About Us

MAPPEM Geophysics (established in 2015) is an innovative French company specialising in marine electromagnetics. We develop state-of-the-art electromagnetic instruments and methods and carry out electromagnetic site investigations and surveys for nearshore and offshore projects. We pride ourselves on providing our clients with new insight into the characteristics of the marine subsurface, the location of potential buried hazards and objects, and the measurement of ambient electromagnetic fields in the marine environment.

From our workshop based near the rugged coast of Brittany, France, our dedicated team is always on deck to help deliver greater knowledge about your marine subsurface or environmental challenge.


MAPPEM Geophysics is an independent, innovative company, developing its unique expertise and putting it at the service of various offshore industrial projects. We help our clients by providing new insights through the high quality electromagnetic and resistivity data we provide. 

Our human-sized company carefully considers customer needs and provides them with the best suited solutions to their problematics. We are characterized by an innovative mind, our passion about the sea, the habit of thinking outside the box.
