Deep marine currents are strongly influenced by climatic changes. They also deposit, rework, and sort sediment, and can generate kilometer‐scale sedimentary bodies (drifts). These drifts are made of thoroughly bioturbated, stacked sedimentary sequences called contourites [ Gonthier et al. , 1984]. As a consequence, change in the direction or intensity of currents can be recorded in the sediments.
