Stable isotope signatures of bivalve shells serve as important proxies of past environmental conditions. However, such data can be biased as a consequence of physical and chemical pretreatment and contamination during sampling. To systematically assess these issues, homogenized aragonitic shell powder, as well as Carrara marble powder (calcite) were exposed to ultrasound, a set of different staining solutions and cleaning agents that are typically employed in bivalve sclerochronology....
