G_1_16 — Ground-Penetrating Radar in Archaeological Prospection
Ground-Penetrating Radar (GPR) is a non-invasive geophysical survey technique that transmits short pulses of electromagnetic (radar) energy into the ground and records the reflections returned from subsurface interfaces
G_1_17 — Experimental Replication of Ancient Technologies
Experimental replication — the systematic recreation of ancient objects, structures, and processes using materials, tools, and techniques available in the past — is a core methodology in experimental archaeology, enablin
G_1_01 — Experimental Archaeology: Testing Ancient Technologies
Experimental archaeology is a sub-discipline that tests hypotheses about past technologies, construction methods, and subsistence strategies through physical replication and controlled experimentation. From Thor Heyerdah
