Episode notes
Deep-Sea Worm Reproduction
- A bizarre deep-sea worm lives inside sponges and reproduces uniquely.
- It grows branched tails with eyes and gonads that detach and swim to the surface to mate.
Accidental Oceanography
- Helen Czerski's physics background led her to oceanography through bubbles and acoustics.
- She emphasizes the ocean's complexity and the lack of attention it receives in traditional physics.
Ocean Stratification
- Ocean layers are determined by density, with small density differences creating stratification.
- These layers, influenced by temperature and salinity, affect how water moves and carries its chemical signature.
