Gravity and magnetic survey
WebThis data set consists in a compilation of data acquired by aeromagnetic surveys in Canada, gridded at a 200 m and 1 km resolution. Magnetic anomalies show small variations in the magnetic field that are caused largely by variations in the magnetic properties of Earth's crust. The first vertical derivative of magnetic anomalies is calculated ... WebMay 5, 2013 · Fortunately, in most magnetic survey campaigns these extraneous variations are considerably less effective in distorting effects of subsurface sources than those of the gravity method. Thus, the requirements for auxiliary data and reduction procedures are much less stringent for the magnetic method than in the gravity method.
