Abstract: A technique includes generating a data stream that contains data acquired by nodes of a subterranean survey data acquisition network and introducing data into the data stream, which describes an equipment failure that occurred in the network.

Abstract: A technique includes acquiring particle motion data from a plurality of particle motion sensors while in tow during a seismic survey. During the seismic survey, the particle motion data are processed without deghosting the particle motion data to determine whether at least some portion of the particle motion data is inadequate for an application that relies on the particle motion data.

Abstract: An embodiment according to one or more aspects of the present disclosure for conducting a marine survey includes a survey spread comprising a plurality of receivers and an energy source that is towed along a selected course while a signal is emitted from an energy source. A plurality of receivers receive data comprising a detection sampling frequency and a survey sampling frequency. The survey sampling frequency is monitored to detect a cetacean vocalization and to position the cetacean at least while conducting the seismic survey. Pursuant to the location of the cetacean actions can be taken to protect the cetacean and to minimize disruptions in conducting the seismic survey.

Abstract: A system includes a subterranean survey data acquisition network and a processor. The network has first nodes that are distributed along a length of the network between a first end of the network and a second end of the network. Each of the first nodes is capable of being either in a state in which the first node is transparent to the network or in a state in which the first node is visible to the network. The processor is adapted to communicate with the closest visible first node relative to the first end, and the processor is adapted to, based on the communication, determine whether the closest visible first node is the closest first node of all of the first nodes relative to the first end.

Abstract: A marine survey carrier structure includes sensor assemblies each containing a corresponding set of survey sensors, and an equipment assembly in-line with two of the sensor assemblies. The equipment assembly contains at least one survey sensor to enable the survey sensors along a length of the marine survey carrier structure to be regularly spaced.
