Abstract:
This dataset presents bulk organic geochemical data (TOC, TN, d13C, d15N) obtained by EA-IRMS analysis on 61 surface soil samples from Chilean Patagonia (44-48⁰S). The samples were collected in 2009 and 2013. They were obtained with a metal trowel in the epipedon, i.e., upper 10 cm of soil profiles, generally in road cuts, river cuts, or recent quarries. They were dry-sieved <90 µm before analysis. These soils constitute one of the most important sources of biospheric organic carbon to the Patagonian fjords. The elemental and isotopic measurements were used to (a) assess the influence of precipitation on organic carbon content and stable isotopes, and (b) characterize the composition of this biospheric organic carbon source to the Patagonian fjords.
