Another great day of geophysics! We had two really interesting lectures in the morning. First, Jarrod Burks gave a talk about magnetometry. He manages to make a complicated subject really accessible. Then David Wilbourn introduced us to his software package TerraSurveyor®, which is used to process the data. It was fascinating to look at the raw data, then see what a difference a few software processes made to the final product.
Then, off to the field. We’ve moved out into a bigger field, where the Foerster® magnetometer was put to work surveying forty meter grids, folks were learning the fine points of using the Bartington® magnetometer, and two GPR machines were covering lots of ground. Meanwhile, up on the hill was more resistivity and magnetic susceptibility. One of the best things about this course is the opportunity to try lots of different equipment.
We’ve gotten some images from yesterday’s flight of the UCL Qatar drone. Here is a great view of the new “Olympic 2012” volleyball courts. And, as a bonus, an image from Bill Martin’s resistivity survey, showing the Roman road. Notice where the stones were robbed out for use in some later building project.
