  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]

  3. Beaufort Gyre - Wikipedia

    en.wikipedia.org/wiki/Beaufort_Gyre

    In a clockwise-rotating gyre in the Northern Hemisphere, the Coriolis force causes the ocean water to flow inward toward the gyre's center where it accumulates, effectively forming a dome of water. If the wind patterns shift into a cyclonic circulation due to the residence of a low pressure system (rising air induced by warmer ocean ...

  4. South Pacific Gyre - Wikipedia

    en.wikipedia.org/wiki/South_Pacific_Gyre

    Earth's trade winds and Coriolis force cause the ocean currents in South Pacific Ocean to circulate counterclockwise. The currents act to isolate the center of the gyre from nutrient upwelling, and few nutrients are transported there by the wind (eolian processes) because there is relatively little land in the Southern Hemisphere to supply dust to the prevailing winds.

  5. Ocean gyre - Wikipedia

    en.wikipedia.org/wiki/Ocean_gyre

    In oceanography, a gyre (/ ˈ dʒ aɪ ər /) is any large system of ocean surface currents moving in a circular fashion driven by wind movements. Gyres are caused by the Coriolis effect; planetary vorticity, horizontal friction and vertical friction determine the circulatory patterns from the wind stress curl ().

  6. 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 ...

    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. A system of ocean currents that transports heat northward across the North Atlantic could collapse by mid-century, according to a new study, and scientists have said before that such a collapse ...
