Short summary
We differentiate between sources of dissolved organic matter (DOM) (terrestrial, marine autochthonous production, and artificial island and seawater interaction) in coastal bay waters surrounded by large cities using multiple DOM tracers, including dissolved organic carbon (DOC) and nitrogen (DON), stable carbon isotopes, fluorescent DOM, and the DOC/DON ratio.
