A little more perspective
301 unchanged 75-meter raster cell centers along a 22.5-kilometer section. Depth is negative raster elevation. No interpolation, missing-cell filling, datum transformation or vertical exaggeration. Straight segments connect measured cells; they are not additional soundings. The section reaches 5555.36865234375 meters at 79.140915°, 2.783116°. Stored decimals preserve the raster value, not centimeter accuracy. Both ends remain underwater.
The Five Deeps study reports 5,551 ± 14 meters for Molloy Hole. This archived grid has a slightly different deepest cell, retained without adjustment. The published analysis and this archived grid are separate results. Neither the profile nor its vertical datum has been adjusted to force agreement. The acquisition report identifies EGM96 as its geoid reference.
Molloy Hole is a deep basin in Fram Strait between Greenland and Svalbard. It is an Arctic depth reference rather than a subduction trench like Mariana or Tonga. The west-to-east section spans 22.5 kilometers, with no vertical exaggeration.
