Announcing 6 awards to help U.S. coastal communities adapt to ocean acidification

We are excited to announce almost $3 million for six awards dedicated to Regional Resiliency and Vulnerability Assessments (RVA). The projects support collaborative projects across the United States to advance our understanding of how ocean and coastal acidification affect human communities and coastal economies.

The RVA program’s central goal is to move beyond studying changing ocean chemistry toward delivering actionable information. This will help local, state, and Tribal communities develop strategies, protect vital resources, and build community resilience. The newly funded projects will deliver tailored tools and strategies to address regional challenges.

The newly funded projects are:

Synthesizing OA information and engaging local knowledge to enhance the efficiency of resiliency planning in southeast Alaska

The team will collaborate with rural communities, Tribes, and commercial fishing organizations to create decision-support tools that combine oceanographic data with local knowledge. These tools like maps and models will help rural Alaskans, whose subsistence, food security, and culture rely on the marine environment, assess and respond to the cultural and economic impacts of changing ocean conditions.

Integrating exposure and community vulnerability to develop adaptation strategies to mitigate acidification impacts in the Chesapeake Bay region

Researchers will assess how ocean and coastal acidification risks affect the rapidly growing shellfish aquaculture industry across Virginia’s Chesapeake Bay and Atlantic seaside. The resulting public-facing dashboard will feature real-time and forecast water condition and shellfish growth data, providing shellfish growers and harvesters with essential information to plan for future environmental changes.

Collaborating with fishing communities to adapt: co-developing actionable strategies for Atlantic sea scallop fishing communities

Focused on the Atlantic Sea Scallop fishery, one of the most economically valuable in the US, this project will integrate oceanographic modeling, industry engagement, and socio-economic research to develop actionable adaptation strategies. Expected outcomes include seasonal forecasts for decision-making and policy recommendations to mitigate impacts on the industry.

OCEAN: Ocean Chemistry and Ecosystem Assessment for Networks of Resilience

This foundational work in coastal Louisiana will engage Indigenous communities, seafood industry leaders, and policymakers through community workshops to identify key research and data needs for a future regional vulnerability assessment in the Gulf of America. The project’s outcomes will directly inform local, state, and national adaptation planning, which is essential to protecting coastal Louisiana’s multi-billion-dollar seafood industry and traditional livelihoods.

Data synthesis and community engagement to define the scope of a regional ocean acidification vulnerability assessment in Casco Bay, Maine

This project will focus on Maine’s shellfisheries in Casco Bay by working directly with wild harvesters, aquaculture producers, and decision-makers to define the impacts of acidification and the information needed for adaptation. The effort will create a new resilience assessment framework, which will strengthen informed risk assessment and decision-making for the communities that rely on Maine’s shellfisheries.

Development of OA data and model products to inform ocean change adaptation, resilience, and mitigation planning by tribal and other Olympic Coast coastal resource managers

This project directly supports Coastal Treaty Tribes in Washington by co-designing and synthesizing new data and forecast products focused on key species like Dungeness crab and Pacific halibut. Building on previous work, it ensures that marine resource users and managers on the Olympic Coast have practical, up-to-date tools to plan for a changing ocean.

Effects of ocean acidification and temperature on Alaskan crabs

Long-term declines of red king crab in Bristol Bay, Alaska may be partially attributed to ocean acidification conditions. These impacts may be partially responsible for the fishery closures during the 2021–2022 and 2022–2023 seasons. Researchers found that ocean acidification negatively impacts Alaskan crabs generally by changing physiological processes, decreasing growth, increasing death rates and reducing shell thickness. Funded by the Ocean Acidification Program, scientists at the Alaska Fisheries Science Center continue to investigate the responses of early life history stages and study the potential of various Alaska crabs to acclimate to changing conditions. Results will inform models that will use the parameters studied to predict the effects of future ocean acidification on the populations of red king crab in Bristol Bay as well as on the fisheries that depend on them. Fishery managers will better be able to anticipate and manage stocks if changing ocean chemistry affects stock productivity and thus the maximum sustainable yield.

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.

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

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
