Archeological Investigations

Our integrated geophysical investigations include several high-profile archeological projects, including work at the Statue of Liberty Island National Monument, Bunker Hill Monument, Lexington Battle Green, Secaucus Potters’ Field, and for the History Channel’s search for Blackbeard’s alleged treasure hoard on Lunging Island in the Isles of Shoals.

Geophysical methods offer archeological investigations a major advantage: the ability to detect features of possible historical interest without disturbing the subsurface.
