Short summary
Wetlands commonly feature high levels of natural dissolved organic matter (DOM), a critical component in their biogeochemical functions. Here we describe the first detailed, comparative, molecular characterization of DOM in three sub-tropical, pulsed, wetlands, using optical properties, high field nuclear magnetic resonance and ultrahigh resolution mass spectrometry, and compare compositional features to variations in organic matter sources and flooding characteristics.
