  2. Ocean current - Wikipedia

    en.wikipedia.org/wiki/Ocean_current

    Knowledge of surface ocean currents is essential in reducing costs of shipping, since traveling with them reduces fuel costs. In the wind powered sailing-ship era, knowledge of wind patterns and ocean currents was even more essential. Using ocean currents to help their ships into harbor and using currents such as the gulf stream to get back ...

  3. Deep sea mining - Wikipedia

    en.wikipedia.org/wiki/Deep_sea_mining

    According to the International Union for Conservation of Nature: "Not only is deep-sea mining an energy-intensive industry with high greenhouse gas emissions, but disruption of the ocean floor, which is by far the largest carbon storage reservoir on Earth, can lead to reduced carbon sequestration as well as the release of large amounts of the ...

  4. 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 ...

  5. Marine energy - Wikipedia

    en.wikipedia.org/wiki/Marine_energy

    Ocean currents are instrumental in determining the climate in many regions around the world. While little is known about the effects of removing ocean current energy, the impacts of removing current energy on the farfield environment may be a significant environmental concern. The typical turbine issues with blade strike, entanglement of marine ...

  6. Seabed mining - Wikipedia

    en.wikipedia.org/wiki/Seabed_mining

    Model of seabed mining technology. Seabed mining, also known as Seafloor mining [1] is the recovery of minerals from the seabed by techniques of underwater mining. The concept includes mining at shallow depths on the continental shelf and deep-sea mining at greater depths associated with tectonic activity, hydrothermal vents and the abyssal plains.

  7. Antarctic Circumpolar Current - Wikipedia

    Surveys of the SW Indian Ocean have shown phytoplankton group variation based on their location relative to the Polar Front, with diatoms dominating South of the front, and dinoflagellates and flagellates in higher populations North of the front. [16] Some research has been conducted on Antarctic phytoplankton as a carbon sink. Areas of open ...

    The sheets were revealed by sonar, officials say. Divers investigating mysterious sheets of steel on the seafloor off Guam have discovered what amounts to a sunken trail in the Pacific Ocean.

  9. Oceanography - Wikipedia

    en.wikipedia.org/wiki/Oceanography

    It is an Earth science, which covers a wide range of topics, including ocean currents, waves, and geophysical fluid dynamics; fluxes of various chemical substances and physical properties within the ocean and across its boundaries; ecosystem dynamics; and plate tectonics and seabed geology.
