FSU researcher: Ocean Acidification Means Major Changes for California Mussels

Accelerating ocean acidification could be transforming the fundamental structure of California mussel shells, according to a new report from a Florida State University-led team of scientists.

For thousands of years, California mussel shells have shared a relatively uniform mineralogical makeup — long, cylindrical calcite crystals ordered in neat vertical rows with crisp, geometric regularity. But in a recent study published in the journal Global Change Biology, researchers suggest that escalating rates of ocean acidification are shaking up that shell mineralogy on its most basic structural levels.
