PROSPECTOR_MarineCarbonateSystem_2019/20/21_FramStrait and Svalbard Fjords
The full set of marine carbonate parameters was collected in the surface waters of the eastern part of the Fram Strait (between 74°N - 81°N, and 0° - 20°E) and Svalbard fjords (Krossfjorden, Kongsfjorden, Isfjorden, and Horsund) during June/July 2019, 2020 and 2021. Water was collected at 2.5m depth using an underway pCO2 system installed on board the RV Oceania. The carbonate systems measurements consist of temperature, salinity, pH, pCO2, Total Alkalinity (TA), and Dissolved Inorganic Carbon (DIC); moreover, the partial pressure of Oxygen was measured (pO2). The temperature was measured at the inlet of the underway system using a SBE38, and, in the laboratories, temperature, and salinity were again measured using a SBE21 SeaCATthermoslinograph, both of them from Sea-Bird Scientific, Bellevue, Washington. Temperature and salinity data were collected every second. The water stream in the laboratory had three main outlets: the first one was connected to a bubble-type equilibrator equipped with an additional spray-type water diffuser, the second one to an automatic spectrophotometric system (CONTROS, 4H-JENA engineering GmbH), and the third one was designated to collect water samples. The pCO2 was measured using a cavity ring-down spectroscope (CRDS) G2101-i (Picarro), while pO2 was obtained using a Fibox 4 equipped with a dipping optode (PreSens GmbH, Germany). Both instruments were connected directly to the headspace of the equilibrator, collecting data every second. The pH was obtained from the spectrophotometric system with a resolution of 30 min. DIC and TA samples were collected in borosilicate bottles, preserved with HgCl2, and measured in different Oceanographical institutions (for more information on methods, see AguadoGonzalo et al., 2024, in prep.). pCO2 (µatm) data was average every minute with a precision/accuracy of 1.3 µatm, pO2 (% atmospheric saturation) was also average every minute with a precision of ±0.3% of the saturation values, pH (in total scale units) yielded a precision of 0.002 pH units and an accuracy of 0.003 pH units, TA and DIC (both in µmol Kg-1)had a combined precision/accuracy better than ± 3 µmol Kg-1 and ± 4 µmol Kg-1, respectively.

pCO2 data: The quality of the The quality of the cavity ring-down spectroscope measurements was regularly monitored measuring three gases with different CO2 concentrations, pure nitrogen (Linde 5.0), 205 and 507 ppm, providing a precision/accuracy of ±1.3µatm. Temperature changes between the water inlet and the equilibrator were corrected using the variations in pCO2 as a function of temperature proposed by Takahashi et al., (1993).

pH Quality: The accuracy/precision was obtained after repeated measurements of the certified TRIS buffer (TRIS-CRM-T37) provided by A.G. Dickson (Scripps Institution of Oceanography, USA) at 25°C.

DIC samples from 2019 were measured on a Shimadzu TOC-L analyzer at the Institute of Oceanology of the Polish Academy of Sciences (IOPAN) in Poland. In 2020, they were measured at the Helmholtz-Zentrum Hereon (Germany) using a VINDTA 3C (Versatile INstrument for the Determination of Total dissolved inorganic carbon and Alkalinity) based on coulometric titration (Johnson et al., 1993). In 2021 measurements were performed on an automated DIC analyzer (Apollo SciTech) at the IOPAN. As for TA, the measurements in 2019 and 2021 were made on an automated, open-cell potentiometric titration system developed by Andrew Dickson (Scripps Institution of Oceanography/UCSD, USA) (Dickson et al., 2007), while in 2020 using VINDTA 3C based on close-cell potentiometric titration. For all DIC and TA measurements, the accuracy was ensured by using certified reference materials (CRMs, batches no. #190 and #195) from A.G. Dickson (Scripps Institution of Oceanography, USA). These were also used for quantification of the precision for each of the used instruments, which was not worse than ± 3 µmol Kg-1 for DIC and ± 4 µmol Kg-1 for TA.
