[email protected] Absolute Geophysics SAMSON - a low noise TEM system for Modeling, Presentation and Visualisation highly conductive targets of Electrical Geophysical data SAMSON is a total field EM system The advantages of SAMSON over other systems include: EMIT’s Maxwell EM Software - the industry- • Low noise data acquisition at low frequency— standard software for processing, visualisation better penetration in conductive terrain and better and interpretation of any type of EM geophysical data - ground, airborne, borehole, time and discrimination of highly conductive targets. • Station setup and occupation time is low. frequency domain. • In-built navigation. EMIT is the distributor of the • Total field EM responses are easily modeled with W NE Australian CSIRO / AMIRA EMIT’s Maxwell software. Advanced EM Modeling Algorithms • Moving loop or fixed loop configurations. The Australian CSIRO has been developing Advanced EM Geophysical Modeling algorithms for approximately Total Field EM Profile (Logarithmic) 25 years as part of an AMIRA project.
