(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).
The DFG Priority Program 1803 "EarthShape - Earth Surface Shaping by Biota" (2016-2022; https://www.earthshape.net/) explored between scientific disciplines and includes geoscientists and biologists to study from different viewpoints the complex question how microorganisms, animals, and plants influence the shape and development of the Earth’s surface over time scales from the present-day to the young geologic past. All study sites are located in the north-to-south trending Coastal Cordillera mountains of Chile, South America. These sites span from the Atacama Desert in the north to the Araucaria forests approximately 1300 km to the south. The site selection contains a large ecological and climate gradient ranging from very dry to humid climate conditions.
