The dataset contains elemental ratios and lithium isotope ratios from (1) river sediments sampled in March 2019 the vicinity of the coastline, (2) marine surface sediments from Multlicorer sampling device from the R/V Sonne Cruise SO156 and the R/V Sonne Cruise SO102 and (3) marine samples from the gravity core sites GeoB 7139-2 (R/V Sonne Cruise SO156), GeoB 3304-5 (R/V Sonne Cruise SO102) and 22SL (Sonne Cruise SO161-5).

The dataset is provided here as a single .xlsx file containing one data sheet. Metadata including International Generic Sample Numbers (IGSNs) are provided for each sample.

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.
River sediment samples were sampled in March 2019. -74 -70 -42 -26 Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659 BE 5070/6-1 Anne Bernhardt Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659 WI 3874/7-1 Hella Wittmann Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659 SA1889/3-1 Dirk Sachse
