Abstract:
The data contain the ACC strength record at site PS75/079. 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.
