Field evaluation of a low‐powered, profiling p CO 2 system in coastal Washington
Abstract Summertime upwelling of deep, corrosive waters on the continental shelf of the northern California Current System can exacerbate ocean acidification conditions, providing unsuitable environments for development of calcifying organisms and finfish that are important to the local economy.
