Rips claim an order of magnitude more lives than shark attacks in Australia, and are arguably the most dangerous facet of going to the beach.

Associate Professor Rob Brander, also known as Dr Rip, is a coastal geomorphologist who studies morphodynamics (hydrodynamics, sediment transport, morphology) of coastal systems, with a particular interest in rips and the safety of beachgoers. He runs a beach education program called Science of the Surf, and one of the cool things he does is publish a Rip of the month. You might like to read his book, Dr. Rip's Essential Beach Book, or check out the National Geographic documentary, Rip Current Heroes.

Coming into the summer, listen in as Rob lets you know how to spot a rip and what to do if you're caught in one.
