Tiny stones in fish hold clues to help restore populations
Geological records help forecast escalating coastal hazards
Tiny animals dominate the undersea soundscape
NATO seeks advice to avoid collateral environmental damage
Scientists devise way to relay sound signals under water
These scientists, working on coral reefs, fish ecology, or seafloor topography, require uninterrupted lengths of time or close work in small areas, which are impossible to do by free diving or snorkeling. Scuba allows them time to observe and the experience of being in the environment yields insights beyond experimental results.
