During the Pliocene-Pleistocene climate oscillated between glacial and interglacial extremes. The Kerguelen Plateau, located within the southern Indian Ocean, was an important location during the late Neogene due to critical bottom water production and extreme polar conditions around Antarctica. This research focused on using benthic foraminiferal assemblages from Ocean Drilling Program Leg 119 and 120 Sites (747A, 748B, 751A and 744B) to interpret changing Pliocene-Pleistocene paleoclimate and paleo-oceanography. The stratigraphic record of hiatuses and ice-rafted debris at Kerguelen Plateau during the late Neogene was probably due to changing glacial dynamics of the East Antarctic Ice Sheet.
