| Abstract | (Summary)
A new glacial geomorphology map covers 415 000 km2 in a core region of the Laurentide Ice Sheet in Nunavut. The compilation builds on recent and legacy maps and is supplemented by
visual digitization of glacigenic features using high-resolution digital elevation (ArcticDEM) and Landsat 8 images. From this unprecedented, detailed inventory of >152 000 features and >14 000 field observations, various glacial land systems were
identified, many of which are entirely new and others that are significantly modified or updated. |
