Physical Oceanographic Results of the "Calanus" Expeditions in Ungava Bay, Frobisher Bay, Cumberland Sound, Hudson Strait and Northern Hudson Bay, 1949–1955
Results of the physical oceanographic work of the "Calanus" expeditions of 1949–55 are presented in summary. Bathymetric maps are given for Ungava Bay, Frobisher Bay and northeast Hudson Bay. Temperature, salinity and density profiles are used to show the direction of flow of water, withou...
