Project: Dalhousie University Name: William Nesbitt Institution: Dalhousie University InfoURL: https://orcid.org/0000-0002-5217-3267 Source URL: (local files) Unknown tabular digital data Halifax, NS, CA ERDDAP, version 2.28.1, at Canadian Integrated Ocean Observing System https://erddap.cioos.ca/erddap/tabledap/dalhousieBiogeochemistryStLawrence.html https://erddap.cioos.ca/erddap/tabledap/dalhousieBiogeochemistryStLawrence.graph https://erddap.cioos.ca/erddap/tabledap/dalhousieBiogeochemistryStLawrence.subset Dalhousie University This dataset includes 20 years (2003–2023) of biogeochemical observations collected during 21 dedicated research cruises in the Estuary and Gulf of St. Lawrence as well as its main tributary, the Saguenay Fjord. The dataset contains CTD sensor measurements of pressure, temperature, practical salinity, and dissolved oxygen, as well as discrete oxygen measurements determined by Winkler titration. Additionally, the dataset includes discrete carbonate-system parameters such as dissolved inorganic carbon, total alkalinity, pH (total proton scale), and the fugacity of CO₂, along with macronutrient concentrations (nitrate, nitrite, ammonium, soluble reactive phosphate, and silicate). Organic parameters such as dissolved organic carbon and total nitrogen are included, as are the concentrations of selected biogeochemical gases (e.g., nitrous oxide) and the stable carbon isotopic composition of the DIC and DOC, as well as the δ¹⁸O and δD of H₂O. Measured transient tracers include CFC-12 and SF₆ and a deliberate tracer, CF₃SF₅. Data were compiled from both historical measurements (2003–2020) and recent sampling efforts from the MEOPAR–RQM TReX project (2021–2023) and RQM - Odyssée Saint Laurent program (2018-2023). All data were processed following primary quality control procedures adapted from GLODAP and CODAP-NA standards. Secondary crossover analysis was not possible due to a lack of deep-water sampling. This dataset is a rare, quality-controlled biogeochemical time series for the Gulf and St. Lawrence Estuary and provides a baseline for future research on deoxygenation, acidification, and nutrient cycling in Eastern Canada.
