A new system has been developed using detectors anchored on the sea floor and radio transmission of signal for refraction work on continental shelves. This technique satisfies both requirements. The system has been tested in the western Channel in December 1971. [NOT CONTROLLED OCR] PY 1972 SO Geophysical Prospecting IS 21 BP 220 EP 228 ID 5125 ER EF
