    • Water temperature, salinity, total alkalinity, pH, partial pressure of CO2 (pCO2), and calcite saturation measured using water samples collected at the Mukilteo Research Station located in the Puget Sound, WA from 2018-08-26 to 2019-07-11 (NCEI Accession 0300467)

    Metadata Updated: March 1, 2026

    This dataset contains the seawater chemistry monthly means with standard deviations measured using water samples collected at the Mukilteo Research Station located in the Puget Sound, WA from 2018-08-26 to 2019-07-11. Water temperature (°C) is from the average of all 4 Durafet pH sensors deployed in the experimental tanks. Salinity data are from periodic measurements taken of all 6 experimental tanks use a hand-held Orion salinity sensor. The ambient and high-CO2 pH values are spectrophotometric pH averages from all treatment tanks. Alkalinity was calculated from the salinity values using the functional relationship in (Trigg et al., 2019). The pCO2 and calcite saturation state values were calculated using the SeaCarb R package (Gattuso et al., 2021) with the spectrophotometric pH and calculated alkalinity values as carbonate system parameter inputs. No spectrophotometric pH or Orion salinity data were recorded for January because a U.S. Government shutdown prevented collection of these data. However, automated pH and salinity sensors operating in the experimental tanks during January indicate that interpolation by averaged data from December and February, is a reasonable approximation.
