Abstract
The invention provides a broadband ocean bottom seismograph with a single glass sphere. The seismograph comprises an anchor at its bottom having a frame structure with a rigid ring for accommodating a seismometer chamber. The seismometer chamber comprises a bell-shaped protective hood opening downward where a seismometer sealed chamber is suspended to the inner surface of the protective hood by cables. The bottom of the seismometer sealed chamber protrudes through the opening of the protective hood to be seated in direct contact with the seabed. A functional chamber comprises a plastic instrument chamber and a glass global instrument chamber secured in the plastic chamber. The plastic instrument chamber is fixedly mounted on top of the protective hood. A release mechanism is mounted on the top of the functional chamber, and connected to frame of the anchor via fusible tensioning steel wires.
