How can Norwegian mountain peatbogs represent useful archives to understand the effect of climate on peatlands carbon budget?

There is extensive literature on temporal carbon accumulation changes in arctic and boreal peatlands in northern peatlands, but little has been achieved in comparing mountain peatlands carbon sinks capacities in wet regions such as Norway. Projections in Norway show a rise in temperature and annual rainfall with more intense seasonal events in western, eastern, and northern parts. In this context, this study hypothesizes that temporal variability of temperature and precipitation during the Holocene led to weaker and stronger evapotranspiration and moisture signals affecting local and regional vegetation in peatland ecosystems, water-table changes, and carbon accumulation capacity. This study aims in disentangling the responses of the carbon budget at different hydrological gradients during the Holocene and compare temporal carbon sink capacity of peatlands in two of the most important plateaus not only in Norway, but in Europe. Methods involve a multiproxy approach to reconstruct carbon accumulation rate, local vegetation changes, %C and % N to investigate the relationship between the proxies and Holocene carbon changes. Results for Carbon accumulation rates, show very specific trends in early, mid and late Holocene and correlation with Temperature and Precipitation reconstructed values at different stages of the Holocene.
