This work builds and tests a pilot-scale system for carbon dioxide removal from a gas stream and investigates how the chemicals produced can be used to enable marine carbon dioxide removal.
This project aims to address potential impacts of ocean alkalinity enhancement on phytoplankton by conducting laboratory and field experiments.
Why we care Foraminifera, or forams, are single-celled organisms that produce calcium carbonate shells and play a crucial role in the ocean’s carbon cycle. Ocean alkalinity enhancement aims to increase the ocean’s ability to absorb carbon dioxide by enhancing its buffering capacity. However, the impact of the addition of alkalinity on foraminifera is not well
This project will identify how corals and crustose coralline algae respond to immediate alkalinity additions and to determine the effects of chronic and acute exposure to ocean alkalinity enhancement.
This project will evaluate the feasibility, cost, and potential for carbon dioxide removal by alkalinity addition via existing wastewater treatment discharges.
This project will develop a modeling framework capable of resolving a range of marine carbon dioxide removal concerns related to durability, additionality, verifiability, and other aspects of sediment processes in ocean models.
Why we care Tracking how ocean alkalinity enhancement reduces acidity, resulting in carbon dioxide removal from the atmosphere is important for knowing how, where and when to deploy this approach as well as its potential impacts to marine life. Capitalizing on an ocean alkalinization field trial in the Gulf of Maine already underway, this project
This project will conduct an experiment that adds alkalinity to ocean water to test its effect on removing carbon dioxide with a local wastewater treatment plant in San Francisco Bay.
This project may inform carbon markets and carbon prices/discounts for ocean carbon dioxide removal projects.

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:
