Comments
The mostly square fish sauce basins are clearly recognizable over large parts of the entire complex. The finding of the quay wall, which was initially only presumed, was confirmed as part of a very well-preserved port facility in a later excavation campaign in which also several fish sauce basins were uncovered.

This earth resistance survey was performed on dry, sandy soil with plenty of bushy vegetation. Due to the extremely loose soil area below the bushes, a lack of coupling led to particularly frequent incorrect measurements. Despite these poor measurement conditions, a 3x3 median filtering was able to achieve a very good result.
