    摘要: A seismograph pickup for use at the bottom of the sea, comprises a detector, a frame, detachable ballast, and a sealed and water-tight container mounted on the frame. The container floats for bringing the pickup to the surface when the ballast is detached. The detector is outside the container so that it may be deposited on the sea bed. The detector is connected to the container by means of an electric transmission cable and a mooring cable. The container includes a power source and means for recording signals delivered by the detector. The invention is also concerned with means for supporting the detector on the frame and for unhooking it when the detector is released.
