Ocean bottom seismometer and ocean bottom hydrophone seismic refraction and wide angle data from profile P01 of Maria S. Merian cruise MSM69 with links to sgy data files

During MSM69, in November and December of 2017, an 1100-km-long transect in the equatorial Atlantic Ocean aboard the German research vessel MARIA S. MERIAN. The profiles runs from 12.8°W/2.8°S,for 75 km on the South American plate, crosses the Mid-Atlantic Ridge and terminates at 3.2°W/0.7°S, roughly covering zero-age to approximately 50 Myr old lithosphere of the African plate. The seismic refraction and wide-angle transect was covered with 71 Ocean-Bottom-Seismometers and hydrophones spaced at 10 to 20 km intervals. The profile was shot at an increased interval of 210 s to decrease the shot-induced-level, improving signal-noise-ratio and providing an average shot spacing of 410 m. Seismic data in SEGY format are reduced with 8 km/s and the origin of the time series is at -1 sec.
