This navigational system is so accurate that it can return to an underwater site that was identified last summer to within a few meters. When the RV Seminole reaches a survey area, a marker buoy is deployed over the starboard side of the vessel. After anchoring, our divers gear up and move out. Divers make a standard giant stride entry off the stern of the boat and await for permission from the safety diver before descending. The exposed limestone may indicate an area where Paleoindians quarried chert for stone tools.
Divers have better chances of finding prehistoric material in and around areas with high relief.
Note these artifacts that have been found by Brian early in the project. Once the divers have identified the highest limestone relief in the area, they measure out in the four cardinal directions. This gives an idea as to the size of an area. The divers then return to the Seminole and report their findings. If divers locate 10 or more artifacts in a given area, it is given Florida Master Site File designation.
