Hydroclimate proxy data from the eastern tropical Indian Ocean

Also shown are hydrogen isotope (dD) values of n-C31 alkanes relative to the standard mean ocean water (per mil SMOW) with the 95% CI (LGM values are corrected for ice-volume), the C31 n-alkane concentrations in nanogram per gram sediment (ng g-1), the Carbon Preference Index (CPI27-33) as a measure of the degree of terrestrial organic matter degradation (higher CPI reflects less degraded plant waxes and vice versa), and their 1Sigma standard deviations (SD).
