BATHYMETRY OF THE BEAUFORT SEA
Oceanographic studies of the Beaufort Sea were made from ice-breakers during the summers of 1951, 1957, and 1958. Numerous echo-sounding lines were made across the shelf and slope, and into the deep Canada Basin. Between the Colville and Mackenzie River deltas, the shelf has a width of about forty n...
