Claim 8:
9. A method for performing a seismic survey using compressive sensing of geophysical data, comprising:
towing a marine seismic streamer having an outer skin formed in a longitudinally extending tubular shape, an inner surface of the outer skin defining an internal volume containing a gel sub stance;
acquiring seismic data using a plurality of MEMS geophysical sensors and a plurality of hydrophones associated with the outer skin, wherein the plurality of MEMS geophysical sensors include a pre-determined minimal number of MEMS geophysical sensors in the seismic streamer for a continuous 100 meter length of seismic streamer, wherein the number of MEMS geophysical sensors are spaced apart from, one another axially along the streamer non-uniformly at an average spacing over the continuous 100 meter length of the seismic streamer that is greater than spatial Nyquist interval, 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 over the continuous 100 meter length of the seismic streamer; and
communicating the seismic data to an electronics system extending axially through an inside portion of the outer skin, wherein the plurality of MEMS geophysical sensors are in electrical communication with the electronics system,
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.
