attribute	NC_GLOBAL	summary	String	The Pacific Ecosystem Autonomous Research Laboratory (PEARL) at the Bamfield Marine Sciences Centre has been a site for shore-based and high-resolution measurement of surface seawater CO2 content since August 2025. Measurements of in situ temperature, salinity, and CO2 partial pressure are made near-continuously on seawater drawn from a sample line with an intake 15 m from shore and a depth of 1 m in Barkley Sound on the west coast of Vancouver Island. The effort to collect these data is part of the Hakai Institute’s mission to advance the understanding of carbon cycling in northeast Pacific coastal settings with specific emphasis on ocean acidification.
