Dr Julie Mondon from Deakin University has just come back from a stint in Antarctica doing research into impact of sewage produced by researchers and staff on Australia's Antarctic bases. She'll join us to talk about her research and what she found.

Many of us are pretty confident we know the coastline around Port Phillip Bay and Westernport, but none more so than Graham Patterson. He walked the entire 580km coastline of both embayments, including Phillip and French Islands, and then put all of his observations and research into two fabulous guides. We'll be speaking with Graham about what inspires him so much about Port Phillip and Westernport, and what's in these great new publications.

Plus the latest from the world of marine science, and we celebrate International Women's Day with a tribute to marine research pioneer and early shark conservationist champion, the recently departed Professor Eugenie Clark.
