Analysis x (bow) and z (downward) components of observed magnetic anomaly along the 6K#918 track. From top to bottom: observed (red line) and synthetic (blue line) magnetic anomaly intensity, magnetization, phase, vehicle altitude, and seafloor/vehicle geometry. Black and gray circles are those with high coherency of > 0.5 and from 0.3 to 0.5 on both the x and z components, respectively. The location of the Kairei hydrothermal field and collected basaltic rock samples are shown in the bottom figure. Major element composition for lava samples of 918R02, 918R02, and 918R10 is shown in Additional file 5: Table S1
