  2. Mars ocean theory - Wikipedia

    en.wikipedia.org/wiki/Mars_ocean_theory

    Because centrifugal force causes spinning objects and large rotating objects to bulge at their equator (equatorial bulge), the polar wander could have caused the shoreline elevation to shift in a similar way as observed. [13] [19] [20] Their model does not attempt to explain what caused Mars's rotation axis to move relative to the crust.

  3. Ocean current - Wikipedia

    Ocean surface currents Distinctive white lines trace the flow of surface currents around the world. Visualization showing global ocean currents from January 1, 2010, to December 31, 2012, at sea level, then at 2,000 m (6,600 ft) below sea level Animation of circulation around ice shelves of Antarctica

  4. Tide - Wikipedia

    en.wikipedia.org/wiki/Tide

    The theoretical amplitude of oceanic tides caused by the Moon is about 54 centimetres (21 in) at the highest point, which corresponds to the amplitude that would be reached if the ocean possessed a uniform depth, there were no landmasses, and the Earth were rotating in step with the Moon's orbit. The Sun similarly causes tides, of which the ...

    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 ...

  6. Marine current power - Wikipedia

    en.wikipedia.org/wiki/Marine_current_power

    Marine currents can carry large amounts of water, largely driven by the tides, which are a consequence of the gravitational effects of the planetary motion of the Earth, the Moon and the Sun. Augmented flow velocities can be found where the underwater topography in straits between islands and the mainland or in shallows around headlands plays a major role in enhancing the flow velocities ...

    Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests. The findings released Monday are based on ...

  8. 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 crucial system of ocean currents may already be on course to collapse, ... The AMOC’s collapse could also cause sea levels to surge by around 1 meter (3.3 feet), van Westen said.
