Episode notes
Keep Regular Contact And Abort If Silent
- Maintain strict communication and abort dives if contact fails: subs must check in with surface every 15 minutes.
- Follow regulations and safety protocols; deep dives are not 'cowboy' operations.
From Volunteer Guide To Marine Scientist
- Todd's first fish job was as a volunteer tour guide at AQWA, which led to paid roles and diving with sharks.
- That early work let him combine university learning with hands-on animal access and communication skills.
Finding Puffer Fish 'Crop Circles' On Pipelines
- Todd found puffer-fish 'crop circles' on pipelines in WA, matching remarkable structures filmed in Japan.
