An interesting and useful presentation from Shallin Busch is available on tvw.org (click here). She described impacts on biology (species) from lowering pH levels. Of interest were studies indicating different oysters in their larval stage respond differently. The native Olympia oyster and Suminoe oyster survived far better than the triploid Pacific oysters, the primary "crop" of the shellfish industry. Whether growth in the latter stages was impacted is unknown.

Co-chair Bill Ruckleshaus asked one of the more important questions on addressing Ocean Acidification: Will the upwelling of deep sea waters overwhelm any efforts put forth to address land based causes of increasing acidification in Puget Sound? The deep sea upwelling is currently estimated to be 66% of the cause and will continue to increase over the coming decades as it worsens making the question of just where to focus efforts important. CO2 emissions were estimated to be 8-17% and decomposition 17-26%.
