Study Links Raised Carbon Dioxide Levels to Oyster Die-Offs: A study published in the journal Limnology and Ocea...

Oyster hatcheries along the Washington and Oregon coastlines began experiencing calamitous die-offs beginning in 2006. Scientists suspected they were due to increased carbon dioxide levels in the air that were causing ocean acidification. That theory has now proved out, according to a study just published by the journal Limnology and Oceanography. Researchers began studying the oysters at Whiskey Creek Hatchery in Oregon in 2009 after the hatchery reported that production there had declined by as much as 80 percent in recent years. The scientists paid close attention to the seawater that had bathed the oysters. When oceans, which absorb a significant portion of the rising carbon dioxide in the air, become saturated with that carbon dioxide, a chemical process takes place called acidification . Laboratory studies have already shown that this process reduces the availability...
