Hydrochemical data for waters from the Tinto and Odiel rivers and the Ria de Huelva estuary sampled in 2024

This dataset contains hydrochemical data for estuarine water samples from the Ria de Huelva estuary (Spain) (tab 2) and for river waters impacted by acid mine drainage collected in the Odiel and Tinto catchments draining into this estuary (tab 3). In addition, it contains hydrochemical data for river water – seawater mixing experiments using samples from this estuarine system to study the neutralization of acidity in the river waters by alkaline seawater – Neutralization experiments (NEs) (tab 3 and 4).
