Magnetic processed data (Proton precession magnetometer working area dataset) of RV HAKUHO MARU during cruise KH-18-02, trackline magnetic anomaly

Track line geophysical data were collected in the Mado Megamullion oceanic core complex and the adjacent areas. The data were obtained in 2020 during cruise KH-18-02, with R/V Hakuho-maru (JAMSTEC) 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.
