Summary: South Africa's annual Sardine Run is about to kick off. In this week's ambient audio podcast, we bring you some of the diverse sounds of this phenomenal event - from the peaceful, rolling waves in Port St Johns to the abrasive call of Cape gannets and the loud splashes as they dive into the water (make sure you listen out for the loud thud of a shark swimming straight into one of our cameramen!) For more info on this spectacular marine event, visit the Earth-Touch blog.
