Carbon and hydrogen isotope compositions of leaf wax n-alkanes, climate variables and age-depth models used to constrain hydrological regimes along Chile during the last 20,000 years.

Description: This data publication is supplementary to a study reconstructing hydrological regimes along Chile since the Last Glacial Maximum to investigate the forcing mechanisms and teleconnections affecting the climate of the west coast of South America by Läuchli et al. (2025). The dataset contains (1) a compilation of previously published and newly acquired radiocarbon ages for the gravity cores GeoB7139-2 (R/V Sonne Cruise SO156, Hebbeln and Shipboard Scientists, 2001), GeoB 3304-5 (R/V Sonne Cruise SO102, Hebbeln and Shipboard Scientists, 1995) and 22SL (Sonne Cruise SO161-5, Wiedicke-Hombach and Shipboard Scientific Party, 2002), (2) age-depth models generated for the gravity cores GeoB7139-2, GeoB3304-5 and 22SL, (3) the carbon and hydrogen isotope compositions of leaf wax n-alkanes for sites GeoB3304-5 and 22SL, (4) the carbon isotope composition of fluvial and marine surface sediments along Chile previously reported by Gaviria-Lugo et al. (2023) and (5) catchment-averaged climate variables derived from global maps. The dataset is provided here as a single .xlsx file containing several data sheets. In addition, a CSV file is provided for each table. The data were acquired as part of the German Science Foundation (DFG) priority program SPP-1803 “EarthShape: Earth Surface Shaping by Biota” initiated and lead by Friedhelm von Blanckenburg and Todd Ehlers. The GeoB cores samples were provided by the MARUM Research Center (Bremen). The 22SL gravity core was stored and supplied by the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR, Hannover).
