Tracing chemical diversity in dissolved organic matter from freshwaters to marine environments

This dataset provides detailed measurements of the chemical composition and proton-binding properties of dissolved organic matter (DOM) collected along the Ebro River continuum, from its headwaters to the Mediterranean Sea. Samples were collected across different seasons to capture spatial and tempo...
