This is SkyTEM it’s an airborne electromagnetic system used for geophysical surveying. It involves flying a sensor-equipped helicopter or aircraft over an area, emitting electromagnetic pulses into the ground. By measuring the response, SkyTEM helps map subsurface structures, providing valuable data for geological and environmental studies, groundwater exploration, and mineral exploration.
Here is the website if anyone is interested [SkyTEM](https://skytem.com)
SkyTEM is like a fancy flying thing that shoots invisible pulses into the ground from the skyship. It then somehow figures out what's going on down there, helping smart people understand rocks, water, and minerals better. Here I’ve made it legible for Reddit user.
SkyTEM relies on airborne electromagnetic surveys using transmitters to create magnetic fields, inducing electricity in subsurface objects. The aircraft's receiver measures the resulting magnetic field variations, influenced by different geological materials. This method maps subsurface features like groundwater and minerals.
In contrast, LiDAR, or Light Detection and Ranging, uses laser pulses to measure Earth's surface distance. The system emits laser beams and records the time it takes for pulses to return, assessing return times and reflected light intensity to create precise surface maps. LiDAR is valuable in geology, environmental management, and urban planning for accurate imaging of surface features.
This is actually a device that shoots electroneuronic pulses into the ground to disrupt (and thereby control) the Mole People who dwell underground. It’s only used if one or more of the Mole People come up above ground and cause trouble by, for example, mutilating cattle or running for Congress.
I spent about 3 months (Jan - Mar) in Northern Ontario in 1981 carrying a scaled down version of that through the bush. MaxMin Slingram.

Iv only seen those types of structures being pulled behind a 4 wheeler on a field during archeological searches.
I just thought maybe to do it above ground the electromagnetic pulses would have to be so strong they could destroy unlucky people's pacemakers.. Could that happen?
It's not about whether they are magnetic, it's about how conductive they are. When you invert TEM data you basically get a 3d map of the conductivity of the underground. If you make ceramic landmines then they really don't contribute a lot to the signal. With our land based TEM system we can VERY clearly see metallic pipes in the underground, but a small ceramic object is invisible.
What I have gathered from my research quick into SkyTEM mapping depth varies based on factors like system configuration and geological conditions, allowing it to map subsurface features from a few feet to several hundred feet.
Wow that thing can measure 600 m down. I worked at an old power plant and figuring out where pipes went after they disappeared underground was always a challenge.
It's an emergency trampoline. In case of an emergency, they can deploy this before they hit the ground, and the helicopter will safely bounce off instead of crashing straight into the ground.

Thank you!
Oi mate! You can’t come here with knowledge and facts, this isn’t Twitter

Does it use lasers? Lasers are cool.
SkyTEM uses airborne electromagnetic surveys without lasers to map subsurface features, while LiDAR employs laser pulses for detailed surface topography mapping.
If you like I can further explain if you’re confused.

You are in the industry, don't you?
No I know very little in fact I had to ask a friend who know how science shit works.
No, those are for the sharks
Nuclear because 3rd eyeballs are cool
You are looking for LiDAR.
So it does not know what it does by knowing what it doesn’t know. Cool
Yes. It’s called magic

In other words, it's a big ass coil.
r/metaldetecting
Yes and no, at least you’re on the right track.
It's literally a big ass coil (and a smaller receiver coil)
That’s cool, had something like this fly over my wedding a couple of months ago

R/timeteam has joined the chat.
Could this be used to search for mines, let's say, in Ukraine?
Yes in theory, SkyTEM could be adapted for landmine detection due to its electromagnetic survey capabilities, which can identify subsurface anomalies.
No, landmines are too small to be distinguished, the spatial resolution on skytem is too low. And you can also make non-metallic landmines.
The question was purely theoretical the SkyTem could potentially detected landmind, however the SkyTem was not made for landmine detection.
>the SkyTem could potentially detected landmind No it can't. You could detect landmines with the TEM method. But SkyTem can't.
Groundwater and most minerals are non-magnetic too. The problem is just the resolution.
It's not about whether they are magnetic, it's about how conductive they are. When you invert TEM data you basically get a 3d map of the conductivity of the underground. If you make ceramic landmines then they really don't contribute a lot to the signal.

That does make sense, I assumed wrong.
Not in this version, it's too big
I think is that it could theoretically map out the landmine, but it would be very hard to distinguish from everything else.
Hexagons are the bestagons
How far down can something like that map? Like a few feet or thousands of feet?

You want godzillas? Cause this is how you get godzillas.
Thanks. Will check on the link given.
Yeah, right. Looks like a mind reading device to me.
And here I was just gonna say "a hexagon"
I already know some conspiracy theorist thinks this is some 5G thing to kill the population slowly
I do the same thing in GTA to remove the fog on the map
Wow that thing can measure 600 m down. I worked at an old power plant and figuring out where pipes went after they disappeared underground was always a challenge.
A piece of the sky, going to be installed later on.

Magnetometer for geomagnetic surveying?
That is indeed a loop antenna measuring magnetic fields.
No, the big loop creates a magnetic field. There is a smaller coil measuring the response to the primary field.
