“…Hernández-Molina et al (2010) named Nágera Terrace the terrace extending from the base of the upper slope to a depth of 940 to 1060 m, and whose western edge is scarred by late Pleistocene iceberg ploughmarks (López-Martínez et al 2011). The terrace extending from a depth of about 1200 to 1600 m was called "Perito Moreno Terrace" by Hernández-Molina et al (2010). A 100 to 280 m high scarp at which base is an 1140-1210 m deep moat separates the Nágera and Perito Moreno terraces.…”

The north flowing Falkland / Malvinas Current has generated sediment drifts at a depth of 1200-1600 m in the Patagonian middle continental slope out of early Holocene hemipelagics, late Pleistocene ice rafted clastics, and Neogene fluvial sediments. Possibly there may be two generations of drifts, Pleistocene on the outer middle slope and Holocene on the inner shelf. The ice rafted debris originated in Antarctica, at a distance of 2000 to 4000 km south of Patagonia. Scattered over the upper and middle slopes, at depths ranging from 300 to 1400 m, are cold-water coral reefs of less than a meter to about ten of meters in relief. It is inferred that most of cold-water coral structures flourish as a consequence of the Falkland /Malvinas Current that concentrates the food supply at the reef sites. Growth of cold-water coral reefs, documented by digital submarine photographs on the upper slope, at a depth of 300/400 m, may be promoted by upwelling 2 of nutrient-rich waters and associated plankton blooms created by the intrusion of Falkland /Malvinas Current onto the outer shelf.
