  2. Ocean current - Wikipedia

    en.wikipedia.org/wiki/Ocean_current

    Ocean currents are important in the study of marine debris. [15] [16] Plankton are dispersed by ocean currents. Upwellings and cold ocean water currents flowing from polar and sub-polar regions bring in nutrients that support plankton growth, which are crucial prey items for several key species in marine ecosystems. [17]

    Further is the fluid density, is the cross product operator, = ^ where = ⁡ is the Coriolis parameter (with the Earth's rotation angular speed and ⁡ the sine of the latitude) and ^ is the unit vector in the vertical upward direction (opposing the Earth's gravity).

  4. Geostrophic current - Wikipedia

    en.wikipedia.org/wiki/Geostrophic_current

    A geostrophic current may also be thought of as a rotating shallow water wave with a frequency of zero. The principle of geostrophy or geostrophic balance is useful to oceanographers because it allows them to infer ocean currents from measurements of the sea surface height (by combined satellite altimetry and gravimetry ) or from vertical ...

  5. Atlantic meridional overturning circulation - Wikipedia

    A summary of the path of the thermohaline circulation. Blue paths represent deep-water currents, while red paths represent surface currents. The NADW is not the deepest water layer in the Atlantic Ocean; the Antarctic bottom water (AABW) is always the densest, deepest ocean layer in any basin deeper than 4,000 metres (2.5 mi). [27]

  6. Ekman spiral - Wikipedia

    en.wikipedia.org/wiki/Ekman_spiral

    The Ekman spiral is an arrangement of ocean currents: the directions of horizontal current appear to twist as the depth changes. [1] The oceanic wind driven Ekman spiral is the result of a force balance created by a shear stress force, Coriolis force and the water drag. This force balance gives a resulting current of the water different from ...

    A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster ...

  9. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Winds drive ocean currents in the upper 100 meters of the ocean's surface. However, ocean currents also flow thousands of meters below the surface. These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation.
