JOIDES Resolution: Courtesy Ocean Drilling Program

About 500 miles west of Costa Rica, scientists dug deep (and I mean DEEP) into the Earth’s crust. For the first time, layers of pristine igneous rock were retrieved. Their findings included a dark rock called gabbro. Gabbro is an igneous rock formed when molten magma is trapped underneath the Earth’s surface, cools and forms a crystalline mass.

JOIDES Resolution, the drill ship, bored nearly a mile into our planet’s oceanic crust recovering a complete stratified core of the overlaying crust in the Pacific Ocean. Studying gabbro along with crust sections will better inform scientists about the processes pertaining to crust formation and structure, plate tectonics, mountain formation as well as earthquake and volcano triggers.

Douglas Wilson, study co-author from the University of California, Santa Barbara, told LiveScience “This process covers 60 percent of the Earth’s surface, and it’s an ongoing process that has replaced all of the seafloor since 180 million years ago. In terms of understanding the planet, it’s a fundamental process."

Bryan Kennedy, of the Science Buzz team, got to go on a research cruise on the JOIDES Resolution. While he was aboard, we featured him as a Scientist on the Spot.

Also, we have a running feature on the work done on the JOIDES Resolution. Pretty cool!
