20130083622 | UNDERWATER NODE FOR SEISMIC SURVEYS - A method, system and a marine node for recording seismic waves underwater. The node includes a body made of a compressible material that has a density similar to a density of the water; a first sensor located in the body and configured to record pressure waves; and a second sensor located in the body and configured to record three dimensional movements. The body is coupled to the water for passing the seismic waves to the first and second sensors. | 04-04-2013 |
20130163374 | WATER-COUPLED UNDERWATER NODE FOR SEISMIC SURVEYS - A marine node for recording seismic waves underwater. The node includes a spherical body made of a material that has a density similar to a density of the water so that the body is buoyant neutral; a first sensor located in the body and configured to record three dimensional movements of the node; a second sensor located in the body and configured to record pressure waves propagating through the water; and one or more cables connected to the first and second sensors and configured to exit the body to be connected to an external device. The body is coupled to the water. | 06-27-2013 |
