     Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now

a new study has confirmed that atmospheric CO₂ is also affecting the ocean chemistry and potentially harming

sea life. 

     Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean

for almost two decades.

     "We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change

in the open ocean environment. And one of the key things that we measure is CO₂ levels. And we've been

able to record this increasing quantity of atmospheric CO₂ into the ocean."

     Scientists expected that as atmospheric CO₂ increased, more and more of the carbon dioxide would be

absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact

on shellfish and coral in particular.

     "As carbon dioxide dissolves (溶解) in the water, or seawater in this case, it forms a weak acid (酸),

carbonic acid," Dore explains. "And therefore, as the concentration of CO₂ in the atmosphere goes up and

that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."

     The seawater Dore and his colleagues have analyzed confirms what the theory predicts.

     The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his

colleagues came up with two possible explanations. It could be that surface water picked up CO₂ and then

moved to those depths. Or there could be a biological explanation.

     "It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on

a whole variety of sea life from fish to coral. It's potentially catastrophic."
