Carbon Dioxide Removal

An opportunity to study Ocean Alkalinity Enhancement, carbon dioxide removal, and ecosystem impacts through coastal liming

Why we care Terrestrial liming, or the addition of a basic (alkaline) material like calcium carbonate to crops and lawns is a common agricultural soil treatment. When applied on land in the coastal zone, this alkalinity likely influences neighboring bodies of water and may foster carbon dioxide removal and mitigate local ocean acidification. This project

Tidal wetlands as a low pH environment for accelerated and scalable olivine dissolution

Why we care Enhanced weathering is a carbon capture technology that increases ocean alkalinity by adding rocks with ultrabasic minerals, particularly in ecosystems like wetlands and mangroves. This project examines the safety, efficacy, and potential for large-scale implementation of enhanced weathering in tidal wetlands to enhance weathering as a method of carbon dioxide removal and

Assessing the laboratory and field responses of diatoms and coccolithophores to ocean alkalinity enhancement

Why we care Ocean alkalinity enhancement relies on modifying the acid-base properties of seawater to remove carbon dioxide, however the effect of this strategy on primary productivity, cell physiology, and carbon export remain unknown. These impacts are not only potential ecosystem effects, but may influence the efficiency of carbon dioxide removal. This research focuses on

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

Developing a coupled benthic-pelagic biogeochemical model to evaluate the effectiveness of mCDR interventions

Why we care The ocean seafloor, or benthos, serves as the only long-term storage of oceanic carbon on geologic timescales. However, the interaction between ocean water and sediments and its role in carbon storage is a major knowledge gap. Understanding this feedback is important for assessing the duration of carbon storage for ocean carbon dioxide

Assessing Carbon Dioxide Removal and Ecosystem Response for an Ocean Alkalinity Enhancement Field Trial

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

Engaging U.S. Commercial Fishing Community to Develop Recommendations for Fishery-Sensitive mCDR Governance, Collaborative Research and Monitoring, and Outreach to Fishing Communities

Why we care Marine carbon dioxide removal strategies will interact with fishery ecosystems, resources, and activities. It is important to engage with commercial fisheries early to develop an accurate understanding of governance concerns to build trust and fishery-sensitive governance.  What we will doThe project will leverage existing networks of fishermen from the Northeast, Alaska, and

Adaptation approaches fostered by the OAP include:

FORECASTING

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

MANAGEMENT

Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes

TECHNOLOGY DEVELOPMENT

Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally

TAKE ACTION WITH YOUR COMMUNITY

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
