Modeling and Forecasting OA and HABs to meet stakeholders needs – Regional Perspectives

Corrosive, hypoxic, and harmful algal bloom (HAB) events in coastal waters are of increasing
concern to local fisheries and managers. Many important species around the country in coastal
waters are currently experiencing or are expected to feel effects of ocean acidification and
harmful algal blooms, both of which have the potential to affect not only marine species health
but also human health. HAB and ocean acidification (OA) and hypoxia distributions are often
patchy in both space and time, such that one area might experience a bloom or low dissolved
oxygen while a nearby area does not, and these conditions can change over the course of a day at
a single site. Rapid, timely, and spatially extensive detection and monitoring of HABs is vital for
public health and safety. Similarly, monitoring and forecasts of corrosive conditions are valuable
for advising shellfish growers. The collective ability to predict the co-occurrence of the intensity
of harmful algal blooms, hypoxic and corrosive conditions, as well as the spatial variability of
these conditions, alongside changes in their duration is of considerable benefit to managers.
Moreover, modeling work can enable scientists to evaluate triggers and possible synergies
between ocean acidification and HABs to investigate observationally and in the lab. This
presentation will include recent advances in modeling and forecasting of across different regions
in the U.S. Nearly all the coastal regions of the US are developing OA forecasts and these
systems span many habitats relevant to HABs. In some cases, the systems are used for other
forecasts including HABs. Along the U.S. West Coast, a mosaic of ocean modeling activities,
run as quasi-operational systems that provide numerous products pertaining to harmful algal
blooms, ocean acidification, and hypoxia. Along the U.S. Gulf and East coasts, modeling and
quasi-operational systems focus on hypoxia and HABs.

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
