Dirty work

Haitham Aljahdali, of King Abdullah University of Science and Technology, or KAUST (left) and Alaa Albarakati (center) of King Abdulazziz University, both in Saudi Arabia, get their hands, and everything else, dirty while preparing to cut a gravity core. The core was taken from sediment under brine pools, an unusual feature of the Red Sea, during an October 2008 cruise led by WHOI scientist Amy Bower and funded by KAUST.
