This dataset comprises water chemistry data (dissolved organic carbon (DOC), total dissolved nitrogen (TdN), particulate organic carbon (POC), total phosphorus (TP), soluble reactive phosphorus (SRP), absorbance at 254nm (Abs 254), specific ultraviolet absorbance (SUVA), and dissolved CH4, CO2, N2O) collected bi-weekly from peatland streams near Penicuik, Scotland, in 2022 and 2023. Data were obtained via collection of water samples in situ, and concentrations were derived via subsequent sample processing and analysis. The objective of this dataset is to provide background data to characterise differences in the baseline period before restoration at the sampling site occurs.

The dataset contains aquatic carbon and dissolved greenhouse gas data collected from 6 headwater stream sampling sites within the UK’s largest tract of blanket bog, the Flow Country of N. Scotland. The streams drain from catchments under different peatland management regimes: natural non-drained peatland, drained peatland, and restored peatland (achieved via ditch blocking). Sites were sampled on an approximately fortnightly basis between September 2008 and August 2010. Data were obtained via collection of water and gas samples in situ, and concentrations were derived via subsequent sample processing and analysis.
