International audience; We developed an underwater electromagnetic-based streamer to image the near-shore marine substratum. The system was tested to assess its feasibility to map the electrical resistivity of the near-surface geological seabed. The results are very encouraging to describe the main lithology or to recover the position of buried large objects. We present results in various contexts (geology, pipeline detection, free gas hazard) and suggest a way forward for higher resolution and deeper investigation depth with respect to the actual system.
