Magnetic processed data (Proton precession magnetometer working area dataset) of RV YOKOSUKA & RV HAKUHO MARU during cruise YK18-07, YK19-04S, YK20-18S & KH-18-02, gridded magnetic anomaly@en

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.
