Ocean acidification interactions in the Gulf of Mexico

Xinping Hu – Texas A&M University

Ocean Acidification on a Crossroad: Enhanced Respiration, Upwelling, Increasing Atmospheric CO2, and their interactions in the northwestern Gulf of Mexico
Why we care
In the coastal ocean, local drivers such as nutrient input and physical oceanographic changes impact the magnitude of short-term variations and long-term trends in ocean acidification. The Gulf of Mexico’s coral reefs and banks are ecologically sensitive to changing ocean chemistry. Decadal acidification has been observed in the Northwestern Gulf of Mexico, linked more strongly to biological production of carbon dioxide than uptake of human-emitted carbon dioxide. Whether the observed acidification in this region represents a short-term phenomenon or a long-term trend is unknown. This project maintains critical ocean acidification monitoring in a region with impacted habitats and species. 

What we are doing 
This project will test the hypothesis that enhanced atmospheric carbon dioxide, nutrient input, and upwelling will cause the continental shelf-slope region in the Northwestern Gulf of Mexico to acidify faster than other tropical and subtropical seas. The research team will incorporate observations from new large-scale surveys into oceanographic and statistical models that predict variation in ocean acidification over space and time.
Benefits of our work
The outcomes of this project will meet the long-term goal of optimizing ocean acidification monitoring in the Northwestern Gulf of Mexico and will document methodology that can be used in similar efforts in the future. This project will examine an area in the poorly understood Gulf of Mexico Large Marine Ecosystem, produce the first ever high-resolution dataset in surface and subsurface waters, and direct the future deployment of in-situ monitoring devices in this ecologically and economically important region.

ADAPTING TO OCEAN ACIDIFICATION

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:

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

REDUCING OUR CARBON FOOTPRINT

50 more ways to reduce your carbon footprint >

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

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
