Ocean Acidification Levels (pH)
Lower pH indicates higher acidification - impacts coral and shellfish

Microplastic concentration by depth and location (particles/m³)
Fishing Pressure vs. Stock Sustainability
Each point represents a fish stock - position indicates sustainability status
Data Interconnections
Temperature ↔ Coral Health: Higher temperatures correlate with increased coral bleaching and mortality
Acidification ↔ Species: Lower pH reduces shellfish and coral populations
Pollution ↔ Biodiversity: Higher pollution density decreases overall biodiversity index
Fishing ↔ Species: Overfishing pressure directly impacts species population levels
Protected Areas ↔ Health: Higher protection correlates with improved ecosystem metrics
All Factors ↔ Overall Score: Combined weighted impact on ocean health score
