Having established that GPR surveys were most effective during the drier summer months, and that soil moisture appeared to have little effect on the magnetometry survey, the 2011 field season consisted of a considerably more extensive survey coverage. Ithaca College’s purchase of two new Måla GPR systems and 500 MHz antennae, and an additional Geometric G-858 cesium-vapor magnetometer, made it possible to run two survey teams at once. During 5 weeks in June and July of 2011, we expanded the survey to cover areas north of Building X and south of the highway at KAD, and between the excavations at Vournes and Tsaroukkas at Maroni. In addition to attempting to determine the extent of the settlements, we sought to investigate the urban organization of each site.
At KAD results were ultimately inconclusive with the new GPRs. While the 2008 and 2010 surveys had showed promise with the GSSI 400 MHz antennae, the Måla 500 MHz antennae may not have propagated signals that effectively penetrated the ground surface. Magnetics data was again noisy and even after processing did not appear to be effective.
At Maroni, however, both GPR and magnetic surveys imaged an intriguing c. 300 m2 rectilinear feature in units 32, 33, 44 and 45, less than 200 m from the complex of buildings at Maroni-Vournes. These data support an argument that Maroni was an urban complex with low-density settlement areas from at least Vournes to the coast at Tsaroukkas.
