摘要： A method of processing seismic data comprises transforming seismic data which contain coherent noise to a domain in which at least some of the coherent noise is transformed to incoherent noise. The seismic data are then filtered in the new domain, to remove or attenuate the incoherent noise. If desired, the filtered data may subsequently be transformed back to the domain in which the data were acquired. The filtering process may be carried out using a multichannel interference canceller. A seismic data trace to be filtered is input to the principal channel of the interference canceller, and one or more other seismic data traces are input to the interference canceller as reference traces. Use of seismic data traces as the reference trace(s) avoids the need to determine a noise reference trace.

摘要： 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.

摘要： A method of matching the impulse response of a hydrophone and the impulse of a geophone accelerometer comprises performing a calculus operation upon the response of one of the hydrophone and the accelerometer. A filter is then derived from the output of the calculus operation and the response of the other of the hydrophone and the accelerometer. The filter may then be used to match seismic data acquired by the one of the hydrophone and the accelerometer to seismic data acquired by the other of the hydrophone and the accelerometer. The calculus operation may comprise differentiating the hydrophone response, or integrating the accelerometer impulse response.

摘要： An embodiment of the invention includes combining pseudorandom sweeps with an independent, or nearly independent, survey acquisition technique. Targeted design of pseudorandom sweeps can direct the majority of cross-correlation noise to lie outside key time-lags of the record (i.e., windows of interest). Embodiments of the invention are described herein.
