  2. 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 ...

  3. 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 ...

  4. Effects of climate change on oceans - Wikipedia

    en.wikipedia.org/wiki/Effects_of_climate_change...

    Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored by oceans. To calculate the ocean heat content, it is necessary to measure ocean temperature at many different locations and depths. Integrating the areal density of a change in enthalpic energy over an ocean basin or entire ocean gives the total ocean heat ...

  5. 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 ...

  6. 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 ...

  7. Baroclinic instabilities in the ocean - Wikipedia

    en.wikipedia.org/wiki/Baroclinic_instabilities...

    A baroclinic instability is a fluid dynamical instability of fundamental importance in the atmosphere and ocean. It can lead to the formation of transient mesoscale eddies, with a horizontal scale of 10-100 km. [1] [2] In contrast, flows on the largest scale in the ocean are described as ocean currents, the largest scale eddies are mostly created by shearing of two ocean currents and static ...

  8. Ocean thermal energy conversion - Wikipedia

    en.wikipedia.org/wiki/Ocean_thermal_energy...

    An ocean thermal energy conversion power plant built by Makai Ocean Engineering went operational in Hawaii in August 2015. The governor of Hawaii, David Ige, "flipped the switch" to activate the plant. This is the first true closed-cycle ocean Thermal Energy Conversion (OTEC) plant to be connected to a U.S. electrical grid.

  9. Direct deep-sea carbon dioxide injection - Wikipedia

    en.wikipedia.org/wiki/Direct_deep-sea_carbon...

    Convective motion over the surface of the lake due to ocean bottom storms or normal sea currents will increase dissolution. Without any bulk flow over the lake, the storage timeline of the carbon dioxide is 10,000 years for a 50 m deep lake. This number is decreased by more than 25 times with currents from ocean bottom storms. [2]
