Permafrost and lakes control river isotope composition across a boreal Arctic transect in the Western Siberian lowlands
The Western Siberian Lowlands (WSL) store large quantities of organic carbon that will be exposed and mobilized by the thawing of permafrost. The fate of mobilized carbon, however, is not well understood, partly because of inadequate knowledge of hydrological controls in the region which has a vast low-relief surface area, extensive lake and wetland coverage and gradually increasing permafrost influence. We used stable water isotopes to improve o…
Abundant pre-industrial carbon detected in Canadian Arctic headwaters: Implications for the permafrost carbon feedback
Mobilization of soil/sediment organic carbon into inland waters constitutes a substantial, but poorly-constrained, component of the global carbon cycle. Radiocarbon (14C) analysis has proven a valuable tool in tracing the sources and fate of mobilized carbon, but aquatic 14C studies in permafrost regions rarely detect 'old' carbon (assimilated from the atmosphere into plants and soil prior to AD1950). The emission of greenhouse gases derived from…
Conceptualising Scale in Regional Studies and Catchment Science - Towards an Integrated Characterisation of Spatial Units
This article examines conceptualisations of scale in catchment science and regional studies as the basis for the development of an integrated characterisation of spatial units. Our starting point is the apparent similarity in the scalar terminology utilised in the two fields, pointing to an area of potential conceptual overlap between physical and human geography. While our aim is not to produce an overarching theory of scale, we seek to advance …
