Semester 1 is over. Goodbye, Surprise-4000-Word Assignment and 2000-Word Report on Planning A Project.
The plan I wrote basically involved driving a GPR over a disused cemetery where all the markers are missing (aka a Pioneer Park), then plug that data into computer software and create a rainbow “heat map” where all the old burials are.
You see, GPRs normally produce images called radargrams. Radargrams do not look dissimilar to grey TV static, and require a human interpreter to scrutinise patterns + see if they can detect changes in the masses of grey lines to find subsurface stuff. (Anyone who Google Image searches ‘GPR data’ will see examples of what I mean).
In contrast, below is an example of what a computer-modelled gravesite looks like (Minecraft anyone?):
Buried objects and people should become harder to miss when they are plotted intuitively like this. So this can be useful for forensic scientists too.
I borrowed the idea for this assignment, and that image, from this paper.
Just before I hit submit, I realised the marking rubric said the project had to span 4 weeks. With no good sense of how long archaeology projects take, I had written a lovely long Timeline that would have allowed project participants to dally around for 3 months getting materials together. Had to rewrite that section quick-ish.
Other things which have been happening:
• I found an old piano going second hand for $250, and have been noodling around on that.
• People at work know I’m enrolled in a certificate in Archaeology. I had only said that I had tagged along with researchers on a study when I took annual leave, but ex-students from the uni put 2+2 together. So it’s not really a secret now. Coworkers are pretty good about it. Only Corporate doesn’t know (yet)
• For the second time in my life, I have submitted an application to med school. This is an old dream. It took 15 minutes and was anticlimactic. Now I’m older and have learnt more things, I am okay with whatever the outcome is. We’ll see what happens.
Hope everyone is healthy, happy and well.
