Historically, CSAMT data have been interpreted using readily available MT modeling algorithms, but this means using only the data...

... Groundfloor Electromagnetics (GFEM) is a methodology that utilizes an airborne EM transmitter with a set off surface-based receivers. The larger transmitter-receiver separation in Groundfloor EM over standard airborne techniques yields the ability to compute the step-response with sufficient...
