Description: GEBCO 2019 bathymetry of the Challenger Deep and the Sirena Deep. (a) Mariana Trench multibeam bathymetry data gridded at 75 m acquired on‐board the DSSV Pressure Drop overtop the GEBCO 2019 source grid (as shown in Figure 1) and the complete GEBCO 2019 grid with hillshade. EM 124 black contours at 500 m intervals, GEBCO 2019 grey contours at 1,000 m intervals. The white circle indicates the deepest point and submersible dive location, the white triangle indicates the submersible dive location from Sirena Deep, the red spot was the deepest point derived by van Haren et al., (2017). (b) Challenger Deep. (c) Sirena Deep. Bathymetric cross sections A’–A” and B’–B” over Challenger Deep and Sirena Deep displayed in (d) and (e), respectively.
