Episode notes
First Deep-Sea Deployment
- Alycia Smith, a deep-sea ecologist, recounts her first deep-sea research deployment in the North Pacific.
- She describes the nerve-wracking process of deploying and retrieving the respirometer lander.
Unexpected Oxygen Increase
- During her first deployment, Smith observed an unexpected increase in oxygen levels in the deep sea, contrary to established scientific understanding.
- Initially, she and her team suspected equipment malfunction, but multiple sensors confirmed the unusual readings.
Dark Oxygen Discovery
- Scientists discovered "dark oxygen" being produced without sunlight at the bottom of the ocean.
- This challenges our understanding of oxygen production and raises questions about life's origins and potential for extraterrestrial life.
