Blue Dot: Icebergs as a resource: how floating mountains of ice can be harvested for freshwater

A Weith

We delve into the world of iceberg science and the latest ideas on using them as sources of freshwater for the future as Dave interviews Ohio State University Professor Matthew Birkhold, author of Chasing Icebergs: How Frozen Freshwater Can Save The Planet. 

Birkhold looks at the history of icebergs from Captain James Cook using them to supply fresh water to his crew during their 18th-century explorations to the RMS Titanic disaster and the formation of the International Ice Patrol.

We discuss how technology that now exists can be used to harvest icebergs to provide freshwater to places that are in dire need of it like South Africa. Just like icebergs themselves, there's a whole lot more beneath the surface to delve into!
