Gulf of St. Lawrence and Estuary Dataset (GOSLED): A 20-Year Compilation of Quality-Controlled Biogeochemical Observations (2003–2023) | Jeu de données sur le golfe du Saint-Laurent et son estuaire (GOSLED) : Compilation sur 20 ans d'observations biogéochimiques soumises à un contrôle de qualité

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.
