Episode notes
Ice Density and Buoyancy
- Ice is less dense than water, with glacial ice being even denser due to compression.
- This density difference causes icebergs to float with only a fraction visible above water.
Iceberg Behavior and Color
- Icebergs can roll over without warning, changing their appearance and posing dangers.
- An iceberg's color can vary from blue to white to green depending on age and composition.
Iceberg Lifespan and Melting
- Icebergs, formed from compressed glacial ice, can last from 3-6 years or up to 50 in colder regions.
- They melt due to warmer waters and collisions, sometimes explosively due to thermal shock.
