S3 Ep7: Leading polar expeditions, with Ed Luke and Matthew Shepherd

A field guide is one of the most highly skilled and varied jobs in Antarctica. From accompanying scientists on expeditions, training their colleagues to survive on the ice and fixing sledges, there's never a dull day. Polar field guides Ed Luke and Matthew Shepherd talk to Nadia about life on the ice and extreme camping.  Produced in partnership with Boffin Media; cover photo by Ed Luke.
