A dataset of historical sediment Carbon and Nitrogen isotope measurements from lake cores (n=95) spanning the range of lake types and catchments found across the UK. These data have been obtained from the Environmental Change Research Centre (ECRC) lake sediment core archive with well-resolved time intervals (1850, 1900, 1980 and present) determined by radiometric dating (210Pb; 137Cs). This data has been collated to investigate historical sources and accumulation of C and N in lakes. This dataset provides historical data for hydrological / nutrient modelling from the Long Term Large Scale (LTLS) Project in the NERC Macronutrients programme.

This dataset is part of the following
The Environmental Change Research Centre (ECRC), University College London core archive has been used to compile a UK wide, time slice dataset of lake sediment Nitrogen and Carbon and stable isotope measurements. The sediment archive has grown from lake coring projects undertaken by the department and employees of ENSIS Ltd, the environmental consultancy based within the ECRC. Details of core materials in the archive are maintained by the ECRC-UCL "AMPHORA" database from which core location, collection date, lake name and LOI 550% (organic content) values are were derived for this dataset. Measurements of sediment Carbon and Nitrogen and their stable isotope ratios from the selected time/depth intervals have been added to this data.
