Marine bivalve shell geochemistry and ultrastructure from modern low pH environments: environmental effect versus experimental bias
<jats:p>Abstract. Bivalve shells can provide excellent archives of past environmental change but have not been used to interpret ocean acidification events. We investigated carbon, oxygen and trace element records from different shell layers in the mussels Mytilus galloprovincialis combined wi...

<jats:p>Abstract. Bivalve shells can provide excellent archives of past environmental change but have not been used to interpret ocean acidification events.
