On the JOIDES Resolution: Turbidite Transport (+ video)

On this expedition, we’re studying sediments that have been eroded from the Himalayas, the highest mountain range in the world. The Ganges and Brahmaputra rivers carry this sediment to the delta in Bangladesh, but what happens next? How does this material get all the way out to the middle of the Bay of Bengal where we’re drilling, almost 2,000 kilometers (1,243 miles) away?

We’ll be devoting almost three weeks of our eight-week International Ocean Discovery Program expedition to drilling at this site. Our target: to reach 1,500 meters (about a mile) depth. Drilling this deep is a major challenge when you are drilling into the seafloor, which just so happens to be more than 3,600 meters (about two miles) below sea level.

But why so deep? And why here?
