The Bay of Fundy (French: Baie de Fundy) is a bay located on the Atlantic coast of North America, on the northeast end of the Gulf of Maine between the Canadian provinces of New Brunswick and Nova Scotia, with a small portion touching the U.S. state of Maine. The Bay of Fundy is known for its high tidal range and the bay is contested as having the highest vertical tidal range in the world with Ungava Bay in northern Quebec. The name "Fundy" is thought to date back to the 16th century when the Portuguese referred to the bay as "Rio Fundo" or "deep river".[edit] Tidal electrical power generation
Several proposals to build tidal harnesses for electrical power generation have been put forward in recent decades. Such proposals have mainly involved building barrages which effectively dam off a smaller arm of the bay and extract power from water flowing through them.
One such facility, (the only one of its kind currently operating) the Annapolis Royal Generating Station consists of a dam and 18-MW power house on the Annapolis River at Annapolis Royal, Nova Scotia, but larger proposals have been held back by a number of factors, including environmental concerns. The Annapolis Royal Generating Station has been studied for its various effects, including an accelerated shoreline erosion problem on the historic waterfront of the town of Annapolis Royal, as well as increased siltation and heavy metal and pesticide contamination upstream due to lack of regular river/tidal flushing. There have also been instances where large marine mammals such as whales have become trapped in the head pond after transiting the sluice gates during slack tide.
Damming a large arm of the Bay of Fundy would have significant and not well-understood effects both within the dammed bay itself and in the surrounding regions. Intertidal habitats would be drastically affected and a facility would bring the bay closer to resonance, increasing tidal range over a very large area. One effect could be an increase in tidal range of 0.2 m (from approximately 1 m) for certain coastal sites in Maine, possibly leading to flooding.
There have been proposals in recent years for installing aquanators, the underwater equivalent to wind turbines, which would not require any damming or blockading of parts of the bay but would instead generate electricity solely by being placed in areas of high water flow, such as at choke points or merely along the floor of any part of the bay which sees significant water movement.
In order to claim this Earthcache please post 2 pictures of you and/or your GPS with the warf in the background. One at high tide and one at low tide. Please e-mail to me the approximate height of the tides.
