Streamlined subglacial bedforms across the deglaciated Northern Hemisphere ...
These data include shapefiles of streamlined subglacial bedforms, elongate bedforms created at the glacier-bed interface by erosional and depositional processes, characterized by polygons across nine deglaciated geographic locations in the Northern Hemisphere. Assessed deglaciated sites include the...
