The Biological Impacts Graphics from MACAN show conditions where negative impacts have been observed and potentially lethal conditions for Mid-Atlantic species. These graphics explore how species are impacted by the natural differences in pH and aragonite saturation values across different coastal and marine habitats.

The Northeast Coastal Acidification Network (NECAN) report presents monitoring needs and opportunities for consideration by coastal managers, decision makers, researchers, and monitoring groups. It offers options to apply new capacity or funding to the expansion of OCA monitoring in the NECAN region. The report identifies highly-rated, specific actions that will improve both:

This report is the output of the Workshop on Marine Carbon Dioxide Removal (WKMCDR) held on October 2024. The workshop focused on four types of mCDR: ocean alkalinity enhancement, ocean nutrient fertilization, direct ocean capture, and macroalgae cultivation andsinking (National Academies of Science, Engineering, and Medicine, NASEM, 2021). The topics that were discussed at this

This document is intended to serve as a reference for exploration of carbon removal research at NOAA. It provides strategic direction to relevant labs and programs in multiple line offices within NOAA. The goal has been to assemble as much information as possible in order tofacilitate conversations about Carbon Dioxide Removal (CDR) at a high

This landscape analysis seeks to identify the “who” and “where” of United States in situ global ocean carbon observing, analyzing where gaps in these efforts remain. Aircraft and satellites collecting atmospheric carbon measurements (and other parameters necessary for carbon flux calculations) were not included in this analysis focused on in situ observations. This study was

The intent of this Science Plan is to outline OAR’s goals related to ocean carbon observing, set priorities, and enable coordination with intra-agency, interagency, and international partners. The three goals of this 10-year Science Plan support OAR’s long term vision to advance carbon cycle science; improve ocean, coastal, and Great Lakes models and product development;

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:
