New South Associates (NSA) utilizes state-of-the-art geophysical methods in archaeological surveys.


NSA was an early adopter of geophysical methods in archaeology and has conducted innovative studies on how they can be used in archaeological settings. NSA uses ground-penetrating radar (GPR), magnetic gradiometer, resistivity, electromagnetic conductivity, and metal detecting. Each method relies on different geophysical principles and is used to resolve different types of features on different types of sites. NSA has multiple instruments and highly trained staff to provide these services to its clients.
