The Potential Effect of Ocean Acidification on the Behavior of the Grass Shrimp Palaemonetes vulgaris
As atmospheric concentrations of carbon dioxide (CO2) rise, the ocean acts as a sink and absorbs this CO2. This absorption mixes CO2 with seawater, forming carbonic acid, which dissociates into bicarbonate ions, carbonate ions, and hydrogen ions. The production of hydrogen ions as a result of the ab...
