Abstract:
Multibeam bathymetry was collected in the Mado Megamullion oceanic core complex and the adjacent areas. The data were obtained between 2018 to 2021 during five cruises; R/V Yokosuka (JAMSTEC) YK18-07, YK19-04S, YK20-18S, YK22-18S, and R/V Hakuho-maru KH-18-02. The survey covers the oceanic core complex and the adjacent area from 138°20'E to 139°40'E and from 22°50'N to 24°50'N. The bathymetry was collected by EM122 (12kHz) and SeaBeam2020 (20kHz).

JTOPO is a quality-controlled bathymetry grid (30"") based on the previous surveys by Japan Coast Guard. The original soundings were acquired by old/new multibeam sonars and very old single-beam sonars.
