Earthquakes, extinctions & deep microbiology: the discoveries made by scientific ocean drilling with Dr Ron Hackney (opens the original)
Read excerpt
Pushing the frontiers of knowledge about our planet has never been so much fun! We've explored less of the ocean floor than we have the surface of Mars, so Dr Ron Hackney , director of ANZIC (the Australian New Zealand International Scientific Drilling Consortium), brought the ocean floor to us. Across three remarkable objects: a core from the fault that ruptured the 2011 Tōhoku earthquake; a set of microscopic radiolarian fossils; and the world-famous "day the dinosaurs died" core from the Gulf
The amazing chemistry of ocean sediments with Dr Stefan Loehr (opens the original)
Read excerpt
We've directly observed less than 0.001% of the seafloor — so what's really going on down there? In this episode, Dr Stefan Löhr (ARC Future Fellow at the Adelaide University, and researcher with the Centre for Critical Resources for the Future) makes the case that the ocean floor is anything but a passive dumping ground for eroded continents. This will reshape the way you view the ocean - who knew it was so dynamic! We trace marine weathering from a decades-old mystery in seawater chemistry, th

Critical Chromium: From Field Samples to Space Technology: How Do We Secure Supply? Exploring for critical chromium, from the ground up (to space!) Aerospace alloys, industrial protective coatings, stainless steel - chromium is literally everywhere in critical technology and in our kitchens, yet global supplies are stretched. So how do you hunt for chromium deposits? In this episode we journey through the world of chromium and find the answer takes us from dusty fieldwork in Odisha, India, to sa
Carbonatites: to REE or not to REE? (opens the original)
Read excerpt
💎 Carbonatites: To REE or Not to REE? Earth's strangest magma is carbonate-rich, comes from the mantle, and there's only ONE erupting on the planet right now. It's called a carbonatite, a rare igneous rock that hosts the world's largest rare earth element resources. But here's the plot twist: only about 10% of the ~600 carbonatites that have been found are actually rich in rare earths. So how do we find the REE-bearing ones? Dr Shirley Hu and Dr Louise Schoneveld from CSIRO are using geochemistr
This critical metal is only found in mine waste? Dr Olivia Mejias Gonzalez on indium... (opens the original)

✨ The Weirdest Critical Metal You've Never Heard Of: Indium, Mine Waste & the Hunt for Hidden SuppliesYou've touched it hundreds of times. It's in your phone screen, your laptop, your solar panels, your TV. But unless you're a obsessed with periodic table trivia, you probably have no idea what it is.Meet indium. Its a critical metal so rare, yet so essential. But here's the catch: there's basically no such thing as an indium mine.Today we're talking to the wonderful Dr Olivia Mejas-Gonzales, a r
