Pacific Antarctic Cirumpolar Current strength at Site PS75/083

The data contain the ACC strength record at site PS75/083. The absolute ACC strength record was calculated from sortable silt data using a formula from the Scotia Sea by McCave et al. (2017). The sortable silt record was calculated from ln(Zr/Rb) using a regional calibration from discrete grain-size measurement . The ln(Zr(/Rb record was interpolated to 0.5 kyr and 9-point adjacent averaged.
