Supplementary Tables and Source Data for 'Decadal increase in groundwater inorganic carbon concentrations across Sweden'

This resource contains Supplementary Tables and Source Data for the manuscript entitled 'Decadal increase in groundwater inorganic carbon concentrations across Sweden' by Klaus, M., under conditional acceptance in Communications Earth & Environment. The manuscript is based on groundwater chemistry observations from 55 sampling sites distributed across Sweden and sampled quarterly between 1980 and 2020 within the Swedish national groundwater monitoring program run by the Geological Survey of Sweden. The Supplementary Tables contain statistical analyses of linear trends in water chemistry, including among others concentrations of dissolved inorganic carbon, carbon dioxide, alkalinity, pH. The source data contain point observations and linear trends in dissolved inorganic carbon, carbon dioxide, bicarbonate, pH and several acidification proxies. For details, see the variable description and table caption files, as well as the manuscript.
