Farmers opt mistakenly for unsuitable agricultural terrain

Usage examples of permafrost.

But more confusing were the changes in surface features wrought, in that frigid periglacial land, by permafrost.

Water began to pool as the thin layer of permeable soil above the level of the subterranean permafrost became saturated.

It was only a prolonged storm in Chrystianaville, but out in the countryside, a previously habitable strip of land was either being scorched barren by blasts of superheated air or turned into permafrost by sub-zero gales.

Sure, if you can guarantee us permafrost near the surface, maybe, just maybe, we could carry enough solar cells to set up airmakers and hydrolyze water to get oxygen.

They would creep irresistibly from the moist craters of the iceteroid impacts, proliferating relentlessly amid the storms and earthquakes of terraformation, surviving the floods as permafrost melted.

Beyond lay the crusted ridge of permafrost that had built up in the warring crosswinds of the Euston Road.

Even a small meteorite, like the one we found in Antarctica, would hit the ground with enough energy to liquefy the permafrost if the ice is only a meter or so beneath the surface.

A first-class cabin to themselves, day trips to resort centres, the eager buzz of third-class passengers on their way to a new life on homesteads springing up behind the retreating permafrost.

Mining the liquid aquifers directly, and also melting the permafrost with explosives, probably nuclear explosives, and then collecting the melt and pumping it onto the surface.

Vola-tiles from below had seeped up and cooled, and the water portion of the volatiles had pooled in liquid aquifers, and in many zones of highly saturated permafrost.

Nothing could be much more inappropriate than palm-tree symbols on a planet with sixty feet of permafrost, Bordman reflected.

The real barrier was the permafrost that lies beneath the surface of all large governments, no matter what name they go by: layer after frozen layer of official indifference to any project not close to home in some way, and not likely to pay off—.

From beneath the thawing permafrost of Siberia, billions of tonnes of methane and other greenhouse gases are already being released.

The pink-gold magess hoisted her skirts and tramped through the permafrost to his.

Jenny Dickens suggested that the methane was released from deposits of methane hydrates in permafrost and on the seabed.
