Geophysics
Anyone care to offer their interpretation on the data displayed? ;)
Tutorial video for my customers showing how to use the Sensoft Spidar GPR system for IceProfiling, assuming you're already familiar with the IceMap. (Shameless self promotion)
Whenever I dig up an old manual, I contribute to their very useful collection. If you have anything old manuals for old geophysical equipment, send them a note!
With apologies for the colour scheme (I'm so sorry if you're colour blind!). This is the lower layer of a two layer 1D inversion model, interpolated. Was playing with maximizing the contrast to try to find the foundation of the Richardson Mansion that existed on this property prior to it being bulldozed in the 70s and donated to the City of Winnipeg to become Munson Park. I'm pretty sure I captured it in the red square in the middle.
This is my EM34-3XL. Have you ever used one? What was your target? How many years/decades ago was it? ;)
Shameless OC. This is my video of a test I did for an R&D project -- the custom cart and GPR rig.

Tl;dr: Pine Creek, MB investigates GPR anomalies at residential school, finding interesting things but no bodies so far.
Biting my tongue.... "about six inches"
I make little tutorial vidoes for my rental customers. Maybe it's useful to someone :)
This literally used to be my job -- so please ask if you have questions.
If anyone has any geophysical cable horror stories, fire away! > The ideal mix for maximum competitive cable-coiling energy is one A/V tech, one rock climber, one sailor, and one topologist. https://xkcd.com/2810/
One of my ABEM rental customers said they were using this and quite liked it! Anyone used it before?
It's not geophysics unless it runs on batteries and has wires sticking out...
The geophysicist replied without lifting their head up: “Noises? No problem. I got tons of filters here. What’s the frequency?”
Site was being scrubbed from the planet when I was last there -- might not exist at all now.
"The USGS operates a really neat email/SMS earthquake notification service (earthquake.usgs.gov/ens/) that allows fine-grained control of notifications."

Not alarmist, just cool. When I was in grad school we studied we used dInSAR to study groundwater pumping related subsidence. It makes perfect sense that there would be mass redistribution.
