Digitizations of seesaw propagating ridges

Digitizations of mid-ocean ridge features in support of "Ridge propagation and the stability of small mid-ocean ridge offsets" by Harper et al., (in prep). Vertical-Gravity-Gradient.kmz is a Google Earth network link to a global vertical gravity gradient image overlay. This was used to identify and digitize features. Digitizations.kmz contains the polyline digitizations of: off-axis traces of seesaw propagators (SSPs); ridge segments and offsets associated with active SSPs; and ridge segments and offsets associated with transform fault offsets (in the same regions as SSPs).
