AbstractIn areas where bedrock outcrops are situated between converging glaciers, longitudinal debris accumulations mark the boundary between adjacent ice-flow units. These medial moraines often give the glacier surface a striped appearance. The seafloor offshore from Scott Inlet, Arctic Canada, exhibits well-preserved medial moraines and other elongate features. These elongate submarine landforms allow the reconstruction of the flow direction of the Laurentide Ice Sheet during the Late Glacial Maximum c. 24-23 14C ka BP (Dyke et al. 2002).
Summary(Plain Language Summary, not published)
Longitudinal debris accumulations or medial moraines on glacier surfaces often give the ice a striped appearance. In areas where bedrock outcrops are situated between converging glaciers, medial moraines mark the boundary between adjacent flow units. The seafloor offshore from Scott Inlet, Arctic Canada, exhibits well-preserved medial moraines and other elongate features which allow the reconstruction of the direction of ice flow of the Laurentide Ice Sheet during the Late Glacial Maximum about 24,2314C ka BP.
