Determining the Influence of Ocean Alkalinity Enhancement on Foraminifera Calcification, Distribution, and Calcium carbonate Production

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

Quantifying the Efficacy of Wastewater Alkalinity Enhancement on mCDR and Acidification Mitigation in a Large Estuary

Why we care Manipulating wastewater treatment plant procedures and discharge to enhance carbon removal is practical because of the current readiness of infrastructure to deliver alkalinity to the coastal ocean. Many wastewater facilities already treat wastewater with alkalinity, permits to allow alkalinity discharge already exist, and there are several known technologies that can increase alkalinity

Carbon Dioxide Removal

Data requirements for quantifying natural variability and the background ocean carbon sink in mCDR models

Why we care Ocean uptake of carbon has great natural variability that accompanies rising atmospheric carbon dioxide. A major challenge for marine carbon dioxide removal will be to quantify its additional carbon removal from the atmosphere. Ocean models can quantify carbon uptake attributed to marine carbon dioxide removal will likely be the basis for carbon

Ocean acidification in the Gulf of Mexico: Drivers, impacts, and unknowns

We synthesize the current peer-reviewed literature on Gulf of Mexico (GOM) acidification across the ocean-estuarine continuum and identify critical knowledge, research, and monitoring gaps that limit our current understanding of environmental, ecological, and socioeconomic impacts from acidification.• The GOM remains a relatively understudied region with respect to ocean acidification (OA), particularly with respect to regionally important organism and ecosystem responses.• Within the GOM,

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


On the Road

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.

With your Food Choices

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

With your Food Choices

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

By Reducing Coastal Acidification

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:

  1. Work with informal educators, such as aquarium outreach programs and local non-profits, to teach the public about ocean acidification. Visit our Education & Outreach page to find the newest tools!
  2. Participate in habitat restoration efforts to restore habitats that help mitigate the effects of coastal acidification
  3. Facilitate conversations with local businesses that might be affected by ocean acidification, building a plan for the future.
  4. Partner with local community efforts to mitigate the driver behind ocean acidification  – excess CO2 – such as community supported agriculture, bike & car shares and other public transportation options.
  5. Contact your regional Coastal Acidification Network (CAN) to learn how OA is affecting your region and more ideas about how you can get involved in your community
