  Information - GI11 Geophysical monitoring of near-surface: past, present and future (co-listed in G & GM)

Event Information
This session discusses instrumentation and methods, as well as data analysis algorithms used in the survey of the uppermost layer of the terrestrial surface to pursue archeological studies. This includes
a) the development and exploitation of innovative measurement instrumentation and techniques able to exploit diversity in sources and the observation and to achieve robust raw data; b) the development of advanced processing techniques based on refined models of the geophysical, electrostatic, magneto-static, electromagnetic phenomenon and on inversion schemes able to obtain reliable and stable solution of the problems also in applicative cases; and c) the development and feasibility study of techniques, based on combined deterministic/probabilistic/statistic principles, able to perform an integration of the different measurements/reconstruction techniques with the aim of giving the most complete, reliable and detailed, multi-(time and spatial) scale, multi-resolution knowledge of the scenario.

All human activity (initial learning, infrastructure development, buildings and roads construction, transport communications, sport and recreation, etc.) and human health is associated with the earth’s near-surface structure. Drilling holes into the ground cannot economically provide the necessary information about the searched archeological infrastructures. Therefore, noninvasive geophysical monitoring of near-surface is especially significant. From uncoordinated observations of the past geophysicists have switched over to the present system of continuous 3-D measurements. Thus, the future geophysical monitoring will be based on the fusion of observations of geophysical field parameters performed at different spatial, time and resolution levels (underground sensors, surface measurements, remote pilot vehicle and satellite surveys). In particular, this is true for the near-surface monitoring where a large number of geophysical methods may be applied (besides the several methods specially developed for studying Earth’s deep structure).
