  • Essay / Tidal Power in the Bay of Fundy - 1579

    Environmental Report: Tidal Power in the Bay of FundyINTRODUCTIONThe Bay of Fundy, located off the coast of Nova Scotia, experiences the highest tides in the world. Extraordinary tides occur when the length of the tidal waves is two to four times the length of the bay. By virtue of blind luck or physics, the tide is amplified into a standing wave, like water sloshing in a bathtub. For a breaking wave to form, the rising tide must encounter an obstacle. When the ocean meets the river going in the opposite direction, the sea hesitates, piles up behind the front line and advances again in a tidal bore. Usually the ingredients occur during a new moon with 15 foot tides and the opposing force of the Shubenacadie River manifests. the true magnificence of the bay. This part of Saint John is divided into 3 main areas: the main harbour, Courtenay Bay and the outer harbour. These areas are influenced by the tides of the Bay of Fundy and the currents of the Saint John River which flow from the main harbor into the bay. This section also experiences two high tides and two low tides each day (semi-diurnal), with variable tidal range. 15 to 18 feet, depending on the type of tides. High water levels range from 22 to 28 feet and low water levels range from 0 to 7 feet above the map data. Because of these semi-diurnal tides and the action of the St. John River, slack water in the harbor occurs roughly at tides and not at high or low water as would be the case elsewhere. THE RHYTHMIC RISE AND DESCENT In the Bay of Fundy, the tides are spectacularly large. Although the rise and fall of sea level due to tides is the most apparent aspect, it is also tidal currents that direct the amplification of tides, and the rise or fall of sea level. sea ​​is due to the resulting convergences and divergences. These tides rise and fall over a range greater than 50 feet; such massive water movement, combined with the accumulation of sediment through erosion, has created a large salt marsh that provides a feeding station for migrating shorebirds. The low bottom also provides ground for marine life, including whales. A long time ago, about 15,000 to 10,000 years ago, the glacier retreated from...... middle of paper ......e so that when sufficient water level was reached between the land and sea sides of the dam. a mill could use tidal water to mix with fresh water to turn the water wheel which provided the power to grind the grain. The first mill on the island was built in 1607 by Samuel deChamplain on the Lequille River. In 1910, Turnbull and an American engineer designed a double basin project that would cross the international border between New Brunswick and Maine. CONCLUSION Given the serious environmental challenges such as global warning or environmental pollution that many types will face in the coming century and because the oceans play a very important role in governing the degree of global warming, the performance of fisheries and pollution levels along our beaches, studying tides through various means such as marine surveys and remote sensing will lead to a better understanding of how the oceans work. We hope to leave our children with a world that is both livable and pleasant in all its majesty. If we prevent oil spills into the ocean, the water and environment will be more beautiful and ecologically safer for all living things..
