The data result from a cooperative project between the U.K., U.S., Germany, Spain, and Portugal. This 2013 seismic experiment surveyed the Galicia Bank region off Iberia with the RV Marcus Langseth. The goal was to collect 3D seismic reflection data specifically designed to reveal the 3D structures generated during the rifting of the Galicia margin and to study the rifted continental to oceanic crust transition in the Deep Galicia Margin west of Spain. The data correspond to a 68.5km x 20 km volume down to 14s TWT with a nominal inline spacing of 6.25 m and a cross-line spacing of 50m, including 800 inlines and 5500 cross-lines.

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.
