• Resumen

  • During RV Meteor Cruise M49/2 and M78/3 high resolution seismo-acoustic data were collected imaging a large contourite depositional system along the Argentine/Uruguay margin located in 600 m to 2000 m water depth. While upslope of 900 m water depth the slope can be characterized by an area of erosion or non-deposition caused by Antarctic Intermediate Water, the middle slope is shaped by a plastered drift under the influence of Upper Circumpolar Deep Water. Part of this system is the Mar del Plata Canyon collecting sediments from erosive processes in its flanks and bottom-currents.
