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.
