Description	This ice-marginal lake dataset is a series of annual inventories, mapping the extent and presence of lakes across Greenland that share a margin with the Greenland Ice Sheet and/or the surrounding ice caps and periphery glaciers. The annual inventories provide a comprehensive record of all identified ice marginal lakes, which have been detected using remote sensing techniques. The inventory series was created to better understand the impact of ice-marginal lake change on the future sea level budget and the terrestrial and marine landscapes of Greenland, such as its ecosystems and human activities. The dataset is a complete inventory series of Greenland, with no absent data. Terms of use If the data are presented or used to support results of any kind, please include an acknowledgement and references to the applicable publications: How, P. et al.

Rep. 11, 4481. https://doi.org/10.1038/s41598-021-83509-1 Detailed description The detected lakes are presented as polygon vector features in GeoPackage format (.gpkg), with coordinates provided in the WGS NSIDC Sea Ice Polar Stereographic North (EPSG:3413) projected coordinate system. All data were compiled and filtered in a semi-automated approach, using Klimatdatastyrelsen Åbent Land Grønland dataset (https://dataforsyningen.dk/data/4771) to clip the dataset to within 1 km of the ice margin. Each detected lake was then verified manually. The methodology is open-source and provided at https://github.com/GEUS-Glaciology-and-Climate/GrIML for full reproducibility. Please consult the readme provided here for further information on the dataset metadata. Methodologies and production are described in the associated data description publication. Acknowledgements The inventory series of ice-marginal lakes in Greenland has been produced as part of the European Space Agency (ESA) Living Planet Fellowship project "Examining GReenland’s Ice Marginal Lakes under a changing climate (GrIML)", which is a follow-on effort to the 2017 inventory of ice-marginal lakes created under the European Space Agency (ESA) Climate Change Initiative (CCI) in Option 6 of the Glaciers_cci project (4000109873/14/I-NB). Upkeep and continuation of the inventory series is supported by PROMICE, funded by the Geological Survey of Denmark and Greenland (GEUS) and the Danish Ministry of Climate, Energy and Utilities, conducted in collaboration with DTU Space (Technical University of Denmark) and Asiaq Greenland Survey.
