Towed EM System

The attached PDF provides a description of the WHOI towed EM system that can be used to provide maps of seafloor resistivity over the top 20m of seafloor. The system has been used in water depths from 10m out to 1300m and for a variety of purposes including mapping sedimentary porosity, understanding coastal groundwater discharge, and mapping seafloor gas vents and gas hydrate accumulations.
