What is recorded here?
The1959 report explains how echo-sounding profiles were organized into a North Atlantic physiographic diagram and provinces, with detailed ridge and axial-valley descriptions. Scattered ship tracks became an interpretable view of a largely inaccessible landscape. The authors distinguish recorded profiles from inferred relief between tracks, state the map's resolution and identify both striking morphology and unresolved geological interpretation.

Scientific scope
The target is the selected physical mapping/morphology contribution in the 1959 report, whose first sheet covers 17–50 degrees north; it is not a complete world-ocean map or every earlier chart. Between-track relief is interpolated/extrapolated and explicitly speculative.40:1 exaggerated profiles and small map scale limit what features are represented; positional/data-quality limits remain. Plate 1 and the figures were not visually audited, and no raw sounding reconstruction was run. Ridge origin remains unresolved in the inspected text; this is not a complete plate-tectonics proof. The three source bylines do not absorb the named expedition, navigation, plotting and recorder-development teams, nor later maps or theories. No life-science observations are curated by this target.
