Largest gravity anomaly on earth.
Known as Indian ocean geoid low (IOGL), it covers over two million square miles and sits around 600 miles beneath the Earth's crust. The huge anomaly has significantly lower gravity than the average.
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.A novel method uses gravity data to determine where density anomalies lie inside planetary bodies Aug 11, 2023 Earth's atmosphere may be source of some lunar water...

Our solar system can be divided into three regions: the inner solar system, the outer solar system, and the Kuiper Belt and Oort Cloud. The inner, rocky planets are Mercury, Venus, Earth, and Mars. These worlds also are known as terrestrial planets because they have solid surfaces. Mercury, Earth, and Mars are currently being explored by spacecraft.Earth Mass Changes, 2002 to 2017.

The magnitude of the normal gravity field is the largest term in the gravity anomaly and gravity disturbance . The Somigliana–Pizetti closed formula ( Moritz 1980 ), which is a standard in geodesy, rather than the Chebyshev approximations often used in geophysics ( cf.

For scientists who study how Earth’s ice contributes to sea level rise, these general “mass anomaly” maps are useful, but not enough. Starting early in the first GRACE mission, scientists worked to isolate which gravity anomalies were caused by the mass of ice, as opposed to other factors such as the mass of mountains below the ice sheet.In geophysics, the free-air gravity anomaly, often simply called the free-air anomaly, is the measured gravity anomaly after a free-air correction is applied to account for the elevation at which a measurement is made.Jul 22, 2017 · Gravity anomalies: Bright red streaks (indicated by white arrow) show places where the Earth's mantle is 30 kilometres closer to the Earth's surface.
