Nitrogen and Carbon isotope data from 210Pb dated lake sediment cores in the United Kingdom

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.

本数据集包含英国境内各类湖泊类型与汇水区的湖芯沉积物历史碳、氮同位素测量数据，共计95份样本（n=95）。该数据源自环境变化研究中心（Environmental Change Research Centre, ECRC）的湖芯沉积物档案库，其时间间隔经放射测年（210Pb；137Cs）精确标定，覆盖1850年、1900年、1980年及当前时段。本数据集经整理汇编，用于探究湖泊中碳与氮的历史来源及其累积过程。此外，本数据集可为英国自然环境研究委员会（Natural Environment Research Council, NERC）大营养物计划下属的长期大规模（Long Term Large Scale, LTLS）项目的水文/营养盐模拟工作提供历史数据支持。
