We use the GEBCO global bathymetric product alongside other data sets, including magnetic anomaly and vertical gravity gradient, to interpret the seabed geomorphology of approximately 24.7 million km2 of the southwestern Pacific Plate at an effective scale of 1:3,000,000. Manual interpretation was performed to accurately define abyssal plain basins, plateaus, troughs, faults, tectonic and volcanic rises, volcanic chains and other geomorphic units. The resulting description of these units and their geographical disposition, placed in the context of current scientific literature, contributes to our understanding of seabed composition and formational history. Other potential applications of this work include its use as a surrogate for regional habitat-type classification in environmental management, support for seabed minerals exploration, and as a constraint in mineral resource estimation.
