Preparation of acetate peels of valves from the ocean quahog, Arctica islandica, for age determinations
Techniques are described for preparing acetate peels of sectioned valves of ocean quahogs, Arctica islandica, for age determinations. The respective sequence of preparation begins by sectioning left valves oriented to include a single hinge tooth, bleaching to remove the heavy periostracum, embeddin...
