Abstract

This dataset includes individual absorbance spectra and excitation emission fluorescence spectra from river water sampled near-monthly from the Tapajós River, Brazil between 2016-2023. Both absorbance and fluorescence data were collected on a Horiba Aqualog spectrophotometer. Trends in optical absorbance and fluorescence maxima reveal signatures for DOM sourcing into the river as well as evidence for in-stream processing and molecular stability of exported organic matter.
