Alberta's hidden valleys offer both resources and danger

16.11.2009
Alberta is crisscrossed with hidden glacial valleys that hold both resource treasures and potential danger. University of Alberta researcher Doug Schmitt discovered a 300 metre deep, valley hidden beneath the surface of the ground near the community of Rainbow Lake in northwestern Alberta.

The valley was created by glaciers and over time filled with loose rock gradually disappearing from the landscape.

There had already been extensive underground mapping of the area, but Schmitt went beyond the standard practices to locate the valley. He combined a variety of the existing seismic and electrical mapping data and found the valley. It ranges between two and three kilometers in width.

If these hidden alleys go undetected by standard underground mapping practices there could be serious consequences. Schmitt says if a tailings pond were unknowingly put in an area like this and the liner failed, the effluent could spread far and wide, underground via the aquifer.

And then there's the issue of pockets of natural gas lying in the porous rock just metres beneath the surface. An energy exploration crew could trigger an explosion and fire. Schmitt says it's happened more than once in Alberta.

Schmitt says there are hidden valleys like his find near Rainbow Lake, all over Alberta.

Schmitt is Canada Research Chair in rock physics. Schmitt co authored a paper on the Rainbow Lake discovery. It was published by the Geological Society of America.

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
