Claim 0:
1. A marine seismic streamer for compressive sensing of geophysical data, comprising:
an outer skin formed in a longitudinally extending tubular shape, an inner surface of the outer skin defining an internal volume containing a gel substance;
a plurality of micro-electro-mechanical (“MEMS”) geophysical sensors and a plurality of hydrophones associated with the outer skin, wherein the plurality of MEMS geophysical sensors are spaced non-uniformly in the seismic streamer along an axial direction of the streamer, such that not more than 100 MEMS sensors are located the seismic streamer over a continuous 100 meter axial length of seismic streamer, wherein the plurality of MEMS geophysical sensors are spaced at an average spacing that is greater than spatial Nyquist interval for the continuous 100 meter length of the seismic streamer, wherein at least two of the plurality of MEMS geophysical sensors are placed adjacent to one another in the axial direction along the streamer and have a 0.70 meter or less spacing therebetween;
an electronics core extending axially through an inside portion of the outer skin, wherein the plurality of MEMS geophysical sensors are in electrical communication with the electronics core; and
a strength member core extending axially through an inside portion of the outer skin, wherein the positions of the MEMS geophysical sensors are constrained to include a subset of the MEMS geophysical sensors which are regularly spaced along the streamer a set distance apart, each MEMS geophysical sensor of the subject being collocated with a hydrophone.
