Baynes Sound, located on the northwestern side of the Strait of Georgia, has been a site for shore-based and high-resolution measurement of surface seawater CO2 content since March 2017. Measurements of in situ temperature, salinity, and CO2 partial pressure are made near-continuously from a seawater intake line at the Taylor Shellfish facility Fanny Bay Oysters with an intake 300 m from shore and at a depth of 8 m in Mud Bay, a peripheral bay on the eastern side of Baynes Sound. The effort to collect these data are part of the Hakai Institute’s directive to advance the understanding of carbon cycling in northeast Pacific coastal settings with specific emphasis on sea-air CO2 exchange and ocean acidification. This data contribution consists of measurements collected from March 7, 2017 to November 7, 2017.
