Chapters
The RMS Titanic is disappearing — and in just 20-30 years, the wreck may be completely gone. But it's not just time and water doing the damage. Iron-loving bacteria are literally eating the ship! In this video, we explore the fascinating science behind how microbes, galvanic corrosion, and deep-sea conditions are dissolving the most famous shipwreck in history.
Learn about Halomonas titanicae — a bacteria discovered IN the Titanic's rusticles — biofilms, galvanic corrosion between iron and brass, and why these same microbes could one day be used to recycle metal from ocean structures.
📚 Topics Covered:
- The discovery of the Titanic wreck in 1985
- Deep-sea life: microbes that thrive under extreme pressure
- Biofilms: how bacteria colonize the wreck
- Iron-eating bacteria and rusticles
- Halomonas titanicae: the bacteria named after the Titanic
- Galvanic corrosion: how brass accelerates iron rusting
- Could iron-eating microbes be useful for metal recycling?
