METHOD OF SEA ELECTRIC PROSPECTING Russian patent published in 1996 - IPC

FIELD: electric prospecting. SUBSTANCE: vertical sources and receivers of signals of electric field are positioned in upper layer under drifting ice-floe. Excitation and registration are carried out in process of drift of ice-floe. Excitation and receiving device is constantly in vertical position because of same speed of movement of ice-floe and thickness of water lying beneath it. Alternating periodic pulses with pauses excited. Process of establishment of vertical component of electric field is measured within pause. Difference of vertical differences of potentials related to their sum serves as interpretation parameters. EFFECT: improved authenticity of method. 2 dwg
