Figure 6From: A new leveling method without the direct use of crossover data and its application in marine magnetic surveys: weighted spatial averaging and temporal filtering Comparison of the total magnetic intensity hourly values at the Cape Wellen Observatory (CWE) and leveling corrections. Variations of leveling corrections along the track lines of the NORTSD68 (red) and OPR483 (green) cruises closely follow the hourly values (black). An approximate value of 55,400 nT is subtracted from the hourly values. The location of the CWE is shown in Figure 4.Back to article page
