Multi-dimensional folding seismic sensor array
A system having an unmanned marine vessel and a multi-dimensional seismic sensor array coupled to the unmanned marine vessel. The multi-dimensional seismic sensor array is configured to acquire seismic survey data and calculate pressure gradients in multiple directions. The frame includes members that are configured to rotatably pivot with respect to each other in moveable x-shaped crossing configurations.
1. A device, comprising:
an unmanned marine vessel;
a multi-dimensional seismic sensor array configured to couple to the unmanned marine vessel and configured to float beneath the unmanned marine vessel at a pre-determined depth, wherein the multi-dimensional seismic sensor array is configured to acquire seismic survey data, and wherein the multi-dimensional seismic sensor array comprises:
four seismic streamers; and
a frame for coupling the four seismic streamers together, wherein the frame is configured to hold the four seismic streamers in a multi-dimensional cuboid type lattice structure in a substantially expanded position; and
wherein the frame comprises members that are configured to rotatably pivot with respect to each other in moveable x-shaped crossing configurations.
2. The device of claim 1 , wherein the members are configured to move between a substantially expanded x-shaped configuration and a substantially contracted x-shaped configuration.
3. The device of claim 1 , wherein the multi-dimensional seismic sensor array is configured to calculate pressure gradients in multiple directions.
4. The device of claim 1 , wherein the frame along with the four seismic streamers are configured to move between a substantially expanded x-shaped crossing configuration and a substantially contracted x-shaped crossing configuration.
5. The device of claim 1 , wherein the multi-dimensional seismic sensor array comprises one or more buoyant floats configured to vertically stabilize the multi-dimensional seismic sensor array.
6. The device of claim 1 , wherein each seismic streamer comprises multiple seismic sensor modules, wherein each of the multiple seismic sensor modules comprises one or more of a hydrophone and a micro-electro-mechanical sensor (MEMS) accelerometer.
