The Great Pacific Garbage Patch
Covering roughly 1.6 million square kilometers, the GPGP contains an estimated 79,000 tonnes of plastic. Notably, nearly 46% of the mass is comprised of discarded fishing gear (ghost nets).
Plastic Degradation Estimator
Data & Modeling
| Size Class | Estimated Particle Count (Trillions) | Estimated Mass (Tonnes) |
|---|---|---|
| Microplastics (0.05 - 0.5cm) | 51.2 | 268,000 |
| Mesoplastics (0.5 - 5cm) | 0.005 | 21,000 |
| Macroplastics (>5cm) | 0.001 | 20,000 |
Common Misconceptions
A frequent error in media interpretation is confusing localized transient effects with global secular trends. The figures demonstrated here isolate the multi-decadal signal from seasonal noise.
Frequently Asked Questions
Is this reversible?
On human timescales, highly unlikely. The thermal inertia of the ocean means impacts will persist for centuries even if emissions cease immediately.
How accurate are these figures?
Based on the latest AR6 synthesis and prevailing primary literature. Uncertainties are inherent in coupled non-linear climate models.
