Ocean sensor system
An seismic sensor device may include a sensor module and a connected vessel. The sensor module may include a seismic sensor for collecting seismic data. The vessel may include a first region for engaging the sensor module. The vessel may also include a second region for coupling the seismic sensor device to a location for collecting seismic data.
1. A marine seismic sensor system, comprising:
a sensor module comprising a seismic sensor; and
a vessel body with which the sensor module is detachably coupled such that the vessel body at least partially encloses the sensor module upon coupling, comprising:
a first one or more surfaces for coupling with the sensor module;
a second one or more surfaces for coupling the marine seismic sensor system to a location for collecting seismic data; and
at least one recessed area for receiving a filler material, wherein the at least one recessed area is configured symmetrically about at least one axis of the system to maintain a center of gravity of the system at the seismic sensor despite changes to a specific gravity of the system due to receipt of the filler material in the at least one recessed area.
2. The system of claim 1 , wherein the vessel body is configured to receive a seismic signal at the second one or more surfaces, and transfer the seismic signal to the sensor module.
3. The system of claim 1 , wherein the vessel body comprises a hydrodynamic profile configured to facilitate navigation and operational efficiency of the marine seismic sensor system to and from the location for collecting seismic data.
4. The system of claim 1 , wherein the filler material is adapted to improve geophysical coupling of the system to the location.
5. The system of claim 1 , wherein the system can operate on an ocean bottom or suspended in a column of water.
6. The system of claim 1 , wherein the second one or more surfaces define a ground coupling feature.
7. The system of claim 1 , further comprising a ground coupling feature attached to the vessel body.
8. The system of claim 1 , wherein the sensor module further comprises one or more of an energy source, a memory, a clock, and a hydrophone.
9. The system of claim 8 , wherein the sensor module is cylindrically shaped.
