The tides and tidal streams constitute one of the most important oceanographic features of the coastal waters of British Columbia. In addition to their clearly evident navigational significance, they strongly affect the distribution of salts, oxygen and temperature, and hence the character and distribution of marine life within the system.
Tides in these coastal waters are caused by the large scale tidal motions of the Pacific Ocean that are a response to the gravitational pulls of the moon and sun, and their changing character from day to day reflects the complex character of that response. Thus, as tidal crests and troughs move rapidly northward, past the open coasts, taking some 20 minutes to tra- verse the length of Vancouver Island, sympathetic os- cillations having the same periodic character propagate into the various coastal channels.
