GlaciDat – a GIS database of submarine glacial landforms and sediments in the Arctic
A digital database for submarine glacial landforms and sediments formed in the Arctic during and since the Last Glacial Maximum was created in order to facilitate and underpin new research on palaeo-ice sheets and tidewater glacier dynamics. The glacimarine database (GlaciDat) documents and standard...
