Fig. Eight typical profiles of the mid-oceanic ridge in the North Atlantic, South Atlantic, Indian and South Pacific Oceans. The smooth relief across the crest of the mid-oceanic ridge in the South Pacific contrasts markedly with the rougher topo- graphy of the other oceans. Profile 2 was obtained aboard Crawford and Profile 8 was obtamed aboard Horizon. The remaining profiles were obtained with a Precision Depth Recorder aboard Vema.

(Vertical exaggeration of profiles is 100:1.) Fig. 14 (Ewing, Ewing and Talwani, 1963) shows a ridge profile in the North Atlantic, between Dakar and Halifax, based on seismic-refraction (Ewing and Ewing, 1959) and reflection measurements. The unconsolidated sediments, whose thickness was measured continuously.
