In this study we assess the total storage, landscape distribution, and vertical partitioning of soil organic carbon (SOC) stocks on Brøgger Peninsula, Svalbard. This type high Arctic area is underrepresented in SOC databases for northern permafrost region. Physico-chemical, elemental, radiocarbon (14C) dating analyses were carried out thirty-two profiles. Results upscaled using both a land cover classification (LCC) landform (LFC). Both LCC LFC approaches provide weighted mean 0–100 cm...
Accurate quantity and distribution estimates of permafrost soil organic carbon (SOC) stocks are needed to project potential feedbacks climate, following warming. Still, upscaling from local field observations regional circumarctic assessments remains a challenge. Here we explore elevation-based techniques for High-Arctic SOC stocks. We combine two detailed, high-resolution inventories on Spitsbergen (Svalbard) with validation data. find clear relationship between elevation content, use this...
ABSTRACT Proglacial environments are ideal for studying the development of soils through changes rocks exposed by glacier retreat to weathering and microbial processes. Carbon (C) nitrogen (N) contents as well soil pH elemental compositions thought be dominant factors structuring bacterial, archaeal fungal communities in early stages ecosystem formation. However, functional linkages between C N contents, composition community structures remain poorly understood. Here, we describe a...
