Enter a California coastal city to see nearby historical samples and a model prediction.
Project ocean conditions using linear trends from 2000–2021 data.
Sliders use real value ranges from 895k CalCOFI bottle samples.
| Label | O₂ (ml/L) | O₂ Sat | NO₃ (µM) |
|---|---|---|---|
| ✅ Healthy | ≥ 4.0 | ≥ 40% | ≤ 20 |
| ⚠️ Stressed | 1.4–4.0 | ≥ 40% | > 20 |
| 🚨 Critical | < 1.4 | < 40% | any |
O₂ excluded from inputs — prediction uses temperature, salinity, nutrients, depth, chlorophyll.

895,440 samples across 72 years
Track how ocean health has evolved from 1949 to today. Each band shows how many samples fall into healthy, stressed, or critical conditions each year.
Dots show yearly values, while the green line highlights the overall rolling trend.

Surface waters are mostly healthy, but stressed and critical conditions grow with depth.
Lower oxygen at deeper levels leads to stressed or hypoxic conditions for marine life.
Lower oxygen levels are strongly linked to stressed and critical conditions for marine life.
