The CTD measured pressure at 10,928 m (35,853 ft) of seawater depth was 1,126.79 bar (112.679 MPa; 16,342.7 psi).[28][29] Due to a technical problem the (unmanned) ultra-deep-sea lander Skaff used by the Five Deeps Expedition stayed on the bottom for two and half days before it was salvaged by the Limiting Factor (crew: Patrick Lahey, Pilot; Jonathan Struwe, DNV GL Specialist) from an estimated depth of 10,927 m (35,850 ft).[30][29] The gathered data was published with the caveat that it was subject to further analysis and could possibly be revised in the future. The data will be donated to the GEBCO Seabed 2030 initiative.[31][27][32][33][34] Later in 2019, following a review of bathymetric data, and multiple sensor recordings taken by the DSV Limiting Factor and the ultra-deep-sea landers Closp, Flere and Skaff, the Five Deeps Expedition revised the maximum depth to 10,925 m (35,843 ft) ±4 m (13 ft).[35]
