p. 585. Dynamic oceanlocked

  • Dorrik Stow


‘Dynamic ocean’ explains the movement of water and energy in the oceans. Almost all surface waves are generated by wind stress with the three stages in wave development known as sea, swell, and surf. Tides are created by the gravitational pull of the Moon and the Sun and by a centrifugal force due to the rotation of the Earth. The pattern of circulation results from a more complex interaction of wind drag, pressure gradients, and Coriolis deflection resulting in gyres, loops, and eddies. Slow-moving currents in the deep ocean basins transfer energy, nutrients, and sediments around the world. These currents are driven by density differences linked to water temperature and salinity and are part of the global thermohaline circulation system.
