Investigating responses of calcium carbonate nucleation rates in artificial seawater to changes in saturation states due to ocean acidification
Senior thesis written for Oceanography 445 [author abstract] Reduced saturation states of carbonate ions caused by ocean acidification make it harder for marine calcifiers such as corals to build their shell or skeleton. Nucleation is vital to corals because it is a necessary precursor to the crysta...

Nucleation is vital to corals because it is a necessary precursor to the crystal growth that builds coral skeletons. This study examines changes in inorganic calcite nucleation rates over different carbonate saturation states as a first step to understanding aragonite nucleation and predicting how coral growth is affected by changes in acidity.

Inorganic calcite nucleation rates are sensitive to carbonate saturation states based on nucleation pathways and classical nucleation theory.
