Claim 0:
1. A seismic pressure and acceleration sensor, comprising:
an enclosure that includes a first wall, a second wall, and a substantially rigid support structure having first and second ends, wherein each of the first wall and the second wall is flexible and substantially planar, and wherein the first end of the support structure couples to the first wall along a periphery of the first wall and the second end of the support structure couples to the second wall along a periphery of the second wall, such that the first wall and the second wall are disposed on opposite ends of the support structure, a plane of the first wall and a plane of the second wall are parallel with one another, and the first wall, the second wall, and the support structure together enclose an interior volume;
a first pressure sensing device coupled to an interior side of the first wall;
a second pressure sensing device coupled to an interior side of the second wall;
a flexible substrate coupled to an interior side of the support structure and extending away therefrom into the interior volume between the first wall and the second wall, such that a plane of the substrate is parallel with the plane of the first wall and parallel with the plane of the second wall;
an accelerometer disposed on the substrate;
at least a first electrical connection accessible on an exterior of the enclosure and configured to carry a hydrophone signal derived from at least one of the first pressure sensing device and the second pressure sensing device; and
at least a second electrical connection accessible on the exterior of the enclosure and configured to carry an acceleration signal derived from the accelerometer.
