"The Royal Society next sent Sabine on a pendulum expedition in 1821-1822 around the Atlantic to determine the true figure of the earth, a project that brought him the Copley Medal. A pattern was developing in his work, clearly of a Humboldtian nature - the gathering and analysis of geophysical data on a large, ever global, scale. While the range of Sabine’s interests was wide, terrestrial magnetism attracted most of his attention."(DSB). - Sabin, 74699.
