"The waters in Puget Sound's main basin are acidifying as fast as those along the Washington Coast, where wild oysters have not reproduced since 2005.

And in parts of Hood Canal, home to much of the region's shellfish industry, water-chemistry problems are significantly worse than the rest of Puget Sound.

Scientists from the University of Washington and the National Oceanic and Atmospheric Administration (NOAA) warned Monday that the changing pH of the seas is hitting Puget Sound harder and faster than many other marine waters."
