Blue carbon stock in Scottish saltmarsh soils

In this study, we provide an estimate of the quantity of organic carbon (OC) held within the surficial soils (top 10 cm and 15 cm) of Scotland’s extensive saltmarsh habitats. This work builds upon the Scottish Saltmarsh Survey (Haynes, 2016) by integrating the mapped extent of saltmarsh vegetation types with field-derived measurements of soil dry bulk density and OC obtained from a diverse range of saltmarsh soils across Scotland (Ruranska et al., 2020). This approach has enabled a new surficial OC stock estimation to be made for the soils within Scotland’s saltmarshes. Publisher PDF
