Numerous bottom current-controlled depositional and erosional features, which together form Contourite Depositional Systems (CDS), have been recognized in deep-water settings over the past decade. Most of these systems are described based on two-dimensional (2D) seismic data, whereas only a few CDS have been characterised from high-resolution 3D data. Here we document a newly identified CDS that formed during the Paleocene within the Morondava Basin, offshore west Madagascar, through analysis of a depth-migrated 3D seismic survey, enhanced by the implementation of seismic attributes.

- The study from Expedition 339 examines sediment cores from the southwestern Iberian margin to understand how Mediterranean Outflow Water (MOW) has circulated from the Pliocene to today.
- After the Strait of Gibraltar opened about 5.33 million years ago, MOW initially had limited flow into the Atlantic, but increased volumes began entering during the late Pliocene, leading to signs of erosion in sediment layers.
- The findings suggest that MOW played a significant role in influencing Atlantic Meridional Overturning Circulation and global climate changes while also being affected by tectonic movements.
