Inorganic carbon measurements of saltmarsh soils from wide diameter gouge cores in UK saltmarshes collected between 2018 and 2021

The dataset comprises physical and biogeochemical measurements of saltmarsh soils from across 42 UK saltmarshes. The data provides a quantitative measure of soil dry bulk density and inorganic concentration across soil substrate and marsh types. Between 2018 and 2021, 58 wide diameter gouge cores (60 mm in diameter) were collected to facilitate the calculation of inorganic carbon burial rates in saltmarsh soils. Sites were chosen to represent contrasting habitat types in the UK, in particular sediment types, vegetation and sea level history.
