| # Golden Tide / Sargassum | |
| Golden tide is a floating vegetation-like target. It shares confusion sources | |
| with green tide but may have different color, texture, and morphology. | |
| ## Required Context | |
| - Treat unlabeled ecological elements as ignore, not as negatives. | |
| - Keep original scale metadata because raft-like texture and floating patches | |
| change strongly with resolution. | |
