A one-year study of two ponds and a river in Rhode Island was implemented to determine whether Elliptio complanata secretes aragonite in oxygen isotopic equilibrium with the water in which they grow. In fact, disequilibrium is manifested as an offset of approximately -2‰ in the summer and -2.5‰ in the winter. Incorporation of metabolic CO2 may contribute in large part to this offset. -from Authors
