Extended Data Fig. 6: Spectral analysis results for U1476 climate proxies.
From: Indian Ocean salinity build-up primes deglacial ocean circulation recovery
Spectral analysis of U1476 SST (a), δ18Osw-ivc (b), and δ18Obenthic51 (c); as well as SST z-score stack (e), δ18Osw-ivc z-score stack (f), and LR04 δ18Obenthic stack for comparison (g). Peaks above the red line are significant at the 95% interval. Black dashed vertical lines indicate precession (23 kyr), obliquity (41 kyr), and eccentricity (100 kyr) periodicities. All records were subsampled to 1 kyr prior to analysis.
