Rising acid levels in oceans imperil region's shellfish
Description: Bill Mook noticed newly born oysters of his coastal hatchery often failed to thrive after heavy rainfalls. The storms left the brackish seawater he was pumping into his tanks from the nearby Damariscotta River estuary too acidic for the pinhead-sized mollusks. To stay in business, he had to change the pH balance of the water. And as heavy storms have become more frequent in recent years, he has had to adjust that balance more often to keep the oysters alive. His experience reflects drastic changes in the chemistry of coastal waters, the result of increasing acidification, which have been setting off alarms among fishermen, climate scientists, and policy makers from Cape Cod to Casco Bay.
