INTRODUCTION 

Auxiliary material includes a table reporting the location of each ridge segment 
discussed in the manuscript and their characteristics, compiled from literature, 
Table S1; the list of references used too build this table but not 
appearing in the main text, Text S1; and a world map on which each 
ridge segment location is reported, Figure S1.

Location and characteristics of mid-ocean ridge segments appearing in Figure 2. 
1.1 Column "Ridge", name of the entire ridge to which this segment belongs 
1.2 Column "Lon", degree E, Longitude of reference point for this segment 
1.3 Column "Lat", degree N, Latitude of reference point for this segment 
1.4 Column "VP", mm/yr, spreading half rate between the two plates  at this 
point. An asterisk means that the spreading rate was calculated using W. Menke's 
Spreading Rate calculator, accessible online at 
http://www.ldeo.columbia.edu/users/menke/plates.html. Otherwise, spreading rate 
from reference in last colum. 
1.5 Column "Gamma", degrees, obliquity angle measured between the plate 
spreading direction and the direction normal to the ridge 
1.6 Column "VE", mm/yr, Ve defined in text as the plate seperation half-rate 
(column 1.3) multiplied by the cosine of the obliquity angle (column 1.4) 
1.7 Column "Morph", Ridge morphology classification as U (ultraslow), T 
(transitional), S (slow), or ? unknown 
1.8 Column "Reference", paper in which the data used to determine the morphology 
of each ridge segment was published. The full reference is either in the main 
text or in the auxiliary text

Location map for the mid-ocean ridge segments reported 
Figure 2 of the main text and in the Auxiliary Materials in Table S1. Segments with obliquity less than 15¡ are marked with a diamond, those with obliquity higher than 15¡ are marked with a star. The color correspond to 
slow (white), transitional (orange), and ultraslow (red) morphology
