River channel connectivity shifts metabolite composition and dissolved organic matter chemistry

The underlying mechanisms structuring dissolved organic matter (DOM) composition and reactivity in rivers remain poorly quantified. Here, the authors pair mass spectrometry and fluorescence spectroscopy to show that hydrology and river geomorphology both shape molecular patterns in DOM composition.
