Dwight Gledhill

Dwight Gledhill, Ph.D.

Deputy Director

Dr. Dwight Gledhill serves as Deputy Director of the NOAA Ocean Acidification Program headquartered in Silver Spring, MD.  Dwight has served in this capacity since nearly the start of the program and even worked towards the creation of a cross-agency initiative on ocean acidification in the years prior to the Federal Ocean Acidification Research and Monitoring Act (FOARAM).  Since the program’s inception, he has worked to ensure the programs research portfolio remains transdisciplinary, world class, and responsive the needs of NOAA’s stakeholders. An Army veteran of Operation Desert Storm, Gledhill received his M.S. and Ph.D. from the Department of Oceanography at Texas A&M University in 2005 where he researched carbonate mineral kinetics in complex electrolyte solutions as well the sediment biogeochemistry associated with methane clathrates (i.e. gas hydrates) in the Northern Gulf of Mexico. He joined NOAA as a 2005 Sea Grant Knauss Fellow at NOAA NESDIS Coral Reef Watch where he led the dev​elopment the first satellite-based estimates of ocean acidification in the Greater Caribbean Region.  Currently, Dwight is a member of several interagency working groups including the Interagency Working Group on Ocean Acidification (IWG-OA), Carbon Cycle Interagency Working Group (CC-IWG) and the Interagency Carbon Dioxide Removal Research Coordination (I-CDR-C) Work Stream. More recently Gledhill has been helping to lead the NOAA Carbon Dioxide Removal (CDR) Task Force engaged in formulating a cross-NOAA research strategy relevant to NOAA’s mission areas.

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
