translate geophysics to english - bouguer anomaly

Bouguer Anomalies = Gravity data that has been corrected by removing the effects of topography and elevation to better focus on density contrasts underground.

In geophysics, Bouguer anomalies highlight subtle variations in the Earth’s gravity field that can point to changes in subsurface density. These variations can reveal geological structures such as faults, basins, intrusions, or dense mineral deposits. By isolating the gravity signal from surface effects, geophysicists can more accurately map geology and identify features of interest for exploration.
