Reef Life is the story of how Callum Roberts, Britain's pre-eminent marine conservation scientist, fell in love with coral reefs and embarked on a thirty-year career. He began as a young university student who had never been abroad, spending a summer helping to map the unknown reefs of Saudi Arabia. And from that moment, when Callum first cleared his mask, he's never looked back, moving on to survey Sharm El Sheikh, and from there diving and researching all over the world, including Australia's imperilled Great Barrier Reef and the more resilient reefs of the Caribbean. His stories are astonishing, lyrical and laced with a wonderful wry humour - and they allow us privileged access to, and understanding of, the science of our oceans and reefs.
