Panel: Ocean acidification threatens lucrative shellfish sector Colin A. Young BOSTON — As a result of climate change and direct human factors, the waters of the Atlantic Ocean off Massachusetts are becoming more acidic, making them a less friendly habitat for the shellfish that drive a key industry here. With no action, many of the scallops, clams, mollusks and lobsters at the bottom of the ocean in the Gulf of Maine will begin to dissolve by 2060 and new ones will struggle to form, imperiling an industry that supports thousands of people in the Bay State, a special commission said in a report Tuesday.
