Calcium carbonate (CaCO3) sediment dissolution under elevated concentrations of carbon dioxide (CO2) and nitrate (NO3−)
International Atomic Energy Agency (IAEA) Publications
Ocean acidification (OA), attributed to the sequestration of atmospheric carbon dioxide (CO2) into the surface ocean, and coastal eutrophication, attributed in part to land-use change and...

Bryozoans as southern sentinels of ocean acidification: a major role for a minor phylum
International Atomic Energy Agency (IAEA) Publications
Rapid anthropogenic production of CO2 has driven the carbonate chemistry of the sea, causing lowered pH in surface waters. Increasingly, scientists are called on to study ocean...

Ocean acidification affects prey detection by a predatory reef fish
International Atomic Energy Agency (IAEA) Publications
Changes in olfactory-mediated behaviour caused by elevated CO2 levels in the ocean could affect recruitment to reef fish populations because larval fish become more vulnerable to...

Shift from coral to macroalgae dominance on a volcanically acidified reef
International Atomic Energy Agency (IAEA) Publications
Rising anthropogenic CO2 in the atmosphere is accompanied by an increase in oceanic CO2 and a concomitant decline in seawater pH (ref. 1). This phenomenon, known as ocean acidification...
