Talk:Mariana Trench

Lead and adjacent footnote disagree on Challenger Deep's depth (10,984 vs 10,994 m)

The lead, citing Gardner et al. (2014), says: "The maximum known depth is Template:Convert at the southern end of a small slot-shaped valley in its floor known as the Challenger Deep." But the very next sentence's footnote (comparing with Everest) flatly states: "Mariana Trench is Template:Cvt deep," cited to a different source.

Two different "the depth" figures appear within a few words of each other. The 10-m gap is technically inside Gardner et al.'s ±25 m uncertainty, but the article isn't presenting these as one measurement with uncertainty — it's presenting two different point figures in two different places. The body should pick one survey result (probably 10,984 ± 25 m, the more recent multibeam figure) and either drop the 10,994 m number or annotate it as an earlier survey ("the older figure of 10,994 m, often quoted, is consistent with this within the uncertainty").
