Professor Gronewald explains Great Lakes levels rebound

Adjunct Professor Drew Gronewald spoke with Michigan Radio’s Environment Report about the Great Lakes water level recovery.| Short Read

According to a recent brochure from NOAA’s Great Lakes Environmental Research Laboratory (GLERL), 2014 saw the second above-average seasonal rise on Lakes Superior, Michigan and Huron.

This comes as a surprise since the brochure also states there were record low water levels in January 2013.

“The quick recovery has stifled an effort to engineer a solution to the problem of low lake levels in Huron and Michigan,” the article states.

Professor Drew Gronewald, told Michigan Radio that the lakes were low mainly because of evaporation.

“It’s really that sustained high water loss through evaporation that we believe kept water levels low despite, in fact, above average precipitation for much of this time,” he said.

Michigan Radio also interviewed those interested in engineering a solution to the extreme water levels.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
