  2. 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 ...

  3. Tide clock - Wikipedia

    en.wikipedia.org/wiki/Tide_clock

    The 16th-century church clock at Arnemuiden indicates the time of local high tide as a pointer on a 12-hour clockface. Maassluis. Jacob Venker's tide clock on the exterior of the Nationaal Sleepvaart Museum was installed in 1996. Despite the clock's traditional dial, it is computer-controlled, and accounts for 94 waves in its tidal timekeeping.

  4. Tide table - Wikipedia

    Tidal Word Wave artwork by Adrian Riley and Rachel Welford Time and Tide Bell is an art project made up of bells, designed by sculptor Marcus Vergette , installed at coastal locations in the UK. Each bell rings at high tide, and rising sea levels caused by global warming will change the sounds made by the bells.

  5. Nautical time - Wikipedia

    en.wikipedia.org/wiki/Nautical_time

    Time on a ship's clocks and in a ship's log had to be stated along with a "zone description", which was the number of hours to be added to zone time to obtain GMT, hence zero in the Greenwich time zone, with negative numbers from −1 to −12 for time zones to the east and positive numbers from +1 to +12 to the west (hours, minutes, and ...

  6. Tide - Wikipedia

    en.wikipedia.org/wiki/Tide

    The time when the crest of the wave reaches a port then gives the time of high water at the port. The time taken for the wave to travel around the ocean also means that there is a delay between the phases of the Moon and their effect on the tide.

  7. Theory of tides - Wikipedia

    en.wikipedia.org/wiki/Theory_of_tides

    The second strongest tidal constituent "S 2" is influenced by the sun, and its Doodson numbers are 273.555, meaning that its frequency is composed of twice the first Doodson argument, +2 times the second, -2 times the third, and zero times each of the other three. [50] This aggregates to the angular equivalent of mean solar time +12 hours.

  9. Atmospheric tide - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_tide

    Tidal waves can be either internal (travelling waves) with positive eigenvalues (or equivalent depth) which have finite vertical wavelengths and can transport wave energy upward, or external (evanescent waves) with negative eigenvalues and infinitely large vertical wavelengths meaning that their phases remain constant with altitude.
