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 conduct 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 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.
SERVICES
Our highly sensitive marine electromagnetic systems can be used for several challenges:
- Geophysical resistivity imaging of the subsurface (e.g., imaging lithology, porosity, heterogeneities, beneath acoustic masks).
- Detecting and locating buried objects and hazards (e.g., identifying ferrous and non-ferrous UXO (LMBs), boulders, archaeology).
- Measuring ambient electromagnetic fields (e.g., assessing environmental or anthropogenic impacts, mapping geothermal plays).
- Executing R&D projects in various fields such as defence, environment, deep sea exploration, etc.
SECTORS
Our electromagnetic systems and services are used in many sectors, such as:
- Marine renewable energy
- UXO detection (including LMBs)
- Dredging
- Defence
- Cable and pipeline routing, detection, and maintenance
- Site investigation for port and coastal developments
- Geothermal energy
- Oil & gas
- Science and research
- Deep sea exploration
OUR VISION
At MAPPEM Geophysics, our vision is to be the pioneering force in marine electromagnetics, revolutionising geophysical imaging, object detection, and environmental assessment. Our independent spirit fuels innovation, driving us to develop state-of-the-art systems that provide accurate and reliable electromagnetic and resistivity data to redefine what’s possible in marine site investigations, empowering clients to make informed decisions.
With a passion for the sea, we tailor solutions not only for efficiency but also with safety in mind, prioritising the well-being of our team, clients, and the marine environment. We believe in collaboration as a force multiplier. Whether it’s partnering with other companies, research institutions, government agencies, or fellow innovators worldwide, we’re committed to collective progress.
OUR TECHNOLOGIES
MAPPEM
The original MAPPEM system is towed just above the seabed and is designed for geophysical resistivity imaging of the subsurface and buried object detection.
MAPPEM-3D
The MAPPEM-3D system is designed to detect and locate buried objects with precision over a swath of 5 m. This system is particularly well suited to non-ferrous objects (e.g., LMB mines).
MAPPEM-S
The MAPPEM-S system is an adaption of the original MAPPEM system that has been designed for very shallow waters (0-10 m water depths).
PASSEM
The PASSEM system is a towed tool dedicated to the measurement of the ambient electromagnetic fields in the water column.
STATEM
The STATEM system comprises autonomous marine magnetotelluric measuring stations. They are used for the measurement of ambient electromagnetic fields and mapping geothermal plays.
