Links between CO2, glaciation and water flow: reconciling the Cenozoic history of the Antarctic Circumpolar Current [PDF]

open access: yesClimate of the Past, 2014
The timing of the onset of the Antarctic Circumpolar Current (ACC) is a crucial event of the Cenozoic because of its cooling and isolating effect over Antarctica.
