Development of a pan-Arctic drained lake basin product

Local and regional assessments indicate that drained lake basins (DLBs) are a prominent landscape feature in lowland permafrost regions around the pan-Arctic. Despite this recognition, a pan-Arctic assessment of DLB distribution and their carbon stores has never been attempted. A coordinated pan-Arctic scale effort is needed to better understand the importance of DLBs in permafrost-regions across the pan-Arctic.
Our Action Group will focus on the development of a pan-Arctic DLB product that will fill a fundamental knowledge gap in permafrost-region landscapes with implications for global-scale climate feedbacks. A comprehensive pan-Arctic DLB dataset will be of great interest to
the scientific community and will benefit researchers working on projects from many different disciplines (e.g., hydrological modelling, engineering, and carbon cycling).
