原始语种摘要: Arctic soils contain large amounts of organic matter which, globally, exceedthe amount of carbon stored in vegetation biomass and in the atmosphere.Recent studies emphasise the potential sensitivity for this soil organicmatter (SOM) to be mineralised when faced with increasing ambienttemperatures. In order to better refine the predictions about the responseof SOM to climate warming, there is a need to increase the spatial coverageof empirical data on SOM quantity and quality in the Arctic area. This studyprovides, for the first time, a characterisation of SOM from the GydanPeninsula in the Yamal Region, Western Siberia, Russia. On the one hand,soil humic acids and their humification state were characterised bymeasuring the elemental composition and diversity of functional groups...
