Keros Island Survey 2012-2013: Season 2012
Survey: Geophysical survey
The island was divided into 1584 one-hectare tracts, each subdivided into five 20 m segments. 764 tracts were walked, 38,350 sherds and 2,800 obsidian fragments counted, and 2,246 sherds and 277 special finds collected. An intensive sampling methodology adopted at two areas of interest (or Polygons 1 centred on modern Konakia and 2 further west on the north coast) involved complete collection in 5 m2 circles, with diagnostic ceramics and other special finds collected in 100 m2 squares. Geological and geomorphological study focused on the creation of a new geological map and cross-sections of the island, and the recording of geomorphological features, soil types and land-use practices. Single column profiles from exposed sections were cleaned, and the stratigraphic units described and sampled for grain size, organic carbon and calcium carbonate content to investigate depositional history and soil formation processes. C14 samples were taken where cultural material was noted. Specific exposed profiles were sampled for soil micromorphology and OSL dating. Geomorphic maps are being constructed for areas of archaeological investigation. The extensive terracing systems were also investigated: exposed profiles were recorded and sampled for sedimentological analysis and dating. Coring was conducted in specific terrace infills and foundations.
