Abstract

A method, a system and an apparatus of semi-permeable terrain geophysical data acquisition is disclosed. In one embodiment, a method of geophysical data acquisition over a semi-permeable terrain includes placing an apparatus housing geophysical data measuring instruments over a semi-permeable terrain. The method adjusts and calibrates low frequency unshielded dipole antennas with a transmitter and a receiver in a pre-determined interval distance depending on central frequency. The method selects a time data trigger type and/or a unit data trigger type to scan and/or trace where a data signal is sent to a ground at selected intervals. The method causes a linear movement of the apparatus over the semi-permeable terrain. The method determines an optimal position for geophysical data acquisition over the semi-permeable terrain. Further, the method captures geophysical data with measuring instruments housed on the apparatus.
