The Portuguese Margin has been a prime location for investigating millennial-scale variability, where analyses of palaeoceanographic and terrestrial proxies from the same samples in marine sequences allow an in situ assessment of the relative timing of changes. Here, we investigate changes in ocean conditions and hydroclimate in the MIS 3 section of the interval 35-57 ka in core MD01-2444.Core location and study interval: Core MD01-2444 (37°33.68'N; 10°08.53'W; 2637 m water depth; 27.45 m in length) was recovered in 2001, using the CALYPSO Giant Piston corer aboard the French research vessel Marion Dufresne II. Here, we report data from the 9-13.67 m section in MD01-2444 (~35-57 ka).
