How Geophysical Surveys can meet your Needs

Archaeologists can use geophysical surveys as a non-invasive technique to identify buried archaeological resources prior to or without excavation. Buried materials or features often produce a slight different magnetic field than the local magnetic field around them. A gradiometer is a geophysical survey tool that measures these local magnetic fields and anomalies. This technique not only saves time and money, it also helps preserve our important cultural resources for the future.

Examples of Gradiometer Applications

Prehistoric Camp Sites

Prehistoric Villages

Prehistoric Earthworks and Mounds

Historic Graves and Cemeteries

Historic Farmsteads

Other Historic Settings

About our System

The Sanford Museum uses the FM256 fluxgate gradiometer in combination with Geoplot software, ArcGIS, total station, and GPS mapping equipment in order to create three-dimensional maps. These maps can demonstrate potential feature locations, densities, and landscape of archaeological sites without ever breaking ground. The data collected with these instruments will be in digital format, leading to fast, efficient and accurate information.

Experience

Megan Stroh is the staff archaeologist and experienced geophysical surveyor. She has a Master of Science Degree in Cultural Resource Management from St. Cloud State University and has worked on both prehistoric and historic settings.
