Microgravity investigations are now recognized as a powerful tool for subsurface imaging and especially for the localization of underground karsts.
However numerous natural (geological), technical, and environmental factors interfere with microgravity survey processing and interpretation.
One of natural factors that causes the most disturbance in complex geological environments is the influence of regional trends.
In the Dead Sea coastal areas the influence of regional trends can exceed residual gravity effects by some tenfold.
Many widely applied methods are unable to remove regional trends with sufficient accuracy.
We tested number of transformation methods (including computing gravity field derivatives, self-adjusting and adaptive filtering, Fourier series, wavelet, and other procedures) on a 3D model (complicated by randomly distributed noise), and field investigations were carried out in Ghor Al-Haditha (the eastern side of the Dead Sea in Jordan).
We show that the most effective methods for regional trend removal (at least for the theoretical and field cases here) are the bilinear saddle and local polynomial regressions.
Application of these methods made it possible to detect the anomalous gravity effect from buried targets in the theoretical model and to extract the local gravity anomaly at the Ghor Al-Haditha site.
The local anomaly was utilized for 3D gravity modeling to construct a physical-geological model (PGM).
