In December 2001 a geophysical survey was conducted to search for remains of Fort Louis. Three methods–earth conductivity, magnetometry, and thermal imaging–were conducted in a 5.7 acre target area (1).
In 2004, NCPTT supported the Friends of Mobile with funding to enable the application of two additional geophysical survey methods: electrical resistance and ground penetrating radar. A goal of the project was comparing the applicability of all five remote sensing methods through ground truthing test excavations (1).
