Characterisation and quantification of organic carbon burial using a multiproxy approach in saltmarshes from Aotearoa New Zealand

Files included are supplementary information for the journal publication by the same name submitted for review to Biogeosciences (2025/2026). The data also forms part of a doctoral thesis by Olga Albot submitted to Victoria University of Wellington. Please refer to V2. Tabs include raw data for each respective study site in the following order: 1) Pāuatahanui2) Robert Findlay3) Omaia4) Oktatakata5) Awanui Raw data for each study site include: sample name, sample depths, total organic carbon content (TOC; wt%), total nitrogen (TN; wt%), dry bulk density (DBD; g/cm3), carbon density (CD; g/cm3), delta_13C (‰), delta_15N (‰), Si (ppm), Ca (ppm), S (ppm), Zn (ppm), Zr (ppm), Mn (ppm), Ti (ppm), Nb (ppm), K (ppm), Sr (ppm), Rb (ppm), Fe (ppm), Al (ppm), Pb (ppm), Cu (ppm). Pāuatahanui, Oktatakata and Awanui also contain lipid biomarker indices inclidng: CPI, OPE, Paq, ACL and stanol-sterol. Tabs 6, 7 and 8 include rplum generated age-depth models for Robert Findlay, Okatakata and Awanui, respectively. Tab 9 provides the raw lead isotope (210Pb) data used to model the age-depth outputs in rplum. Tab 10 provides the results of radiocarbon (14C) dating.
