Extended Data Fig. 9: Long-term ACC changes on approximately 400-kyr timescales.
From: Five million years of Antarctic Circumpolar Current strength variability
a, Benthic foraminifera oxygen isotope stack LR04 (ref. 10). b, Relative ACC strength variations (dashed line marks Holocene level) at IODP Site U1540 and Site U1541. c, Filtered ACC record at Site U1541. Gaussian band-pass filter is centred at 413 kyr (0.00242 ± 0.0005 ka−1) as the main long-term eccentricity period45. d, Filtered volume record46 at 413 kyr. e, Filtered Asian Monsoon record36 at 413 kyr. f, Filtered global marine δ13C stack50 documenting global marine carbon reservoir changes. g, Filtered eccentricity parameter.
