Short summary

The coastal ecosystem of the Gulf of Alaska (GOA) is especially vulnerable to the effects of ocean acidification and climate change. To improve our conceptual understanding of the system, we developed a new regional biogeochemical model setup for the GOA. Model output suggests that bottom water is seasonally high in CO₂ between June and January. Such extensive periods of reoccurring high CO₂ may be harmful to ocean acidification-sensitive organisms.
