HMS Challenger sounds the deep that will bear her name

1. Story
2. During the Challenger expedition, a wire sounding in the southern Mariana Trench recorded a depth far greater than anything then known, and the feature was later named the Challenger Deep after the ship. The measurement was made by lowering a weighted line - a method with large and poorly-quantified errors compared with modern acoustics - which is where the long history of disagreement over this one number begins.

31. Evidence
32. Post-2000 published maximum depths for the Challenger Deep, and the geodetic positions assigned to them, disagree by more than the accompanying stated uncertainties. A 2010 multibeam survey recorded a deepest sounding of 10,984 +/- 25 m, a value not confirmed by any direct pressure-gauge descent.
