A study of the shell mineralogy of the marine mussel Mytilus californianus finds a shift in shell mineralogical composition over the past 60 years, with an increase in calcite and a decrease in aragonite, suggesting that ocean acidification, rather than warming or salinity changes, is likely responsible for this shift.
