This looks like it was in the trench.

http://en.wikipedia.org/wiki/Mariana_Trench
The Mariana Trench is the deepest part of the world's oceans, and the lowest elevation of the surface of the Earth's crust. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2,550 kilometres (1,580 mi) long but has a mean width of only 69 kilometres (43 mi). It reaches a maximum-known depth of about 10.91 kilometres (6.78 mi) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end,[1] although some unrepeated measurements place the deepest portion at 11.03 kilometres (6.85 mi).[2] If Mount Everest, the highest mountain on Earth at 8,848 metres (29,029 ft), was set in the deepest part of the Mariana Trench, there would be 2,076 metres (6,811 ft) of water left above it.[3]

Like other oceanic trenches, the Mariana Trench has been proposed as a site for nuclear waste disposal,[10][11] in the hope that tectonic plate subduction occurring at the site might eventually push the nuclear waste deep into the Earth's mantle. However, ocean dumping of nuclear waste is prohibited by international law.[12][10][11] Furthermore, plate subduction zones are associated with very large megathrust earthquakes of which the effects on any specific site are unpredictable and possibly adverse to the safety of long-term disposal.[11]
