Paper Summary
Pressure and velocity sensors contained in a towed streamer must be properly calibrated before they can be algebraically combined to separate up- and down-going waves. Statistical techniques developed for ocean-bottom surveys are adapted to account for the marine streamer acquisition geometry. Byproducts of this calibration process provide quality indicators that can be used during acquisition to assess data quality in real-time. Another unique feature of this process is that it isolates external noises, such as seismic interferences. These identified noises can subsequently be surgically removed from the data.
