SHG’s geological and geophysical survey services provide value to your project, either alone or as a key component of an integrated site characterisation effort to gain insight into ground conditions. Prior to geophysical survey the test locales were cleared of agricultural crops as needed, and the surface was prepared (i.e., plowed, disked). Geophysical surveying provides a non-destructive and cost effective method to locate and determine subsurface features and conditions. Geophysical surveys are considered an efficient, cost-effective process for identifying potential sub-surface archaeology without the use of invasive methods such as test trenching or excavation. Next, a datum was established and the test locale was gridded into 20 m × 20 m (66 ft × 66 ft) sampling units. In archaeology, survey or field survey is a type of field research by which archaeologists (often landscape archaeologists) search for archaeological sites and collect information about the location, distribution and organization of past human cultures across a large area (e.g. Parallel Seismic Survey Methods Tests and Instruments; GPR Cost, Applications, Acquisition, and Interpretation; How to Find Underground Storage Tanks With Geophysics; Shallow Bedrock Surveys for Agriculture ; Sub-bottom Profiler Survey, Interpretation, and Theory.
