Seawater carbonate chemistry and larva size, elemental composition of Pacific razor clams (Siliqua patula) in Alaska

This study examines the effects of OA on embryonic and larval Pacific razor clams (Siliqua patula), a bivalve that produces a concretion during early shell development. Larvae were spawned and cultured over 28 days under three pCO2 treatments: a static high pCO2 of 867 matm, a variable, diel pCO2 of 357 to 867 matm, and an ambient pCO2 of 357 matm.
