Type of survey: Proton magnetometry; Instrument: 2 Geometrics 856A (base & roving units); Prospection depth: up to 1.5 m; Sampling interval: 1 x 1m; Area surveyed: 7200 sq. m; Date of survey: 6/96.
Comments: The area surveyed is in a level field
immediately to the north of the excavated portion of the Roman
city (left). A base station recorded diurnal changes in the
background magnetic field every 30 seconds (second figure). The
diurnally corrected data from the roving unit clearly shows the
layout of the Roman street grid (third figure). Many rooms in
adjoining areas are indicated as well as a large courtyard.
There is a large burned zone near the top center; the arcing
washed out area to the right is due to a large
iron water tank nearby. The line of bright spots about one-third
of the image length from the left are most likely cisterns cut
into a sloping escarpment that is also indicated. The city plan
shown here corresponds well with the excavated results
immediately to the south of this area (right figure).
Type of survey: Ground penetrating radar; Instrument: Geophysical Survey Systems, Inc, SIR-System 3; Antenna frequency: 300MHz; Prospection depth: 3-4 m; Sampling interval: 1 m transects; Area surveyed: about 60 x 40 m; Date of survey: 6/96.
Comments: These 20 m profiles clearly show two walls and a
floor about 1.5-2 m below the surface. The three stacked
profiles (left) are each separated by one meter. The walls are
either Greek or Roman. They were discovered under the parking lot
of this national archaeological park, about 30 m to the south of
the principal gateway to the Greek settlement. The right transect
is one of about 100 obtained at this site.
