If you were ever to get two activities that were diametrically opposed, it would be surfing and painting. We’ll speak with artist and surfer Henry Jock Walker about how he has managed to combine his two passions in more ways than one, and an upcoming online session at the Substation you will no doubt enjoy. Then we cross to Perth to chat with Dr Mark Meekan from the Australian Institute of Marine Sciences about how an extraordinary radioactive legacy of the Cold War’s nuclear arms race has led to an accurate new aging technique for whale sharks. Plus, Jeff Maynard’s Soundwaves saves the world again! This week we address the elephant in the semi-locked down room and find a way forward through 1950s movies and sea monsters.
