The data provided here are from cruise SKQ2021-08S onboard the R/V Sikuliaq from May 21-June11, 2021 in the Bering and Chukchi Seas. The objective of the study was to evaluate the spatiotemporal dynamics of the carbon dioxide seawater system in the Pacific Arctic during the time of active sea ice retreat. This dataset includes discrete water column data for dissolved inorganic carbon and spectrophotometric pH on the total scale (measured at 25 degrees Celsius) along with nutrients, dissolved organic carbon, and in-situ hydrographic parameters. The outputs from carbonate system calculations (e.g., aragonite saturation state, in-situ pH) are also included. The dataset also includes continuous surface partial pressure of carbon dioxide (pCO2) data in both ppm and uatm measured at 15 minute intervals.
