Davos Diving in Norway

Davos is a South African-born diver who has been studying orcas in this region for the last seven winters. He uses his radio to keep in touch with nearby researchers, so he can stay attuned to the animal's behaviours and help locate individual members of the pods. I never knew how powerful an orcapod sonar pulse could be until I got into the water and felt one reverberate deep in my chest,. like the notes from a bass guitar at a rock concert.
