Groundwater-surface water interactions as controls on hydrochemical transfer and nitrogen availability in a nitrate-enriched calcareous fen

Two datasets covering May 2021 to May 2022. The hydrochemical dataset contains water quality measurements (nutrients, metals, and organic carbon) taken across multiple sampling sites. The hydrological dataset contains daily groundwater level readings from a network of boreholes and fen dipwells, alongside daily abstraction rates and rainfall. Water levels are expressed in meters above Ordnance Datum (AOD).
