9/11 TECH TOOL USED IN SEARCH FOR ANGOLAHigh tech equipment used to assess underground damage near the World Trade Center site after 9/11 will now assist archaeologists in the search for artifacts of an 1800’s slave settlement near Tampa Bay known as Angola. Using a method called Radar Tomography (RT), St. Petersburg-based Witten Technologies will scan a 2 acre site at Manatee Mineral Springs in hopes of finding remains of the place that served as a haven of freedom for escaped slaves, free blacks and Seminoles.

“We’re excited about RT’s archaeological potential. Similar to our work with the utility industry, we can precisely identify where objects of interest are and provide targets during exploratory digging,” said Robert Green, Witten’s Chief Executive Officer. According to Green, the company is volunteering their services in the search for Angola.

Without turning a shovel, Green says underground items such as house foundations, artifact clusters and archaeological features can be identified using geophysics. The non-invasive method involves a mobile array of ground-penetrating radar antennas, a laser survey station, and image processing software. Initially, the technology was developed to provide a 3D map of existing underground infrastructure to companies prior to major road or utility construction projects.

Witten provided RT services in lower Manhattan during recovery and rebuilding efforts after 9/11.

“The value of contributions from Witten and the Corps to our project is tremendous. RT scanning of Manatee Mineral Spring will provide a rich source of information for us,” said Dr. Uzi Baram, Angola scholar and Associate Professor of Anthropology at New College of Florida. Reflections of Manatee Director Trudy Williams adds, “Our goal is to safeguard potential archaeological evidence for research such as this.” In addition to Angola layers, Baram hopes RT will locate materials that reveal the multiple histories of the spring.
