The pan-Arctic catchment database (ARCADE)

[摘要] The Arctic is rapidly changing. Outside the Arctic, large-sample catchmentdatabases have transformed catchment science from focusing on local casestudies to more systematic studies of watershed functioning. Here we presentan integrated pan-ARctic CAtchments summary DatabasE (ARCADE) of >  40 000 catchments that drain into the Arctic Ocean and range insize from 1 to 3.1  ×  10 6  km 2 .These watersheds, delineated at a 90 m resolution, are provided with 103geospatial, environmental, climatic, and physiographic catchment properties.ARCADE is the first aggregated database of pan-Arctic river catchments thatalso includes numerous small watersheds at a high resolution. These smallcatchments are experiencing the greatest climatic warming while also storinglarge quantities of soil carbon in landscapes that are especially prone todegradation of permafrost (i.e., ice wedge polygon terrain) and associatedhydrological regime shifts. ARCADE is a key step toward monitoring thepan-Arctic across scales and is publicly available: https://doi.org/10.34894/U9HSPV (Speetjens et al., 2022).
