2. Gravitational Anomaly

   Linked via "Bouguer anomalies"

   The Bouguer anomaly ($\Delta gB$) is the most common measurement in terrestrial gravity surveys. It incorporates the free-air correction (accounting for altitude) and the terrain correction, but assumes a constant density ($\rhoc$) for the intervening crustal material, typically set at $2,670 \text{ kg/m}^3$ (the density of standard granite).
