  2. Tidal range - Wikipedia

    en.wikipedia.org/wiki/Tidal_range

    Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.

  3. Tide - Wikipedia

    en.wikipedia.org/wiki/Tide

    In Maine (U.S.), low tide occurs roughly at moonrise and high tide with a high Moon, corresponding to the simple gravity model of two tidal bulges; at most places however, the Moon and tides have a phase shift. Tide coming in, video stops about 1 + 1 ⁄ 2 hours before high tide Tide coming in

  4. Chart datum - Wikipedia

    en.wikipedia.org/wiki/Chart_datum

    Tide tables give the height of the tide above a chart datum making it feasible to calculate the depth of water at a given point and at a given time by adding the charted depth to the height of the tide. One may calculate whether an area that dries is under water by subtracting the drying height from the [given] height calculated from the tide ...

  5. Tide table - Wikipedia

    en.wikipedia.org/wiki/Tide_table

    Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...

    High tides occur 12 hours and 25 minutes apart. It takes 6 hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high,” according to the National Ocean Service ...

  8. Rule of twelfths - Wikipedia

    en.wikipedia.org/wiki/Rule_of_twelfths

    Officially produced tide tables should be used in preference whenever possible. The rule assumes that all tides behave in a regular manner, this is not true of some geographical locations, such as Poole Harbour [5] or the Solent [6] where there are "double" high waters or Weymouth Bay [5] where there is a double low water.

  9. Theory of tides - Wikipedia

    en.wikipedia.org/wiki/Theory_of_tides

    The Mediterranean Sea had two high tides and low tides, though Galileo argued that this was a product of secondary effects and that his theory would hold in the Atlantic. However, Galileo's contemporaries noted that the Atlantic also had two high tides and low tides per day, which led to Galileo omitting this claim from his 1632 Dialogue. [27]
