Meteorology · Ice — Iceberg vs Growler
A 'growler' is:
- AA warm ocean current
- BA very large tabular iceberg
- CA type of sea fog
- DA small piece of glacial ice, awash and hard to detect by eye or radar, posing a hazard to vessels✓ Correct
Explanation
Growlers are small, often dark or translucent fragments of glacial ice that float nearly awash, making them very hard to see and poor radar targets, yet massive enough to hole a hull. 'Bergy bits' are somewhat larger. Vigilance and reduced speed are essential in iceberg waters.
