Is Friday Harbor OVER saturated with CO2 because of a current that brings in high CO2 water? If so, Puget Sound would be outgassing CO2.
Naturally acidic waters of Puget Sound surround UW’s Friday Harbor Labs

Researchers found typical values of dissolved carbon dioxide, or CO2, in Puget Sound are more than 650 parts per million, higher than even the 400 parts per millionthreshold that Earth’s atmosphere crossed last year for the first time in modern humans’ existence. In other words, Puget Sound’s water is already higher in the gas than our CO2-choked atmosphere.

Murray, a chemical oceanographer, did calculations to trace the origin of water properties measured at the facility. He found that most water in the Sound is from the California Undercurrent, a subsurface current that originates below a productive fishing area off the coast of Mexico and brings water that is high in nutrients and CO2, but low in oxygen and pH, north along the coast. When winds blow from the north off Washington’s coast, the water near the surface gets blown offshore, and this deeper water gushes up and into Puget Sound.
