The dataset shows the results of water chemistry and organic matter composition analysis, from water samples collected from surface waters in the UK and Faroe Islands. The water samples were collected from 2018-2020. ... : This experiment was devised in 2018 and the water samples were collected during 2018 – 2020. The water samples were analysed for various water chemistry parameters within 3 months of collection. Samples were stored in the fridge at 4 degrees. Organic matter was extracted by filtration and rotary evaporation within 3 months of collection and analysed for elemental composition within 3 months of extraction. Lab analysis QA steps: 10% of all samples are analysed in a replicate. All equipment is calibrated at the beginning of a run and with multiple checks throughout. Data analysis QA steps: all replicate data are compared, and if within 95% of each other, an average value is used. If the replicates were different, the samples were re-analysed. Once CHNO content had been calculated, restrictions were placed on derived metrics based on physical properties (e.g. bonding). ...
