Multibeam and marine sediment data were collected during three cruises with RV Sanna between 2018 and 2020 in Nuup Kangerlua fjords, Southwest Greenland. The goal of this project was to explore seafloor terrain and environment of the entire fjord system. Gridded multibeam data were analyzed for seafloor landforms using hillshade, slope, and profile analyses which are provided here as shapefiles. Landforms include glacial, fluvial, marine, and slope failure features.
