Episode description
James Bradley, an award winning author of fiction has just released his latest title, a non-fiction book entitled Deep Water: the world in the ocean. It is a "blend of history, nature writing, and environmental science" giving readers insights into the mysteries of the ocean and "humanity's complex connections to the seas." In one passage, James describes the surprisingly complex life cycle of Antarctic krill, its vast biomass often visible from space, and the source of energy for so many species including fish, penguins, and whales. Yet krill are declining in key areas that threaten the entire polar food chain for reasons from the obvious, such as overfishing in critical habits, to the species' more complicated and dependent relationship on winter sea ice. Sea ice that has dramatically declined in recent years due to climate change. The book celebrates the countless researchers past and present working to unlock the ocean's deepest secrets.
