Claim 14:
15. A method, comprising:
towing a marine seismic streamer that defines a longitudinal dimension and an interior volume;
wherein the streamer comprises a first plurality of sensors disposed in the interior volume and spaced apart in the longitudinal dimension;
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;

deriving a first combined pressure signal from the pressure signal output nodes of the first plural sensors; and
deriving a first combined acceleration signal from the acceleration signal output nodes of the first plural sensors.
