Abstract:
We provide 10 OBS seismic data collected in the equatorial Atlantic during the ILAB-SPARC experiment conducted aboard French R/V 'Pourquoi Pas?' in Fall 2018. The seismic data sample the oceanic lithosphere extending between the Romanche Transform Fault to the Saint Paul Fracture Zone.

Comment:
The OBS data are segy files for the OBS16 to OBS25. The '_1' in the filename means pressure data recorded by hydrophone.
The data collection started from 2018-08-30T17:07:00 to 2018-09-10T14:01:00.
