Oregon Coordinating Council on Ocean Acidification and Hypoxia

Oregon was one of the first places in the world to experience the direct impacts of ocean acidification and hypoxia (OAH) with the collapse of the Whiskey Creek Shellfish Hatchery in 2007. These changes in ocean acidity and oxygen are approaching or meeting levels that are problematic for oysters, crab, mussels, urchins, salmon, rockfish, and other species that Oregonians care deeply about. 
To address these issues, the Oregon Coordinating Council on Ocean Acidification and Hypoxia (OAH Council) was convened by Senate Bill 1039 in 2017. The OAH Council produces Oregon's OAH Action plan every six years and Oregon's legislative reports on OAH every two years. For more information on the OAH Council and its work, visit the Council Information page.  
Ocean acidification is a chemical change that occurs when carbon dioxide (CO2) is absorbed by seawater, lowering seawater pH (making it more acidic). 
Hypoxia refers to water conditions where the concentration of oxygen is so low that it is harmful to organisms. Climate change driven changes in wind and weather patterns have led to more frequent and predictable hypoxic events, stressing a wide range of marine animals from crabs to fish. 

On June 22, 2021, the Oregon legislature passed House Bill (HB) 3114, representing a historic investment in Oregon’s efforts to combat ocean acidification and hypoxia. With some direct appropriations to existing work groups at Oregon State University and Oregon Department of Fish and Wildlife, the bulk of the $1.9 million, one-time investment, was distributed through competitive grants led by the Oregon Ocean Science Trust (OOST). This was the first OOST “request for proposals” or RFP process, since the Trust was created by the legislature in 2013. All projects funded by the legislation were identified in the 2019-2025 Oregon OAH Action Plan.

On April 14, 2023, progress from all HB3114 projects were presented at a first annual Oregon OAH Symposium. With over 80 stakeholders, resource managers, journalists, and invested members of the public in attendance, this event was a great step in spreading awareness and interest in ocean change. A recording of the Symposium is available on YouTube.

Ocean acidification and hypoxia (OAH) 

OAH is a change in ocean chemistry that is happening right here right now. And, it is occurring at a faster rate than originally predicted. This phenomena has the potential to have profound impacts on living marine resources. Unfortunately, Oregon has the dubious honor of being the locale that first documented these impacts. In 2007, the Whiskey Creek Shellfish Hatchery had a massive hatchery failure due to acidic oceanic conditions (see the Case Study below).
