Abstract:
Track line geophysical data were 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 total magnetic field was measured using a proton precession magnetometer towed behind the ship.

| Mado_maganom.grd | application/x-netcdf | 56.6 kBytes | 0.014803deg | Gridded magnetic anomaly. Total magnetic field data obtained in each cruise was cleaned, and subtracted IGRF-13. The data downloaded from NGDC Marine Trackline Geophysics Database were combined. The dc-shift smaller than 11 nT was applied to minimize the cross-over errors among surveys. Grid interval is 1500m.
