A Hole in the Bottom of the Sea

Dolphins or Dust? What would you choose? Scientists Rosie Sheward and Ann Dunlea talk to Claire about their excitement over the tiny things that can be found in sediment, and what they can tell us about past climate.

Science is a process supposed to eliminate all subjectivity so that we can truly understand the nature of the world around us. But science is a process created by people, and carried out by people! How does being at sea for long times affect people emotionally, and how can they overcome this to collaborate to advance science in a truly significant way? Claire speaks to Debbie Thomas, Kevin Grigar, Dan Marone and Ann Dunlea in this final episode of This is Science: Expedition 378.

'Core on Deck, Core on Deck' a phrase that kicks off a hive of activity on the JOIDES Resolution. Claire talks to JR tech Dan Marone about the choreography of the core flow through the labs, and to scientists Chris Hollis and Ann Dunlea about processing core samples.

Geological time boggles the brain. Millions of years in the past the Earth looked very different than it does today. But the past is in the past, right, why dig it up? Well it might help for the pickle we seem to be getting ourselves in to. We can't run whole Earth climate experiments but we can look back at previous ones to ask questions about what might be to come. Scientists Debbie Thomas and Laura Haynes explain to Claire why Expedition 378 is focusing on the climate during the Paleogene period.

Journeying to a remote area in the South Pacific Ocean to drill into the seabed floor to recover sediments for science - clever idea or crazy idea? What about the idea of drilling to the Earth's Mantle at a time when no proper equipment existed?! In this episode Claire talks to Lindy Newman about the amazing story behind how ocean drilling for science got started.

What happens when you put 118 people on a boat and send them off to the South Pacific Ocean to drill holes in the seabed floor? And what are they doing there in the first place?! New podcast mini series coming soon - This is Science: Expedition 378. Learn about life, science and adventures on the high seas.

Ginny and Jason search for life, hundreds of meters below the seafloor.

Follow a sample of rock as it is analyzed by the many scientists in the onboard labs of the JOIDES Resolution.

An episode consisting of three stores: an idea that no one believed, how to start the hole itself, and an expedition of tragedy and discovery.

Media attention reveals public concern over expedition 360 and a brief introduction to the JOIDES Resolution and a couple of the people who call it home.

What is the mantle and why do we want to get our hands on it so badly? On this first episode we talk to chief scientist Henry Dick and staff scientist Peter Blum about the history leading up to expedition 360 and what we might learn from the next two months. Correction: this episode incorrectly states that seismic waves travel faster in denser rocks. The correct relationship is seismic waves travel faster in stiffer (more rigid and incompressible) rocks.
