Ultramarine: the science of our oceans and waterwaysEarth's alien oceanWe travel nearly ten kilometres beneath the surface of our own planet to explore one of the most extraordinary discoveries in modern science.For decades, the search for extraterrestrial life has focused on distant planets and far-off stars. But some of the most compelling clues may be hiding in the deepest trenches of Earth’s oceans. In total darkness, under crushing pressure and without any sunlight, scientists have discovered thriving ecosystems powered not by light, but by chemistry.Host David Boldeman and ConnectSci journalist Evrim Yazgin unpack how these deep-sea organisms survive using ch...

Ultramarine: the science of our oceans and waterwaysDid we accidentally design our cities for mosquitoes?Mosquitoes are usually framed as pests and disease carriers. But what if they are simply one of the most successful species at adapting to the environments we have built?In this episode Ultramarine, David Boldeman is joined by medical entomologist Dr Véronique Paris to explore the hidden water systems inside our cities and how they shape mosquito life.Véronique is a Research Fellow in Medical Entomology and Vector Population Control, at the University of Melbourne: https://www.instagram.com/mozzienique/This podcast is brought to you by ConnectSci, th...

Ultramarine: the science of our oceans and waterwaysThe impact of shifting ocean currentsOcean currents are the hidden systems that regulate Earth’s climate, moving heat and energy around the planet. But as the ocean warms, those currents are beginning to shift, with major consequences for Australia.In this episode of the Ultramarine, science journalist Ellen Phiddian explains how ocean currents work, how scientists track their movement, and why predicting their future is so complex. The conversation explores changes already being observed, from the Antarctic Circumpolar Current to the East Australian Current pushing further south along Australia’s east coast.Together, the episode unpacks what scientists know...

Ultramarine: the science of our oceans and waterwaysThe Strange Physics of TidesDavid Boldeman is joined by science journalist Ellen Phiddian to explore the strange and often misunderstood physics of tides. The conversation unpacks why most coastlines experience two tides a day, why tidal behaviour varies so dramatically around the world, and what tide charts are actually measuring. Along the way, they examine spring and king tides, the influence of geography and ocean shape, and how tidal forces affect not just the oceans, but the Earth and Moon over deep time including the possibility that tides played a role in the origins of life.For the latest science n...

Ultramarine: the science of our oceans and waterwaysHow do we measure sea level rise?This episode explains how sea level rise is measured — not just that it’s happening. It demystifies the tools, the data, and the validation process that sit behind one of the most talked-about climate metrics.Sea level is a baseline measurement that underpins city planning, infrastructure design, flood risk modelling, and long-term coastal decision-making. Understanding how we know builds trust in what we know.Science journalist Ellen Phiddian joins host David Boldeman to guide you through the measurement process, how evidence is tested, and how journalists assess confidence in scientific claims.

Astronomy Daily: Space News UpdatesAnomalies in India's Launch| SpaceX's Starlink Expansion| Cosmic Dawn Signals: Your Daily Space UpdateIn today’s episode of Astronomy Daily, Anna and Avery take you from rocket pads on Earth to the farthest corners of the cosmos. We cover India’s latest PSLV launch and its unexpected anomaly, the FCC’s green light for thousands more Starlink Gen2 satellites, NASA’s Pandora mission to decode exoplanet atmospheres, a fleeting signal from a supernova that exploded 13 billion years ago, a breakthrough in understanding the Sun’s most violent flares, and the surprising discovery of a barred spiral galaxy in the early Universe. It’s an episode where orbital mechanics meet cosmic archaeology — with a dash of solar...

Ultramarine: the science of our oceans and waterwaysHow you can help save the Great Barrier ReefIn this Ultramarine episode of the Connect Sci Podcast, host David Boldeman speaks with Sean Daly from Citizens of the Reef about how students, teachers, and everyday Australians can play a real role in protecting the Great Barrier Reef.Sean explains the major threats facing coral reefs — especially climate change and outbreaks of Crown-of-Thorns Starfish — and why traditional scientific monitoring can only cover a small fraction of this vast marine system. He talks about the Great Reef Census, a global citizen-science project where divers, tourists, schools, and volunteers photograph and analyse reef images to build the most...
