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.
Computer models of ocean circulation increasingly place most of the deep upwelling in the Southern Ocean, associated with the strong winds in the open latitudes between South America and Antarctica. [28] Direct estimates of the strength of the thermohaline circulation have also been made at 26.5°N in the North Atlantic, by the UK-US RAPID ...
The road begins at the end of the Dempster Highway in Inuvik, Northwest Territories and continues for 138 km (86 mi) north towards Tuktoyaktuk, a coastal community on the Arctic Ocean. The ITH includes eight bridges, and is a two-lane gravel road for its entirety. [ 16 ]
The Ocean Thermal Energy Conversion Act of 1980 (OTECA) is an act authorized by Congress to address ocean thermal conversion. It is one of six acts enacted by the Energy Security Act of 1980. [ 1 ] Ocean thermal energy conversion is the extraction of energy from the thermal differentials of subsea and surface water in regions with tropical oceans.
A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with depth.
Open ocean convection is a process in which the mesoscale ocean circulation and large, strong winds mix layers of water at different depths. Fresher water lying over the saltier or warmer over the colder leads to the stratification of water, or its separation into layers. Strong winds cause evaporation, so the ocean surface cools, weakening the ...
The chemical and thermal dynamics in hydrothermal vents makes such environments highly suitable thermodynamically for chemical evolution processes to take place. Therefore, thermal energy flux is a permanent agent and is hypothesized to have contributed to the evolution of the planet, including prebiotic chemistry.
The Costa Rica dome is a biodiversity hotspot for marine life. [1] The presence of a seasonally predictable strong and shallow thermocline associated with cyclonic circulation and upwelling make the Costa Rica Dome a distinct biological habitat, with zoo-plankton and phytoplankton biomass significantly higher than in the tropical waters surrounding it.
