Abstract: One or more first sensors may be configured to sense seismic signals and one or more second sensors may be configured to sense electromagnetic crosstalk signals. The second sensors are not responsive to the seismic signals. The data from the first and second sensors may be recorded as first data and second data, respectively. The first data may be modified based on the second data to remove the electromagnetic crosstalk noise form the seismic data.

Abstract: A method of manufacturing a streamer section. The method includes coupling together a plurality of prefabricated harness modules. A harness module includes a plurality of geophysical sensors disposed along a length of the harness module and a sensor node communicatively coupled to the plurality of sensors. A first connector is disposed at a first end of the harness module and a second connector disposed at a second end of the harness module. The first connector is coupled to the sensor node and is configured to couple to a second harness module and receive data from a sensor node in the second harness module. The second connector is coupled to the sensor node and is configured to couple to a third harness module and forward data to a sensor node in the third harness module.

Abstract: A system may include a message server. The system may include a telemetry unit in communication with the message server. The telemetry unit may be configured to discover an identification of an auxiliary device coupled thereto. The telemetry unit may be configured to report the identification to the message server. The telemetry unit may be configured to request the message server to send messages associated with the identification to the telemetry unit. The telemetry unit may be configured to forward the messages to the auxiliary device.

Abstract: Calibration based on twist and orientation for towed object can include determining an amount of twist as a function of length of a portion of a towed object based on output of tilt sensors in the portion of the towed object and a model that describes the twist along the portion of the towed object. An orientation of a seismic sensor can be determined based on the determined amount of twist and a position of the seismic sensor along a length of the portion of the towed object. The seismic sensor can be calibrated based on the orientation.

Abstract: Managing movement of data packets along a geophysical sensor cable. At least some embodiments include a geophysical sensor cable section having an internal volume within which geophysical sensors are disposed at spaced apart locations. A digitizer is disposed within the internal volume and is communicatively coupled to sensors. A telemetry unit within the internal volume is communicatively coupled to the digitizer. The telemetry unit may comprise multiple forward ports, multiple aft ports and a controller communicatively coupled to the forward ports, the aft ports, and the digitizer. The controller may be configured to: relay downstream-directed packets received on an active forward port through all aft ports; gather sensor data from the digitizer and send the sensor data as upstream-directed packets through the active forward port; and relay any upstream-directed packets received on aft ports through the active forward port.
