I am seeking a physical explanation for this;
There is huge amount of such a Forest rings in Earth; (Link to Google Maps to one ~400 m Ring)
They range in diameter from 30 metres to 2 kilometres, with the average ring measuring about 91 metres across. Over 2,000 of these forest rings have been documented, but scientists estimate the actual number is more than 8,000. Forest rings in Canada
My question relates to following observation;
There seem to be giant electromagnetic disturbances in the soil and subsoil that affect not merely growth of vegetation over large areas but also the level of the water table: it rises “against” gravity within the circle.
Behind the link in the given link it's said more clearly;
But it gets weirder: as Hamilton’s fieldwork also revealed, there is a measurable “bulge in the water table that occurs over the entire length of the forest ring with a profound dip on the ring’s outer edge.” For Hamilton, this effect was “beyond science fiction,” he remarked to the trade journal Northern Ontario Business, “it’s unbelievable.”
What this means, he explained, is that “the water is being held up against gravity” by naturally occurring electrical fields.
And further from The Journal Ontario Business;
Hamilton was testing an analytical technique over a Matheson gold deposit to determine if there was any kind of geochemical surface signal. To his surprise, there were signals coming through 30 to 40 metres of glacial clay.
“We’re thinking there’s no way metals can move through clay 10,000 years after glaciation.”
After ruling out transport by ground water, diffusion and gas, he theorized it had to have been lifted to surface on electrical fields. He applied the same theory to forest rings and discovered that they were also giant negatively charged cells.
Water does react to magnetic field. But the needed $10T$ to make it lavitate is way too much compared to Magnetic field earth provides; it's just $0.00005T$ and we should be talking only some reasonable scale variations here.
QUESTION; Why is ground water rising on these forest rings? The most obvious one would be dissolved gases. And this paper does provide information to this direction. But with closer study, the influence of the gases can be only 0.16 ppm. This means that the density change must come from water temperature. It can't come from the Ice deep below the ground. There is a measured temperature drop in the edge of the ring, but the inside outside of the ring seems to have approx. the same temperature near the soil surface.
It's hard to see how coverd ice would explain the perfect ring shape (up to 2 km in diameter!)? and the landscape is not even flat. (Pingo's formates in dried lakes/flat grounds) And why there is up to 2 meters soil depression in the annulus? Why there is negative reduction anomaly in the center of the rings? There seems to be some Ice deposits in the ring edge.
To point out the Physical problem of this; Rising ground water with 10 cm on $r=1km$; $A=3140000m2$ area needs quite huge continuous power source.
