  • [This dataset is embargoed until March 31, 2022]. This dataset contains particulate and dissolved organic carbon concentrations, nutrients (ammonia, nitrates, phosphate), alkalinity, pH, particulate organic nitrogen, delta-C-13 and delta-15-N isotopes, fluorescence and absorbance from river water samples. Data come from 41 rivers from around Great Britain, sampled on a monthly basis during 2017. LOCATE (Land Ocean CArbon TransfEr) is a multi-disciplinary project that undertakes coordinated sampling of the major rivers in Great Britain to establish how much carbon from soils is getting into rivers and estuaries and to determine what is happening to it. LOCATE is a multidisciplinary NERC project involving the National Oceanography Centre, the British Geological Survey, the Centre for Ecology and Hydrology and the Plymouth Marine Laboratory, with assistance from the University of Lancaster, University of Durham, University of Hull, the University of the Highlands and Islands and the Environment Agency.

  • Data comprise elemental concentrations of Ca, Cs, K, Mg, Sr, NH4-N and NPOC (Non-Purgeable Organic Carbon) measured by ICPMS (Inductively Coupled Plasma Mass Spectrometry), ICPOES (Inductively Coupled Plasma Optical Emission Spectroscopy) or high temperature combustion catalytic oxidation. Samples include a range of freeze-dried crops (grass, radish, potato, strawberry, lettuce, courgette, chard) relevant to the human food chain, soil, soil pore waters and irrigation water. All samples were obtained following two plant growth studies conducted at CEH Lancaster during spring/summer 2018 and 2019 and a study conducted at the University of Extremadura (Cáceres) in the summer of 2018. The study was conducted as part of the CONFIDENCE project which is part of the CONCERT EJP, which receives funding from the European Union’s Horizon 2020 Research and Innovation Programme under grant agreement No 662287.
