The Ocean Health Dashboard is a personal project built out of a genuine interest in the ocean and what the data tells us about its evolution. The goal is simple: make 33 years of ocean science explorable by anyone, without needing a scientific background to understand what's happening.

Temperature, salinity and pH are three of the most telling indicators of ocean health. Watching them shift across decades — year by year, season by season — is a sobering reminder of how much the ocean has already changed, and how much it still absorbs on our behalf.

• Copernicus Marine Service (CMEMS): GLORYS12 physics reanalysis (temperature, salinity)
• CMEMS PISCES BGC: Biogeochemical model reanalysis (ocean pH)
• NASA Aquarius / ESA SMOS: Satellite salinity cross-validation
• SOCAT v2023 / GOA-ON: Surface ocean CO₂ and pH observation network
• Argo Float Network: In-situ BGC profiling floats
