A new gravity map of Earth

Gravity differs from place to place around Earth because of the uneven distribution of mass across and within the planet. Scientists can study the variation in gravitational pull by measuring the gravity field at different places on the surface of the planet. In a new study published in Scientific Reports, gravity field data collected over the entire planet between 2009 and 2013 by the European Space Agency’s Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite has been mapped, revealing many of Earth’s internal features, such as magmatic plumes welling up toward the surface.
