A Hole in the Bottom of the Sea

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.

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.

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.

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

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