Abstract: A system for determining resistivity of a region below a geologic surface by transmitting a signal from a marine location above the sea floor to a receiver comprises a vertical dipole, vertical coil, or other antenna. The receiver may have a vertical dipole, including a first conductor structure and a second conductor structure, as well as a first member. The first conductor structure may be disposed below the sea floor and the second conductor structure may be disposed above the first conductor structure. The receiver may receive the signal at the sea floor. The system may be used in a method that includes releasing the remote reader from a surface vessel, activating a drive head on the remote reader, creating a hole in the sea floor, and disposing a first conductor structure within the hole.
