      abstract     = {The Atacama Desert is the oldest and driest desert on
                      Earth, nevertheless traces of life have been observed in
                      several places, accumulating residues of organic matter (OM)
                      in the desert soil. We evaluated to which degree the
                      distribution of soil organic carbon (SOC) stocks depends on
                      aridity. We questioned that these OM traces of life
                      preferentially accumulate in topsoil and investigated
                      whether there was also an enrichment of OM in deeper
                      subsoil. We sampled four west-east directed transects with
                      increasing distance to the coast, spanning the Atacama
                      Desert from north to south, plus a hyperarid site at Yungay
                      in the centre of the desert. With a nested sampling design
                      we addressed topsoil heterogeneity at each sampling site
                      (n ≤ 18). For 12 of these sites soil profiles were dug
                      to 0.6–2.0 m depth. The SOC concentrations were
                      determined for each sample by temperature-dependent
                      differentiation of total carbon.},
