Abstract

The geochemistry of biogenic carbonates is an established proxy to record changing seawater parameters. However, the effect of ocean acidification on seawater chemistry and organism physiology may impact isotopic signatures and how elements are incorporated into carbonate shells. In this study, we investigated the geochemistry of three reservoirs important for biomineralization--seawater, the extrapallial fluid (EPF), and the shell. Ocean acidification laboratory experiments were conducted at [_...
