ICEBERG IMAGE COMPARISON NOTES
Yenra | October 11, 2026
Guide: https://yenra.com/iceberg-pictures/
Purpose: compare a documented iceberg fragment in two or more images.
1. For each image record acquisition date/time (and timezone), publication date,
   provider/source URL, sensor, processing, projection, scale/resolution, location,
   fragment label, and obscured areas. Keep uncertain entries marked uncertain.
Image A:
Image B:
2. Explain how you established that the same fragment is present in both.
Identity evidence:
3. Describe visible changes before explaining causes. Use compatible map units.
Observation:
Measurement method and uncertainty:
4. If measuring displacement, record elapsed time and matched positions.
   Fictional example: 30 km net displacement / 6 days = 5 km/day average net
   displacement rate. Actual traveled distance can be longer; thickness is needed
   to estimate volume. A changed bounding box can reflect rotation.
Result and units:
5. Separate optical observations from biological or other environmental evidence.
Interpretation:
