A digital database for glacial landforms and sediments formed in the Arctic during and since the Last Glacial Maximum (LGM) was created in order to facilitate and underpin new research on palaeo-ice sheets and tidewater glacier dynamics. The database is in geographic information system (GIS) format and is available for web download. It documents evidence of previous glacial activity as visible on the contemporary seafloor of fjords and continental shelves around all of Svalbard, Greenland, Alaska, and northern Russia, as well as north of 66°30' N in Canada and Norway. Extensive literature research was conducted to create the database, compiling a total of nearly 60,000 individual submarine landforms, more than 1,000 sediment cores, and around 230 radiocarbon dates. Glacial landforms included in the database are cross-shelf troughs, trough-mouth fans, grounding-zone wedges, overridden moraines, (mega-scale) glacial lineations, drumlins, crag-and-tails, medial moraines, terminal moraines, debris-flow lobes ...
