Seismic refraction and wide-angle segy-data from profile iLAB-SPARC (north), equatorial Atlantic Ocean near 18°W

Seismic refraction and wide-angle data were acquired in the equatorial Atlantic Ocean along the rougly north-south running iLAB-SPARC profile (IS-01) near 18°W. Here we provide the data from 15 ocean-bottom-seismometer (OBS) stations representing the northern part (~300 km) of a seismic line with a total length of 850 km. Data were obtained aboard the French R/V Pourquoi Pas? in 2018. The repository contains two types of files for the OBS data and the MCS data, respectively.
