p. 11. Watching the tidelocked

Abstract

The tide is the ocean’s response to the variation in gravitational pull of the Moon and the Sun over the surface of the Earth. ‘Watching the tide’ considers the importance of tides, from tide knowledge for safe navigation of ships in coastal waters to tides as a source of mechanical energy in the form of potential and kinetic energy. Tides also mix the sea, maintaining vertical circulation of the ocean and pumping heat from the tropics to the poles. Tidal rhythms (or harmonics), including diurnal and semi-diurnal tides, are discussed along with tidal range, neap tides, spring tides, and meteorological effects called surges, which can cause serious flooding.
