Figure 9

Comparison of the total magnetic intensity 1-min values at the Kakioka Observatory (KAK) and leveling corrections. An approximate value of 46,000 nT is subtracted from the 1-min values, and the subtracted values (black) are compared with leveling corrections along the track lines of the 84002111 and 84002112 cruise/legs of the R/V Jean Charcot. Good correlation was obtained particularly between the 1-min values and the corrections calculated by Equation 11a (red curve).
