The study concludes according to their calculations the deepest observed seafloor depth was 10,935 m (35,876 ft) ±6 m (20 ft) below mean sea level at a 95% condidence level at 11°22.3′N 142°35.3′E﻿ / ﻿11.3717°N 142.5883°E﻿ / 11.3717; 142.5883 in the eastern basin. For this estimate, the error term is dominated by the uncertainty of the employed pressure sensor, but Greenaway et al. show that the gravity correction is also substantial. The Greenaway et al. study compares its results with other recent acoustic and pressure-based measurements for the Challenger Deep and concluds the deepest depth in the western basin is very nearly as deep as the eastern basin.
