Objective Study of the accretion system in the northern part of the North Fiji basin: Pandora Ridge, Tripartite Ridge and Rotuma Ridge. The axes of accretion in the back-arc basins are characterized by complex geometry, indicating instability over time and space. This is the case in the north-south central system of the North Fiji basin. The NOFI project mapped and sampled the East-West ridge, to the north of the central North-South system, which had appeared, on the basis of previous patchy data to be a complex, highly segmented axis, showing significant discontinuity. The project includes a mapping phase with full coverage (South Pandora Ridge box) and surveying of the Tripartite axis with limited boxes.
