WebChanging CO2 values affect the PH of the ocean, and this has various effects on the plankton fossils and carbonate chemistry. One effect is that the chemical speciation of boron in their shells will be affected. High CO2 dissolves in the ocean as carbonic acid, acidifying the water and causing there to be more B(OH)3 relative to B(OH)4.
