Coastal scientist at UNSW, Dr Rob Brander OAM, aka Dr Rip, comes onto Radio Marinara to talk about his new book, Dr Rip's Essential Beach Book: Everything you need to know about surf, sand and rips, a practical and comprehensive guide to beach safety when heading to the beach this summer.

They talk about his trajectory from studying beaches in Canada to Australia, how he became known as 'Dr Rip', his work as a 'coastal geomorphologist' (the study of the processes and traits of waves, current, sand bars, and anything to do with the coast) and addresses the most important question: 'how do you spot a rip?'
