NOT A LOT OF PEOPLE KNOW THAT ………

• The biggest tides are in the Bay of Fundy (Nova Scotia) where a range of 57 ft (17.4m) is sometimes recorded.
• At Nokwakto Rapids (British Columbia) a tide speed of 16 knots has been observed.
• The tidal bulge, scraping along the bottom of ocean shallows, slows the earth's rotation by one second every 100,000 years.
• On the island of Euboea (Greece), the tidal current changes direction some 14 times a day, So far, nobody can explain why.
• The tidal cycle averages about 29.5 days and is reflected by the reproductive cycle of many plants and animals, including homo-sapiens.
• Even though New Moon and Full Moon exert the greatest gravitational pull on tides, there is such a huge mass of water to be shifted that the effects of these astronomical phenomena are not felt until about 36 hours after they occur.
• Spring and neap tides tend to occur at the same time of day at each cycle in every location, eg Dover HWS at 1200, LWN at 1230.
