Queen Charlotte Sound
Together with the complex ocean floor, the high tides in the Sound create a rugged shoreline
The continental shelf of Queen Charlotte Sound has an average depth, so the tidal amplitude is close to the usual value of 2.5 metres. However, the ocean floor in this region is complex, with deep basins, shallow banks and channels. This complexity causes turbulent waters and whirlpools to appear with each incoming tide. These rough waters batter the coasts of the Queen Charlotte Islands, giving them their characteristic rugged appearance.
