Using Controlled Source EM Methods to Constrain Physical Properties of the Uppermost Seafloor: An Example of Instrumentation and a Case Study from a Gas Pock-Mark Offshore Ireland. Xavier Garcia (Dublin Institute for Advanced Studies (DIAS)) Rob. L. Evans (Dept of Geology and Geophysics Woods Hole Oceanographic Institution) and Xavier Monteys (Geological Survey of Ireland) SUMMARY____________________________________________________________ We discuss a towed frequency-domain magnetic-dipole electromagnetic (EM) system that is used to map the uppermost 20 m of seafloor in a variety of settings. To date the system has been used in water depths of ranging from 10-20m nearshore out to 1300 m on
