Terrestrial versus marine sources of organic matter and their converging pathway along the terrestrial plant-soil-riverine-estuarine-marine continuum of the Great Barrier Reef (GBR). Total organic carbon to total nitrogen ratio (TOC:TN) and stable isotope carbon (δ13C) values are presented for plant litter, soil, SPM in riverine and inner estuarine mixing zone (IEMZ); SPM collected from outer estuarine mixing zone (OEMZ); sediment collected by marine traps influenced by flood plume (ITS) and sediment collected by marine traps not influenced by flood plume (NTS). Identifier of OM produced by marine algae is from previous studies20–22. Ellipses highlight the distribution of samples in each category.
