Deep Earth heat surprise
August 9, 2013
Researchers have for the first time, experimentally mimicked the pressure conditions of the Earths' deep mantle to measure thermal conductivity using a new measurement technique on the mantle material magnesium oxide. They found that heat transfer is lower than other predictions, with total heat flow across the Earth at about 10.4 terawatts, about 60 percent of the power used today by civilization.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2012, its budget was $7.0 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
