Abstract


Techniques are now available to prepare bathymetric maps of the sea floor with detail similar to that of topographic maps on land. Gridded data sets can be displayed as shadowgrams to enhance particular morphologic features. Glacial geomorphological features on the continental shelf off eastern Canada can be interpreted in a manner analogous to glacial features on land. The last major dataset acquired by the CSS BAFFIN from the eastern Scotian Shelf shows a complex topography interpreted as a series of glacial tunnel valleys, which indicate several episodes of sub-glacial meltwater flow and erosion.
