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.
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.
The ocean heat content (OHC) has been increasing for decades as the ocean has been absorbing most of the excess heat resulting from greenhouse gas emissions from human activities. [1] The graph shows OHC calculated to a water depth of 700 and to 2000 meters. Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored ...
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.
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 ...
NOAA NODC WOA05 is the World Ocean Atlas 2005, an atlas of objectively analyzed fields of major ocean parameters at monthly, seasonal, and annual time scales. In situ observations spanning from the early 1700s to present are available from the International Comprehensive Ocean Atmosphere Data Set (ICOADS).
Surface temperatures in the western North Atlantic: Most of the North American landmass is black and dark blue (cold), while the Gulf Stream is red (warm). Source: NASA The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude ...
William Hinckley Avery (July 25, 1912 – June 26, 2004) was an influential aeronautical engineer.He designed the propulsion mechanism known as the ramjet, and was known for heading the Ocean Thermal Energy Conversion program which generates electricity from the temperature differential between shallow and deep ocean water.
