A Tidal Bore occurs when the leading edge of an incoming tide forms a wave of water that travels against the direction of the current. Tidal bores occur in relatively few locations worldwide, usually in areas with a large tidal range. Each day, this tidal phenomenon occurs in the Bay of Fundy.
The incoming Fundy tides are so powerful that they actually temporarily reverse the flow of several rivers that empty into the Minas Basin. The wave or crest of water that travels upriver as a result of this reversing flow is known as a tidal bore. The highest tides of the Bay of Fundy are due to the bay's unique shape and its ability to attract such a large amount of water. When this water enters the Bay of Fundy, it gradually narrows and becomes shallower. The tidal flow becomes constricted causing the water to rise.
The tides which have shaped the Bay of Fundy are responsible for providing nutrients that support the ecosystem, which in return supports the wildlife. The uniqueness of this body of water is heavily influenced by three distinct features; the gravitational pull of the moon, the unique shape of the bay and its substantial amount of water. Strong tidal currents of the Minas Basin are continuously eroding the red soils of the Fundy shoreline. The red soil becomes suspended in the water making it appear muddy.
Popular tidal bore viewing areas include the Salmon River in Truro, the Shubenacadie River in South Maitland as well as viewing areas on the Maccan River and the River Hebert. With some of the highest tides in the world, the Bay of Fundy is truly a natural wonder.
