This visualization of a gravity model was created with data from NASA's Gravity Recovery and Climate Experiment (GRACE) and shows …These anomalies are caused by variations in the gravitational pull of the Earth due to differences in the density of the materials that make up the Earth’s crust. When there is a gravitational anomaly, there is a region where the gravitational pull is stronger or weaker than in the surrounding areas, which can cause a gravity hole to form. Gravity is measurable as a force, which means it can be described in Newtons (N). A Newton is the international standard unit of force. Force is different on other planets, stars, or the moon, but on Earth’s surface, 0.98N is equal to the d...1.11.4.1 Gravity Anomalies.

Similarly, the traditional isostatic gravity anomaly and disturbance have the same topographic and compensation effects (see Eqs.Dec 11, 2012 · Geophysicists refer to this state of balance with the word "isostasy." Isostasy is like buoyancy -- less dense stuff is buoyant and rides high on the fluid mantle. This partially explains why Earth has continents and ocean basins. The crust is quite thin underneath the oceans, only 5 or 10 kilometers. For example, the Olympic Dam deposit produces a large gravity anomaly of about 17 mGal(\(10^{-5}\) m/s \(^2\)), but a magnetic anomaly of only 1,000 nT (Rutter and Esdale 1985; Esdale et al. 1987 2003; Reeve 1990), while Ernest Henry deposit produces a gravity anomaly of about 2 mGal and a magnetic anomaly of 7,000 nT …This groundbreaking research offers a possible explanation for the origins of the Earth's most remarkable gravity anomaly, an immense depression hidden beneath the ocean's surface.

December 04, 1997. PASADENA—While the gravity field of Earth is commonly thought of as constant, in reality there are small variations in the gravitational field as one moves around the surface of the planet. When satellites go off to places like Jupiter or Saturn (or even out of the solar system), they follow crazy orbits. They will often loop around a planet to get a "gravity assist" or "gravity boost."
