| # Oil Spill | |
| Oil spill extraction is often sensor-specific. SAR imagery is especially useful, | |
| but dark slicks can be confused with low wind, biogenic films, rain cells, and | |
| calm water. | |
| ## Required Context | |
| - Sensor type must be explicit. | |
| - Use hard negatives for natural dark water phenomena. | |
| - Do not treat unlabeled water anomalies as definite negatives. | |
