| # Sea Ice | |
| Sea ice can be mapped from optical or SAR data, but the feature appearance changes | |
| with sensor, illumination, weather, and season. | |
| ## Required Context | |
| - Clouds, snow, bright land, and sea ice must not be collapsed into one class. | |
| - Sensor-specific normalization and augmentations are required. | |
