Episode notes
SS United States Sinking
- The SS United States, a massive 1950s ocean liner, is being sunk to create an artificial reef off Florida's coast.
- This aims to boost biodiversity, attract tourists, and divert divers from natural reefs.
Ship Reefing Process
- Preparing a ship for reefing takes 1.5 years, involving removing contaminants like metals, plastics, oils, and chemicals.
- Explosives sink the cleaned ship, which costs around $10 million for the SS United States.
Tire Reef Failure
- In the 1970s, 3 million tires were sunk as an artificial reef, but the project failed.
- It released toxins, the tires weren't anchored, and they damaged coral.
