Figure 5.2 Magnetic close-plot survey in Kyrenia showing the metal detector survey super- imposed on the contour plan. Shaded areas indicate metal detector targets. Z1 and Z4 corre- spond to magnetic anomalies whereas other metal detector targets do not correspond to magnetic targets. This indicates nonferrous targets. Subsequent excavation showed these targets were lead sheathing.
Figure 5.3 Magnetic close-plot survey Amsterdam wreck site, Hastings, UK. This detailed magnetic survey shows a number of interesting anomalies. The very strong linear feature running from upper left to the bow of the vessel was an iron water pipe. The large isolated anomaly, lower right, is a very large iron object, possibly a cannon or anchor. The faint linear feature running from the bow of the vessel to the lower left is possibly a mast. The large iron concentration in the center of the vessel is likely to be an iron shot locker.
