This data package includes two datasets used to assess spatial and temporal patterns in particulate organic matter (POM) chemical composition in surface (0-10 m) waters at 11 oceanographic stations along British Columbia’s Central Coast, associated with St. Pierre et al. (2022, submitted).
The datasets within the data package include:
‘Oceanographic station mixture dataset.csv’: Particulate organic carbon (POC) and particulate nitrogen (PN) concentrations and stable isotope signatures (δ13C, δ15N) and ratios of carbon-to-nitrogen (C:N) in surface waters (0-10 m) across 11 oceanographic stations, sampled during routine monthly surveys conducted between January 21st 2015 and September 11th 2018. Also includes water temperature, salinity, chlorophyll a concentrations, and POC-to-chlorophyll a ratios.
‘End-member raw data.csv’: Particulate organic carbon (POC) and particulate nitrogen (PN) concentrations and stable isotope signatures (δ13C, δ15N) and ratios of carbon-to-nitrogen (C:N) in marine phytoplankton, terrestrial, and marine intertidal macrophyte POM sources. Note that means ± standard deviations for each source were used in the Bayesian mixing model presented in St. Pierre et al. (in review). Marine intertidal macrophyte data are a subset from Froese et al. (2019).

St. Pierre, K.A., Hunt, B.P.V., Giesbrecht, I., Tank, S.E., Lertzman, K.P., Del Bel Belluz, J., Hessing-Lewis, M.L., Olson, A., Froese, T. Marine particulate organic matter chemistry reflects seasonally and spatially variable contributions from terrestrial, intertidal and marine pelagic sources in the Northeast Pacific coastal temperate rainforest.
