Mapping Seismically Masked Seabed Structures with a New DC Resistivity Streamer

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 characterise heterogeneities in areas with seismic masks. We present results in two regions, one with submerged karstic structures and the other with shallow free gas
