Geophysics results 9th April 2011 (part 2)

I have already described the very useful geophysics training session held last Saturday, 9th April.  That post included the preliminary results from the survey work carried out in the morning, when a problem occurred half way across the grid square (ref D21).  A few very committed members decided to re-survey the grid square after lunch.

Mark managed to download the raw data onto the AVAS laptop, and emailed it across.  After a bit of editing to remove a few rogue readings, I managed to run the software to convert the data and produce a preliminary plot.  The result is shown below:

What is promising is that the relative pattern of high and low readings matches that from the first attempt at surveying the grid square, despite re-calibrating the starting threshold prior to beginning the second run.  We will need to survey some adjacent squares before attempting any sort of interpretation.  Mark and Bill are planning some more survey work soon ;-), so watch this blog!
