The Eiffel Tower (/ËaÉªfÉl ËtaÊÉr/ EYE-fÉl TOWR; French: Tour Eiffel, pronounced: [tuÊâ¿ÉfÉl] listen) is a wrought iron lattice tower on the Champ de Mars in Paris, France. It is named after the engineer Gustave Eiffel, whose company designed and built the tower.
A remote sensing technique that monitors the electrical resistance of soils in a restricted volume near the surface of an archaeological site; buried walls or features can be detected by changes in the amount of resistance registered by the resistivity meter.
At Isthmia, the surface elevation is measured at five different points of the trench prior to excavation, ensuring that the slope of the ground can be reconstructed later. Excavation itself proceeds slowly. Soil is removed with pick, shovel, and especially trowel, the hallmark tool of the archaeologist.
