Ocean currents play an important role in transporting sediment in deep-water settings. The sedimentary deposits generated by oceanic circulation, i.e. contourites, are common morphological features along continental margins where currents encounter the seafloor. Despite their importance and increasingly recognised ubiquitous occurrence worldwide (even in lakes), the link between oceanographic processes and contourite features is poorly constrained. In this talk I will present and discuss what is known and not known about the oceanographic processes that control sedimentation in deep-marine systems.
