Gravity variations much bigger than previously thought

A joint Australian-German research team led by Curtin University's Dr Christian Hirt has created the highest-resolution maps of Earth's gravity field to date - showing gravitational variations up to 40 per cent larger than previously assumed.
Using detailed topographic information obtained from the US Space Shuttle, a specialist team including Associate Professor Michael Kuhn, Dr Sten Claessens and Moritz Rexer from Curtin's Western Australian Centre for Geodesy and Professor Roland Pail and Thomas Fecher from Technical University Munich improved the resolution of previous global gravity field maps by a factor of 40.
