Cultural Surveys Hawai‘i has in-house equipment and trained personnel to provide ground penetrating radar services throughout the State of Hawai‘i. This technology is increasingly used to detect anomalies in sensitive areas before more intrusive methods are implemented. In addition CSH has had GPR training and software from GPR specialist Lawrence B. Conyers author of “Ground-Penetrating Radar for Archaeology”.

Geophysical Survey Systems (GSSI) — Model: SIR-3000 with 400 MHz antenna In 2008 CSH purchased GPR equipment and professionally trained two archaeologists. The use of GPR allows gathering of survey information using non-invasive methods which contributes to the creation of archaeological inventory survey site testing strategies, conservation, and preservation through avoidance.

The usefulness and adaptability of this technology is increasing as it is applied to more and more field situations involving many types of ground surfaces as well as geologic and soil conditions.
