2-16-05 Ground Penetrating Radar Survey Written by Todd Bowers (5-7-05) Last update (5-7-05) Introduction      This was a pilimary survey to see if we could image bones in a lithfiled sediment and surounded by tin foil using GPR. Survey Data NOTE THAT ALL DATA WAS RECORDED IN CONTINOUS MODE AND DIDN'T HAVE A SET STEP Data File Name Data Description 21605.DT1 21605.HD 21605wiggle.jpg      This was a survey with no sample located below the the plywood platform. This was done in order to see was the surounding environment affected the data. Only traces collect after trace 40 or so are any good DINO1.DT1 DINO1.HD DINO1wiggle.jpg      This was a quick survey over the femur DINO2.DT1 DINO2.HD DINO2wiggle.jpg      Survey run from the platform using 1/4 inch plywood over femur sample DINO3.DT1 DINO3.HD DINO3wiggle.jpg      Kenny Bader gently moved the GPR directory over the sample without touching the sample. The survey was run rather quickly and does not contain many traces. It was also impossible to hold the GPR directly onto the sample or keep the gpr pointed strainght up and down. DINO4.DT1 DINO4.HD DINO4wiggle.jpg      Survey over tail sample in which plywood was used. DINO5.DT1 DINO5.HD DINO5wiggle.jpg      Perpendicular to sample. DINO6.DT1 DINO6.HD DINO5wiggle.jpg      Parallel to tail sample. DINO7.DT1 DINO7.HD DINO7wiggle.jpg      The gpr was not moved in this survey. The gpr was put directly onto (touching) the tail sample. DINO8.DT1 DINO8.HD DINO8wiggle.jpg      Quick survey of "big foot" bone buried in sand. Runs parallel to sample. DINO9.DT1 DINO9.HD DINO8wiggle.jpg      Quick survey of "big foot" bone buried in sand Run perpendicular to sample. Compare this to the sample in the 2-19-05 survey in which foil was used
