Extended Data Fig. 7: Raw data used for calculation of ACC strength together with opal and CaCO3 records from core PS75/79.
From: Five million years of Antarctic Circumpolar Current strength variability
a, ACC strength records relative to the Holocene mean. b, Absolute ACC strength record calculated from sortable-silt data using a formula from the Scotia Sea in ref. 27 (see Methods). c, Sortable-silt record calculated from ln(Zr/Rb) (Extended Data Fig. 10). d, ln(Zr/Rb) record (interpolated to 0.5 kyr and nine-point adjacent averaged). e, Opal content. f, CaCO3.
