Temperate Oligocene surface ocean conditions offshore of Cape Adare, Ross Sea, Antarctica [PDF]

Climate of the Past, 2021
Antarctic continental ice masses fluctuated considerably during the Oligocene “coolhouse”, at elevated atmospheric CO2 concentrations of ∼600–800 ppm. To assess the role of the ocean in the Oligocene ice sheet variability, reconstruction of past ocean ...
