SalishCruiseMultistressor_v2025: An updated multi-stressor data product for marine heatwave, hypoxia, and ocean acidification research, including calculated inorganic carbon parameters from the southern Salish Sea and northern California Current System from 2008-02-04 to 2024-10-22 (NCEI Accession 0307626)

This NCEI Accession contains a data product including calculated CO2 system parameters based on the updated Salish cruise data product, now covering 2008–2024 (https://www.ncei.noaa.gov/access/ocean-carbon-acidification-data-system/oceans/SalishCruises_DataProduct.html). We used R seacarb function carb to calculate the most commonly used derived carbonate system parameters, including pH, partial pressures and fugacities of carbon dioxide at in situ temperatures and pressures (pCO2insitu, and fCO2insitu, respectively), and aragonite and calcite saturation states (OmegaAragonite and OmegaCalcite, respectively) (Gattuso et al., 2023). Input parameters from the SalishCruiseMultistressors_v2025 data product (Alin et al. 2025a) comprised dissolved inorganic carbon (DIC_UMOL_KG), total alkalinity (TA_UMOL_KG), phosphate (PHOSPHATE_UMOL_KG), and silicate (SILICATE_UMOL_KG) content values from bottle samples analyzed in the laboratory, along with CTD measurements of temperature (CTDTMP_DEG_C_ITS90), salinity (CTDSAL_PSS78), and pressure (CTDPRS_DBAR). Within seacarb, we used the TEOS-10 thermodynamic seawater equations (IOC, SCOR, and IAPSO, 2010). We adopted the total scale for pH (pHT), the Uppstrom (1974) formulation for deriving total boron concentration from salinity, the seacarb default option for Kf (Perez and Fraga, 1987 for temperatures above 9 °C; Dickson and Goyet, 1994 for those below), and the Dickson (Dickson, 1990) option for Ks (following results of Orr et al., 2015). All input content data were first divided by 10^6 to convert from µmol kg^–1 to mol kg^–1, and pressure (dbar) was divided by 10 to convert to bar, to conform with the default units of seacarb. For equilibrium constants (K1 and K2), we provide calculated values using both the Lueker et al. (2000) and the Waters et al. (2014) dissociation constants. The Lueker constants (for salinity ranges of 19–43 and temperature ranges of 2–35°C) facilitate comparison with publications arising from West Coast Ocean Acidification (WCOA) cruise data sets (https://www.ncei.noaa.gov/access/ocean-carbon-acidification-data-system/oceans/Coastal/WCOA.html), whereas the Waters constants (for salinity ranges of 1–50 and temperature ranges of 0–50°C) allow users working with more brackish salinities to compare their results directly to those in the Salish cruise data product. All references above are included in the seacarb documentation. Alin et al. (2024a,b) describe the magnitude of differences in calculated values for the Salish cruise data product using the two different sets of dissociation constants during 2008–2018, with a preliminary description of 2019–2024 results in Alin et al. (2025b). The data product is available on the Index page accessed by clicking the Database Files link above: The file “SalishCruiseMultistressors_v2025_data_07252025.csv” contains 6527 complete records of DIC, TA, T, S, O2, and nutrient measurements with climate quality quality flags and includes calculated values for the carbonate system parameters described above. For 2019–2024, 26 new quality controlled cruise data sets were added, bringing the total number of cruises in this data product to 61. This effort was conducted in support of the estuarine and coastal monitoring and research objectives of the Washington Ocean Acidification Center (WOAC), the Northwest Association of Networked Ocean Observing Systems, the U.S. National Oceanic and Atmospheric Administration's Pacific Marine Environmental Laboratory, and the U.S. National Oceanic and Atmospheric Administration's Ocean Acidification Program and conforms to climate-quality monitoring guidelines of the Global Ocean Acidification Observing Network (goa-on.org).
