![Page 4: Science to Support Management Decisions Related to Hypoxia in the Northern Gulf of Mexico and Water Quality in the Mississippi River Basin Herb Buxton,](https://reader036.vdocuments.mx/reader036/viewer/2022081511/56649cd75503460f9499f18d/html5/thumbnails/4.jpg)
The Science Strategy
A strategy to provide and maintain the scientific information needed to implement the adaptive management framework defined in the Action Plan.
![Page 5: Science to Support Management Decisions Related to Hypoxia in the Northern Gulf of Mexico and Water Quality in the Mississippi River Basin Herb Buxton,](https://reader036.vdocuments.mx/reader036/viewer/2022081511/56649cd75503460f9499f18d/html5/thumbnails/5.jpg)
• Management Implementation (Improved), • Monitoring, • Interpretation (including modeling),• Periodic Reporting (including public education), and • Research to improve knowledge and methods.
Adaptive Management
![Page 6: Science to Support Management Decisions Related to Hypoxia in the Northern Gulf of Mexico and Water Quality in the Mississippi River Basin Herb Buxton,](https://reader036.vdocuments.mx/reader036/viewer/2022081511/56649cd75503460f9499f18d/html5/thumbnails/6.jpg)
Our Tasks
• Review the Management Questions.
• Compile information on existing activities that contribute to essential monitoring, modeling and research activities;
• Identify information gaps and the activities needed to fill those gaps; and
• Identify coordination mechanisms to assure that information is gathered and delivered to support decision-making.

Management Questions
THE WATERSHED
What are the major sources and causes of excess nutrients within the Mississippi River Basin?
![Page 8: Science to Support Management Decisions Related to Hypoxia in the Northern Gulf of Mexico and Water Quality in the Mississippi River Basin Herb Buxton,](https://reader036.vdocuments.mx/reader036/viewer/2022081511/56649cd75503460f9499f18d/html5/thumbnails/8.jpg)
Management Questions
THE GULF
How are Gulf hypoxia and the associated adverse effects exacerbated by specific causal factors and what are the determining mechanisms?
![Page 9: Science to Support Management Decisions Related to Hypoxia in the Northern Gulf of Mexico and Water Quality in the Mississippi River Basin Herb Buxton,](https://reader036.vdocuments.mx/reader036/viewer/2022081511/56649cd75503460f9499f18d/html5/thumbnails/9.jpg)
Management Questions
SOCIAL AND ECONOMIC
What are the social and economic impacts of deterioration in water quality (nutrients) in the Mississippi Basin and increased hypoxia in the Gulf of Mexico?

Guiding Principles
• Adaptive Management.
• Design monitoring to serve sub-basin management implementation strategies.
• Make maximum use of all ongoing activities.

Guiding Principles
• Consider all potential causal and mitigating factors.
• Reduce uncertainties in measurements of adverse effects, causal factors, and underlying processes.
• Design monitoring activities to support modeling and other planned interpretations.

Guiding Principles
• Modeling should extrapolate monitoring at representative sites across the Basin.
• Periodic interpretations and reporting.

What we do not expect to be doing?
• Interpreting or reinterpreting data.
• Evaluating contributions of various nutrient sources.
• Debating the relative importance of causal factors of Hypoxia.
• Discussing the best management actions to be taken.

What we expect to be doing?
Designing a Strategy that:• Best facilitates those activities.• Is open to changes in approach
dictated by new understanding.• Identifies and addresses areas of
greatest scientific uncertainty.• Identifies areas of greatest
resource needs.
