The ocean is both a source of oxygen and a sink for carbon dioxide (CO2). It absorbs about one fourth of all CO2 emissions. While this leaves less CO2 in the atmosphere and mitigates climate change, it makes the ocean more acidic. Ocean acidification has emerged as a global issue because of its effect on marine organisms, ecosystems and livelihoods…

The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean makes the water more acidic and leads to a suite of chemical changes collectively known as ocean…
