Mean and standard error values of isotopes carbon isotope (δ13C), nitrogen isotope (δ15N), bulk organic carbon (C) and total nitogen (N) for terrestrial trees, mangroves trees, seagrass plants and oceanic sources.

The values for each source (highlighted) are the means of the different contributions (species for terresrtial, mangrove and seagrasses & SPM/plankton for oceanic). These values are defined as the end members (organic matter sources), which are used in the mixing model to determine the different mixture of fractions for organic matter. The organic matter was collected in the core, sediment trap and suspended sediment matter samples. n, is the number of samples and SE is standard error.Mean and standard error values of isotopes carbon isotope (δ13C), nitrogen isotope (δ15N), bulk organic carbon (C) and total nitogen (N) for terrestrial trees, mangroves trees, seagrass plants and oceanic sources.
