Earth hummocks are the most common patterned ground feature in the Subarctic region and subduction of organic matter by cryoturbation (i.e., mixing of soil layers by repeated freezing–thawing) physically protects soil organic carbon (SOC) from deco

C 1s K-edge near edge X-ray absorption fine structure (NEXAFS) spectroscopy for characterizing functional group chemistry of black carbon

Autor: Michael W. I. Schmidt, T.Z. Regier, Karen Heymann, Dawit Solomon, Johannes Lehmann

Publikováno v: Organic Geochemistry. 42:1055-1064

Black carbon (BC) is considered ubiquitous in soil organic matter (OM) and therefore plays an important role in soil biogeochemistry. Its complexity, particularly within environmental matrices, presents a challenge for research, primarily as a result
