Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Four stages in the tidal cycle are low, high, flood (sea level rising) and ebb (sea level falling). Oscillating currents produced are known as tidal streams or currents. The moment that the current ceases is called slack water or slack tide, which then reverses direction and is said to be turning. Tides are commonly semi-diurnal (two high waters and two low waters each day), or diurnal (one cycle per day). While tides are usually the largest source of short-term sea-level fluctuations, sea levels are also affected by thermal expansion, wind, barometric pressure changes, and storm surges.

A video I shot of Mitchell Bay, Alaska dumping water out on ebb. Similar to the Saltstraumen in Norway, that current rips!
