Objective

The SUDACORES cruise will explain how the ridge morphology has evolved and its magma supply over the past 10 million years: 1) in connection with the influence of the Azores hotspot in the Menez Gwen-FAMOUS region and 2) in connection with the stages of the OH1 segment's development in the region located south of the Oceanograph fracture zone.
