It is here that the greatest tides on Earth occur to prove that the Atlantic Ocean is in a constant state of movement. 115 billion tons of water move in and out of the Bay twice a day. The tide here is five times higher than the Atlantic Coast average with tides ranging from a low of 3.5 metres (11ft) to an incredible 16 metres (53ft) at its zenith.
The reason for the high tides can be tied down to a quirk of nature. Put simply it is called tidal resonance. This has to do with the speed at which a wave moves, and it is waves which signal the rise and fall of tides, which are affected by the pull of gravity by the moon. So, the time it takes a large wave to go from the mouth of the bay to the inner shore and back is practically the same as the time from one high tide to the next, hence there is always a large volume of water on the move, which creates the higher tides.
Water is abrasive, so the great flow has eaten into the bay’s rocks over a great period of time, creating an abundance of cliffs with overhanging caves. Therefore, the scenery around the bay can be quite spectacular. The erosion has also revealed thousands of fossils that were buried within the rocks, o that the world’s largest collection of 300 million year-old fossils are now on display at the Joggins Fossil Centre.
With such a huge abundance of nutrient-rich water it means that the waters around the bay are teeming with marine life, and whale watching tours are popular. A great many varieties of whales can be seen, including the Fin Whale, which is the world’s second largest whale after the Blue Whale.
For those who love adventure, you can go Tidal Bore Rafting in the Bay of Fundy. Perched aboard a Zodiac, adventurers enjoy the thrill of surfing a genuine tidal bore. This is one way to truly appreciate just how swift and amazing the tides are as the waters can rise about ten metres during the few hours for which the tour lasts.
There is plenty of accommodation and other sightseeing around the bay, but the main event is definitely the tide which can amaze sightseers with the speed at which it appears, drowns everthing, then disappears again.
