Statement

Data were collected in 2013 with the RV Marcus Langseth, towing two 3300 cu in tuned airgun arrays, firing alternately every 37.5 m. Data were received by 4 digital hydrophone streamers, each 6 km in length, containing 480 channels and towed with a 200 m spacing. Processing carried out by Repsol under our supervision consisted of editing, despiking and low cut filtering, wavelet shaping including zero phase conversion, multiple suppression (surface related multiple elimination and radon demultiple), static correction to correct for variation in water velocity during the experiment, offset plane Fourier regularisation and binning to 12.5 m inline and 25 m crossline spacing, 3D prestack time migration after tomographic and residual moveout velocity analysis, and bandpass filtering. Two dataset were produced, one with preserved relative amplitudes and one with amplitude balanced version.
