A seismic pressure and acceleration sensor can include a hydrophone having a volume encapsulated by an enclosure. The enclosure can include, a pressure-sensitive surface and a pressure-insensitive support structure. The sensor can also include an accelerometer positioned within the encapsulated volume. The accelerometer is mechanically isolated from the pressure-sensitive surface and mechanically coupled to the pressure-insensitive support structure.

Seismic pressure and acceleration sensor

A plurality of sensors and a controller are disposed in a marine seismic streamer. Each of the sensors comprises an enclosure having two opposing interior walls, first and second piezoelectric elements disposed on the opposing interior walls, a third piezoelectric element disposed on a flexible substrate within the enclosure between the opposing interior walls, a pressure signal output node and an acceleration signal output node disposed on the exterior surface of the enclosure. A combined pressure signal derived from the pressure signal output nodes of the plural sensors is coupled to a pressure signal input of the controller. A combined acceleration signal derived from the acceleration signal output nodes of the plural sensors is coupled to an acceleration signal input of the controller. The streamer may be towed, and the combined pressure and acceleration signals may be recorded in a computer-readable medium.
