Fig. 2 — APEI scenarios were anchored by important areas identified by expert opinion before scenario development began. Important areas include (A) critical transform faults (that is, Vema and Romanche), biogeographic transition zones (that is, the bathyal transition zone in the region of the RTF), and genetic hybrid zones (that is, Broken Spur). Three APEI network scenarios were developed for the nMAR subunit, with core lengths along the ridge axis of (B) 100 km, (C) 200 km, and (D) 300 km; each APEI also has a 50-km buffer on the northern and southern sides of the core zone.
