Earth’s magnetic fields could track ocean heat, NASA study finds
13 December 2016
As Earth warms, much of the extra heat is stored in the planet's ocean – but monitoring the magnitude of that heat content is a difficult task.
A surprising feature of the tides could help, however. Scientists at NASA's Goddard Space Flight Center in Greenbelt, Maryland, are developing a new way to use satellite observations of magnetic fields to measure heat stored in the ocean.
