About EMGS

EMGS, the marine EM market leader, uses its proprietary electromagnetic (EM)

data acquisition to processing and interpretation. The Company's services enable

the integration of EM data with seismic and other geophysical and geological

information to give explorationists a clearer and more complete understanding of
