  1. Excellent project, and a great way to contribute to efforts to make Boston Harbor a healthier ecosystem! In recent years, ocean acidification due to increased atmospheric concentrations of carbon dioxide, and runoff from fertilizers and wastewater leading to subsequent algal blooms and carbon dioxide production, has placed severe stresses on marine life, particularly that life which depends on the availability of carbonate ions. As Sarah Newkirk of the Nature Conservancy explains (, rising levels of carbon dioxide deplete the availability of carbonate ions, making the construction of calcium carbonate - based shells very difficult for species such as oysters.

    What is the process by which calcium carbonate is a 'known buffer that can help offset ocean acidification'?

    Has the Massachusetts Oyster Project documented any challenges to oyster vitality and growth due to ocean acidification?
