Scientific Ocean Drilling

Hi, I’m Dr. Suzanne O’Connell. O'Connell, a geology professor at Wesleyan University is the educational liason aboard the JOIDES Rsolution for the current expedition.

You can also read her updates below about life (work and play) aboard the ship.


How do you study the Earth's crust below the ocean? Well, you use a drill. A very, very long drill attached to a boat floating free out in the middle of the ocean.

It's easy to study the Earth's crust if the samples you need come from here, on land. But if you need samples from the three-quarters of the Earth's surface covered by ocean, your options are fairly limited. That's where the Integrated Ocean Drilling Program (IODP) comes in. IODP is an international scientific partnership that drills into the sea floor to get samples to study.


Drilling deeper than ever before

What are these scientists looking for? Why are they trying to find this mysterious gabbro? And what is the MOHO anyways?
