ECOA-4 mission samples most northern line ever
The fourth East Coast Ocean Acidification cruise completed the first leg sampling the most northern line ever.

The fourth East Coast Ocean Acidification cruise completed the first leg sampling the most northern line ever.

NOAA launched the fourth East Coast Ocean Acidification (ECOA-4) research cruise to monitor ocean acidification and impacts on marine resources.

The NOAA Ocean Acidification Program presents major highlights of ocean acidification research, monitoring and outreach over fiscal year 2025.

NOAA and partners have launched a new buoy in Fagatele Bay within NOAA’s National Marine Sanctuary of American Samoa to measure the amount of carbon dioxide in the waters around a vibrant tropical coral reef ecosystem.
“This new monitoring effort in a remote area of the Pacific Ocean

Whether you arrive on the Olympic Peninsula by land, sea, or air, you sense its remote, rugged and vast environment immediately. The Olympic Coast is home to productive waters which sustain thriving marine and coastal communities that have long supported the region’s tribal peoples. Ocean waters quickly deepen just offshore,

NOAA Research & Ocean Acidification Program This summer, NOAA and partner scientists will conduct their most collaborative ocean acidification sampling of the Gulf of America (fomerly known as Gulf of Mexico) yet. Set to depart today, July 18th, the Gulf of Mexico Ecosystems and Carbon Cruise (GOMECC-3) will travel through

Oregon State University A three-year survey of the California Current System along the West Coast of the United States found persistent, highly acidified water throughout this ecologically critical nearshore habitat, with ‘hotspots’ of pH measurements as low as any oceanic surface waters in the world.

Intergovernmental Oceanographic Commission for the Western Pacific (WESTPAC) 46 Scientists from the region gathered again in Phuket, Thailand, 29-31 August 2016, stepping up their efforts to develop a long term program monitoring the ecological impacts of ocean acidification on coral reef ecosystems for the region.The three-day WESTPAC event is a
The Surface Ocean CO2 Atlas (SOCAT) The Surface Ocean CO2 Atlas (SOCAT, www.socat.info) is a synthesis activity by the international marine carbon research community (>100 contributors). SOCAT version 4 has 18.5 million quality-controlled, surface ocean fCO2 (fugacity of carbon dioxide) observations with an accuracy of better than 5 μatm from 1957 to 2015
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:
