Discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), salinity, nutrients and temperature during the CCGS John P. Tully and CCGS Vector time series cruises in the Strait of Georgia of the North American Pacific coast in 2003 and between 2010 and 2012 (NCEI Accession 0173514)

Metadata Updated: February 1, 2025

This dataset consists of discrete profile measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), salinity, nutrients and temperature during the CCGS John P. Tully and CCGS Vector time series cruises in the Strait of Georgia (SoG) of the North American Pacific coast in 2003 and between 2010 and 2012. The SoG is a large semi-enclosed estuary that spatially dominates the Salish Sea on the North American Pacific coast. The region is well populated, harbors significant aquaculture, and is vulnerable to climate change. We present the first inorganic carbon data collected in the SoG covering all seasons (2003 and 2010–2012) and put them into the context of local circulation and oxygen cycles. Results show that the SoG has a higher carbon content and lower pH than surrounding waters. Aragonite saturation horizons in the SoG do not become deeper than 20–30 m and shoal to the surface for extended periods. Furthermore, incoming upwelled “acidified” water from the outer coast actually increases local pH. Finally, intense mixing in the physically restricted channels connecting the SoG to the outer coast allows significant oxygen uptake but minimal carbon dioxide (CO2) out gassing, protecting the SoG from hypoxia but not from ocean acidification.
