BBC Radio 4 is currently running a four part series “Oceans: what lies beneath” in which the author and broadcaster Gabrielle Walker “looks at how little we understand the waters on which human life depends, and talks to the scientists who are making some extraordinary discoveries deep beneath the ocean waves”. The four parts are titled “Ocean Life”, “The Deep”, “Ocean Resources” and “Oceans and Climate”. Each episode is 30 minutes long and can be listened to online at the BBC Radio 4 Oceans webpage.
