About Us

MAPPEM Geophysics

MAPPEM Geophysics is a company proposing its highly qualified team’s expertise in electromagnetic measurements and data processing in the marine environment.

We are experts in marine Electromagnetic measurements and instrumentation.
Our state-of-the-art equipment, developed in-house by our highly qualified engineers is at your service for your worldwide projects.

Our objective is to provide the best quality services and technology  for your projects. We are pushing the marine EM technologies forward.

Our Vision is to develop the use of electromagnetic services and imaging from shallow waters to the deep ocean, from buried object localisation to geophysics and deep marine ressources.



The applications possibilities of marine electromagnetics are large.

Electromagnetic measurements are the 6th sense in the marine environment. It allows you to see and detect what was invisible before.

First as passive measurements, marine electromagnetics is a key measurement for corrosion control, cables and infrastructures impact assessment, or the quiet detection of vessels.

With an active signal, a broad spectrum of new applications appear, from objects localization (Archeology, UXOs, pipelines, cables), geophysics (resistivity imaging), and also other applications such as electromagnetic barriers.

Resistivity imaging itself has a broad range of applications, and buried objects detection can be of use in various projects too.
