GIS-based maps and area estimates of Northern Hemisphere permafrost extent during the Last Glacial Maximum
This study presents GIS-based estimates of permafrost extent in the northern circumpolar region during the Last Glacial Maximum (LGM), based on a review of previously published maps and compilations of field evidence in the form of ice-wedge pseudomorphs and relict sand wedges. We focus on field evi...
