Although this isn’t CAGG related, or Hertfordshire, I thought members of the group might be interested in my latest geophysical adventures.
Some 15 years ago I undertook a survey in Alba Iulia, Romania, for a colleague. The site was part of one of the Roman cities at Apulum which grew-up alongside the legionary fortress. The results were pretty good, but I was only taking one reading per square meter. Since getting the RM85 I have been wanting to return and re-do the survey at higher resolution. Well, be careful what you wish for! Last Saturday, I found myself on the way…
Yes, you did read the time correctly. I flew to Cluj-Napoca via Munich. Sadly, when I got to Cluj, my luggage was still in Munich. Thankfully, they delivered it all safe-and-sound the next day but it did mean I lost a half day of survey.
Alba Iulia has changed quite a bit in the fifteen years. The citadel, especially, has been restored beautifully and now has a series of bronze statues decorating the area.
Having lost half a day, we got started in the afternoon. Three whole grids and partial that day, seven whole grids a four partials (including one very silly small one) the next day, and eleven yesterday.
Yesterday, going along the first line seemed fine with the wind at my back. Then I turned into the howling gale and snow… The effect was like star-trails in a science fiction movie as the snow blew past me horizontally. Thankfully, the weather got better during the day.
There were some software issues to begin with, but thanks to David Wilborn’s excellent customer support, those were quickly resolved. The results look pretty good. In the next image I have applied a high-pass filter to even out the big changes in range that occur in this data set.
I’ll update you all as I go along. I have six more days to try and complete the whole survey. I suspect I’ll be a little tired by the end.
