Episode notes
Shipwrecks Caused by Icebergs
- Josh Clark jokingly mentions the fictional sinking of the "William Carson" due to an iceberg.
- He then lists real ships sunk by icebergs, highlighting the danger they pose.
Iceberg Origins and Composition
- Icebergs are freshwater, originating from calving glaciers, not frozen seawater.
- Glaciers are packed snow that, over time, becomes dense, blue ice.
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.
