OCEAN ACIDIFICATION INFORMATION FOR ACTION: A USER GUIDE
Ocean acidification researchers produce targeted information that can help policymakers, resource managers, stakeholders, and communities better comprehend impacts of OA on marine resources, and enable them to identify the most appropriate mitigation or adaptation actions to minimize and address the effects of OA.
There are several variables at play when policy makers, marine managers, or stakeholders are determining which data to prioritize to guide decision-making. By exploring global projects that utilize OA information, this webpage encourages you to reflect on the lessons learned in these projects as you refine your own goals and develop potential actions.
As you work your way through each section, we hope you will be inspired to start conversations that will broaden your understanding of how to achieve your goals, and establish lasting connections within the broader OA community. If you have questions at any point in your journey, join the OARS Community of Practice to connect with subject-matter experts in our Q&A Forum.
WHAT ROLE DO YOU PLAY?
-
Ocean acidification researchers investigate how seawater chemistry is changing, what is driving these changes, and how these changes may impact coastal ecosystems, marine species, human societies, and the planet as a whole.
The data, evidence, and information provided by the OARS scientific community is the foundation for any effort to understand, manage, mitigate or adapt to the changes our ocean is experiencing.
-
Management of OA requires a nuanced understanding of ocean and coastal acidification and the relationships —or tradeoffs— between establishing new management tools and leveraging existing programs.
Policymakers and marine resource managers collaborate to identify and prioritize gaps in knowledge that will inform local intervention strategies and provide managers a more complete picture of local drivers, conditions, risks and solutions.
-
Many communities around the globe are worried about the changes they are seeing in the ocean's health because it impacts them personally. Stakeholders from all walks of life can connect over shared concerns and work together to monitor and respond to the threat of ocean acidification and the mounting climate emergency.
HOW CAN OCEAN ACIDIFICATION INFORMATION SERVE YOU?
The right OA information can help policymakers, resource managers, and community members understand the impacts of OA on marine resources and identify the most appropriate mitigation or adaptation actions to minimize and address the effect of OA.
However, achieving impactful outcomes through appropriate policy goals and management tools requires a better understanding of the data and conditions required for leveraging the correct tools to address a specific problem.
To encourage a diversity of OA actions across different scales, OARS Outcome #2 has outlined 6 key decision-making categories. These categories provide a framework for identifying your OA information needs for specific mitigation and adaptation actions.
To get started, identify the type of issue you want to address from the six categories below. Within each category, you’ll find a link to a featured case study that thoughtfully examines factors that informed a place-based priority project. Case studies also examine lessons learned, challenges and critical information gaps that both OA researchers and users of OA information can draw upon in shaping future projects.
1. Impacts of CO2 emissions on human and ocean health and resources
You are interested in evaluating the impacts of carbon dioxide emissions, by documenting changes that are occurring in your local environment and/or to inform the ways these changes may pose social, economic, or cultural risk to human communities who rely on impacted resources and ecosystems.
4. Reduction of land-based pollution
You are interested in advancing local remediation of cumulative impacts and adaptation strategies through reduction of land-based pollution.
2. Food security and resilience of seafood economies
You are interested in increasing food security and resilience of seafood economies and coastal communities by advancing understanding about the effects of OA on key seafood species and exploring adaptation strategies for aquaculture and food industries.
5. Nature-based coastal solutions
You are interested in deploying blue carbon sequestration projects or increasing ecosystem resilience with marine and coastal habitats.
3. Best applications of marine management tools
You are interested in utilizing the best applications of marine management tools such as guiding targeted regulations, seasonal closures, or conservation measures, to improve sustainable ocean planning.
6. Marine Carbon Dioxide Removal
You are interested in assessing the potential risks, benefits, and monitoring, and evaluation needs of various marine carbon dioxide removal strategies.
Which OA research activities best serve your needs?
In every region of the world, OA research activities of all shapes and sizes are increasing or strengthening OA knowledge for specific actions in mitigation, adaptation and restoration. These activities include, but are not limited to:
-
Building baselines to measure coastal variability and trends in physical and chemical parameters.
Enhancing climate response and preparedness and strengthening predictive models.
Reporting global trends in ocean warming, acidification and deoxygenation, obtained by modeling, to IPCC, UN SDG 14.3.1 or other regional climate-ocean observing bodies.
-
Conducting species-specific research to determine vulnerability and adaptation potential particular for ecosystem engineers, foundation species, or species of economic or cultural importance.
Improving knowledge of biological impacts to marine species and ecosystem functioning within the region.
Hindcasting, forecasting, and modeling of ocean and coastal conditions to better integrate environmental and biological data into fisheries stock assessments to promote adaptive management.
Using satellite observations to help predict exposure of corrosive conditions, undersaturation, or prolonged temperature increases, and illuminate locations or episodes of increased stress or vulnerability.
Performing lab research and experimentation to examine biological and physiological impacts to keystone species, and to examine adaptation potential and thresholds of those species.
Carrying out lab research and experimentation to examine multiple stressors on ecosystem function and other drivers.
-
Conducting nationwide or regional vulnerability assessment to identify the risks that ocean warming, acidification, and loss of oxygen pose to socio-economic-systems: including coastal and marine resources and ecosystem services, the coastal economy, and the social dynamics of coastal communities.
Conducting ecosystem vulnerability assessments (to move beyond species-specific studies).
Integrating projections to inform robust climate risk or vulnerability assessments.
Utilizing projections to inform policy and financing needs associated with risk and vulnerability assessments.
-
Generating information to underpin calls for urgent and drastic reductions of CO2 emissions.
Carrying out research to identify: (1) place-based wild (endemic) species, community resources or commercial practices that may be at risk; (2) areas where additional management, conservation, restoration, or regulation schemes are needed to support resilience; (3) techniques or actions that could remediate harm or build resilience.
Identifying local sources of land-based pollution like nutrients (including nitrates) that contribute to OA and eutrophication.
Performing place-based monitoring and research to evaluate the sequestration potential of blue carbon ecosystems by applying scientifically supported methodologies accounting for the potential sequestration potential of blue carbon ecosystems.
Conducting place-based monitoring & research to evaluate where and how marine vegetation and coastal wetlands are beneficial for remediating impacts of OA and support ecosystem resilience.
Mapping coastal and marine habitat to determine the spatial extent of vulnerable and/or exposed ecosystems.
Exploring aquaculture techniques that aim to predict and mitigate corrosive conditions.
Outlining, prioritizing, and conducting the research and evaluation needed to assess the implications of different mCDR approaches/ techniques.
Including ocean acidification in appropriate management strategies, policies or legislation.
* Any such effort must be undertaken in parallel to engaging stakeholders and end-users who must agree to, co-design and apply mitigation and adaptation actions.
