Forecast Fish and Marine Mammal Population Responses to Ocean Acidification in the North Pacific Ocean and Bering Sea

Approximately 30-50% of global anthropogenic CO2 emissions are absorbed by the world’s oceans (Feely et al. 2004, Sabine et al. 2004). Increased CO2 uptake by the oceans is expected to reduce surface ocean pH by 0.3 – 0.5 units over the next century, which...

Forecast Fish, Shellfish, and Coral Population Responses to Ocean Acidification in the North Pacific Ocean and Bering Sea

The North Pacific Ocean is a sentinel region for signs of ocean acidification. Approximately 30-50% of global anthropogenic carbon dioxide (CO2) emissions are absorbed by the world’s oceans. Dissolving CO2 increases the hydrogen ion (H+) concentration in the...
