Abstract

This data includes near monthly measurements of discharge, water isotopes, water quality, and dissolved organic matter characteristics from the Tapajós River, Brazil between 2016-2023. Dissolved organic matter was characterized via dissolved organic carbon quantification, optical spectroscopy, fluorescence spectroscopy, parallel factor analysis modeling (PARAFAC), and Fourier transform-ion cyclotron resonance mass spectrometry. Pairing geochemical and molecular-level data reveal both seasonal and inter annual patterns of carbon export to the Amazon River system and processing within the river network.
