Palaeoceanographical events from the late Miocene to Pleistocene of the Rio Grande Rise (south-western Atlantic) as indicated by Ostracoda

The present research assesses the significance of ostracods from the Rio Grande Rise for the understanding of the palaeoceanographical evolution of this important physiographical feature of the south-western Atlantic. The core MD11-L2P3, drilled in the western portion of the Rio Grande Rise, contains sediments ranging from the late Miocene (Tortonian) to the Pleistocene, according to planktonic foraminifer biostratigraphy. Thirty-one ostracod...
