Hydrochemical and catchment landcover data from the Tana River basin, northern Fennoscandia

The dataset presents water chemistry measurements and associated catchment landcover characteristics from catchments of the Tana River basin in northern Fennoscandia. Samples were collected during two summer field campaigns representing contrasting hydrological conditions: August 2017 (wetter conditions) and July 2018 (drier conditions). The dataset includes concentrations of dissolved organic carbon (DOC), dissolved metals, and selected major ions, together with sampling coordinates and catchment-scale landcover information derived from CORINE classification. Landcover is provided as raw pixel counts for CORINE classes for each subcatchment. This dataset contains the data used in the following submitted manuscript: Knutson, J. K., Overduin, P. P., de Wit, H. A., Clayer, F., Hessen, D. O., and Westermann, S.: Hydrological Conditions and Landcover as Drivers of Dissolved Organic Carbon Concentrations in the Tana River Basin in Northern Scandinavia, [submitted to JGR: Biogeosciences].
