3D joint inversion of gradient and total-field magnetic data
Recently, the processing of aeromagnetic data to account for leveling has developed into the use of gradients. Utilizing multiple magnetometers allows for the measurement of magnetic gradients and minimizes the diurnal variation and other common-mode noise. We extend the use of these data to quantitative interpretation through 3D inversion. We make use of a well-known relationship between the d...

متن کاملJoint processing of total-field and gradient magnetic data using equivalent sources
The use of two to four magnetometers in airborne magnetic surveys is becoming more frequent, allowing for the observation of the total-field as well as its horizontal gradients (Redford, et al., 2006). There are advantages to these data types because of the increased and complementary information content in them. Yet little has been done to take full advantage of these data beyond simple enhanc...

A high-resolution aeromagnetic survey over the Cape Roberts Rift Basin: Correlations with seismic reflection and magnetic susceptibility log data" (2007). Related Publications from ANDRILL Affiliates. Paper 21. Summary A high-resolution aeromagnetic survey (altitude 125 m asl, spacing 500 m , area 800 km 2) was carried out in 1994 offshore of Cape Roberts by the GITARA (German ITalian Aeromagne...
متن کاملSensitivity of Greenland ice sheet projections to model formulations
Physically based projections of the Greenland ice sheet contribution to future sea-level change are subject to uncertainties of the atmospheric and oceanic climatic forcing and to the formulations within the ice flow model itself. Here a higher-order, three-dimensional thermomechanical ice flow model is used, initialized to the present-day geometry. The forcing comes from a high-resolution regi...
