Micronesian scientist becomes first Pacific Islander to reach ocean's deepest point

Nicole Yamase visited the Challenger Deep trench, which lies nearly 11km below the surface

It is a place that has been visited by fewer people than have flown to the moon - pitch black, 11km down, the last frontier.

Last month, Nicole Yamase became the first Pacific Islander, the third woman, and, at 29, the second-youngest person to visit Challenger Deep, the deepest known part of the Mariana Trench.
