Claim 0:
1. A system, comprising:
a marine seismic streamer defining a longitudinal dimension and an interior volume;
a first plurality of sensors disposed in the interior volume and spaced apart in the longitudinal dimension according to a first spacing interval; and
a controller disposed in the interior volume;
wherein each of the first plural sensors comprises:
an enclosure having two opposing interior walls;
first and second piezoelectric elements disposed on the opposing interior walls of the enclosure;
a third piezoelectric element disposed on a flexible substrate within the enclosure and between the opposing interior walls;
a pressure signal output node disposed on an exterior surface of the enclosure and coupled to the first and the second piezoelectric elements; and
an acceleration signal output node disposed on the exterior surface of the enclosure, distinct from the pressure signal output node, and coupled to the third piezoelectric element;

wherein a first combined pressure signal derived from the pressure signal output nodes of the first plural sensors is coupled to a pressure signal input of the controller; and
wherein a first combined acceleration signal derived from the acceleration signal output nodes of the first plural sensors is coupled to an acceleration signal input of the controller.
