Reference points for the global analysis
First Global Assessment
• 171 countries/territories
• All waters within EEZs
• >100 data layers
Some key messages/results
1. Index provides a portfolio perspective
2. Sustainability fundamental to, and operationalized in, the Index
3. Human benefits central to Index
4. Different perspectives incorporated
Portfolio Perspective: many ways to get a score

Accounting for different perspectives: weighting goals by value sets
• People care about different aspects of the ocean
• These differences are really important to understand and capture if management is to be effective
All goals are presumed equally important
Extractive goals are presumed more important
OHI: Science to Action
Summary
• Transparent, quantitative, ‘divable’, scalable, flexible, responsive, synthetic, target-driven, best available information
