Data from: Quantifying Susceptibility of Marine Invertebrate Biocomposites to Dissolution in Reduced pH
Ocean acidification threatens many ecologically and economically important marine calcifiers. The increase in shell dissolution under the resulting reduced pH is an important and increasingly recognised threat. The biocomposites that make up calcified hardparts have a range of taxon-specific composi...

Ocean acidification threatens many ecologically and economically important marine calcifiers. The increase in shell dissolution under the resulting reduced pH is an important and increasingly recognised threat. The biocomposites that make up calcified hardparts have a range of taxon-specific compositions and microstructures, and it is evident that these may influence susceptibilities to dissolution. Here, we show how dissolution (thickness loss) under both ambient and predicted end-century pH (≈7.6) varies between seven different bivalve mollusc and one crustacean biocomposite and investigate how this relates to details of their microstructure and composition. Over 100 days the dissolution of all microstructures was greater under the lower pH in the end-century conditions. Dissolution of lobster cuticle was greater than for any bivalve microstructure, despite its calcite mineralogy, showing the importance of other microstructural characteristics besides carbonate polymorph. Organic content had the strongest positive correlation with dissolution when all microstructures were considered, and together with Mg/Ca ratio, explained 80-90% of the variance in dissolution.
