A little more perspective
401 unchanged 75-meter raster cell centers along a 30-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 8266.2578125 meters at -55.230360°, -26.173555°. Stored decimals preserve the raster value, not centimeter accuracy. Both ends remain underwater.
The Five Deeps study reports 8,265 ± 13 meters at Meteor Deep, the deepest site in the South Sandwich Trench in that survey. 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.
Meteor Deep lies near 55.23° S. Despite the trench extending toward Antarctica, this site is in the Atlantic under the study’s 60° S ocean boundary. Compare it with Factorian Deep to see why the deepest point in a trench need not be the deepest point in the neighboring ocean.
