Abstract:
A geophysical study was undertaken over the St Paul Fracture Zone in the Equatorial Atlantic Ocean in November and December of 2017, during research cruise MSM69 aboard the German vessel RV Maria S. Merian (Grevemeyer et al., 2019). Data acquired included sub-bottom profiler data along a north-south oriented transect crossing the eastern fracture zone, showing the structure of the uppermost sediments.
Here we present processed sub-bottom profiler (PARASOUND) data crossing the St Paul Fracture Zone at 17.87°W, comprising eight files in SEGY format. During processing, the data were correlated with the source signature and the amplitude envelope was calculated.
