SYNONYMS OR RELATED TERMS: geophysical survey CATEGORY: technique DEFINITION: The location and recording of buried sites by detecting variations in the magnetic properties or resistance to an electrical current of the soil. Many archaeologicalsurveying techniques designed to identify features without excavationuse instruments that measure physical properties of surface materials.
CATEGORY: term DEFINITION: A site where stone was tested for suitability, whether the stone was used or not.
CATEGORY: technique DEFINITION: A remote sensing method used in aerial reconnaissance and based on weak variations in temperature which can be found above buried structures whose thermal properties are different from those of their surroundings.
SYNONYMS OR RELATED TERMS: electromagnetic prospecting CATEGORY: technique DEFINITION: A geophysical surveying method used to locate archaeological features and differences in sediment or soil textures. A pulsed induction meter or soil conductivity meter generate electromagnetic waves at the surface of the earth, penetrating it and inducing currents in conducting ore bodies, thereby generating new waves that are detected by instruments at the surface or by a receiving coil lowered into a borehole. This technique only works at a very shallow level, and no electromagnetic instrument is as accurate as the resistivity meter or a proton magnetometer.
Emery, Walter Bryan (1903-1971)
CATEGORY: person DEFINITION: British Egyptologist noted for his careful surveying and study of prospective sites. He discovered galleries of the Bucheum in Armant, burials of Nubian X-Group kings, queens and nobility of 4th-6th century AD, and at Saqqara, excavating many Archaic Period mastabas. His most important discovery was a row of 1st-Dynasty tombs attributable to kings or nobles. He excavated at Thebes-West Bank, Nubia's Buhen and Ballana and Qustul.
SYNONYMS OR RELATED TERMS: IRLS CATEGORY: technique DEFINITION: Imagery that results from equipment that scans from horizon to horizon to detect and record actual temperature differences (thermal prospection) on continuous videotape.
CATEGORY: technique DEFINITION: The nondestructive techniques used in geophysical prospecting and to generate archaeological data without excavation. It is a general term for reconnaissance and surface survey techniques that leave subsurface archaeological deposits undisturbed. Reconnaissance and site survey methods use such devices as aerial photography and pedestrian survey to detect subsurface features and sites. It includes the detection of hidden archaeological features such as walls, pits, or roads by means of sound or radar impulses passed through the ground.
SYNONYMS OR RELATED TERMS: thermal prospection CATEGORY: technique DEFINITION: Non-photographic technique which uses thermal or heat sensors from aircraft to record the temperature of the soil surface. Temperatures can be mapped using thermography to provide a graphic or visual representation of the temperature conditions on the surface of an object or land area. Variations in soil temperature can be the result of the presence of buried structures.
