Ocean acidification is a complex issue that is being studied and addressed from several viewpoints, in various locations, and for different issues. Within the sanctuary system, sanctuary sites across the country and United States territories are studying how this change in ocean chemistry will and already is affecting their sites. Some sites are being hit
NOAA launched the fourth East Coast Ocean Acidification (ECOA-4) research cruise to monitor ocean acidification and impacts on marine resources.
NOAA launches dual coastwide ocean acidification research cruises (ECOA-4, WCOA 2026) to track ocean chemistry and impacts on marine resources this June.
This review article provides an overview of 68 existing ocean carbonate chemistry data products and data product sets, encompassing a broad range of types, including compilations of cruise datasets, gap-filled observational products, model simulations, and more. It is designed to help researchers identify and access the data products that best support their scientific objectives, thereby
Ocean acidification (OA) is a pressing global issue characterized by fundamental changes in ocean chemistry, including the reduction of pH levels, due to the absorption of increased atmospheric CO2. This phenomenon poses significant threats to marine ecosystems, affecting biodiversity, food security, and coastal economies. Time-series observations remain indispensable for documenting these changes, offering insights into
As climate change continues to increase in severity, the window of time available to achieve climate stabilization decreases. In addition to reducing emissions, climate solutions such as marine carbon dioxide removal (mCDR) are being considered. If mCDR is to scale from research to implementation it will impact various sectors including fisheries and aquaculture. Well-coordinated, co-developed

Understanding seasonal changes in ocean acidification in Alaskan waters and the potential impacts to the multi-billion-dollar fishery sector is a main priority. Through work funded by NOAA’s Ocean Acidification Program, the Pacific Marine Environmental Laboratory developed a model capable of depicting past ocean chemistry conditions for the Bering Sea and is now testing the ability of this model to forecast future conditions. This model is being used to develop an ocean acidification indicator provided to fisheries managers in the annual NOAA Eastern Bering Sea Ecosystem Status Report.
The NOAA Ocean Acidification Program (OAP) works to prepare society to adapt to the consequences of ocean acidification and conserve marine ecosystems as acidification occurs. Learn more about the human connections and adaptation strategies from these efforts.
Adaptation approaches fostered by the OAP include:
Using models and research to understand the sensitivity of organisms and ecosystems to ocean acidification to make predictions about the future, allowing communities and industries to prepare
Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes
Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally
Drive fuel-efficient vehicles or choose public transportation. Choose your bike or walk! Don't sit idle for more than 30 seconds. Keep your tires properly inflated.
Eat local- this helps cut down on production and transport! Reduce your meat and dairy. Compost to avoid food waste ending up in the landfill
Make energy-efficient choices for your appliances and lighting. Heat and cool efficiently! Change your air filters and program your thermostat, seal and insulate your home, and support clean energy sources
Reduce your use of fertilizers, Improve sewage treatment and run off, and Protect and restore coastal habitats
You've taken the first step to learn more about ocean acidification - why not spread this knowledge to your community?
Every community has their unique culture, economy and ecology and what’s at stake from ocean acidification may be different depending on where you live. As a community member, you can take a larger role in educating the public about ocean acidification. Creating awareness is the first step to taking action. As communities gain traction, neighboring regions that share marine resources can build larger coalitions to address ocean acidification. Here are some ideas to get started:
