database of AI-detected Arctic RTS footprints (DARTS), comprising ~43,000 individual footprints of active RTS or active areas within larger RTS landforms. DARTS spans ~1.6 million km from 2018-2023, with at least annual coverage from 2021-2023 across a ~900,000 km region. The database is freely available in two processing levels: sub-annual and annually aggregated polygon footprints including spatial and tabular metadata. DARTS uses a highly automated workflow based on deep learning segmentation of PlanetScope multi-spectral satellite imagery (3-5 m resolution) and elevation data. Validation against different regional RTS datasets yielded F1 scores ranging from 0.263 to 0.700, with higher accuracy in areas of intense RTS activity. DARTS provides a valuable resource for systematically mapping, quantifying, and analyzing active hillslope thermokarst distribution and changes over time across the circum-arctic permafrost region. |
