An integrated investigation of the effects of ocean acidification on adult abalone (Haliotis tuberculata)
International audience Abstract Ocean acidification (OA) and its subsequent changes in seawater carbonate chemistry are threatening the survival of calcifying organisms. Due to their use of calcium carbonate to build their shells, marine molluscs are particularly vulnerable. This study investigated...
