Colder-than-normal Lake Superior could push up water levels

A University Record article written by Jim Erickson describes recent findings on Lake Superior from a research team that includes adjunct professor Drew Gronewold.| Short Read

“Surface-water temperatures above the deepest parts of Lake Superior are expected to be at least 6 degrees Fahrenheit colder than normal by August, delaying the onset of the evaporation season and raising water levels at a faster-than-normal clip,” states the article.

Reduced evaporation on Lake Superior could result in water-level gains of up to 10 inches by next spring, although a lot will also depend on precipitation totals, John Lenters told the Record. Lenters is the leader of the research project and a senior scientist at Ann Arbor-based LimnoTech, an environmental consulting firm founded by CEE alumnus Paul Freedman.

Lenters, Gronewold and their colleagues presented their research in a session titled, “Hyrdorclimatic Variability in the Great Lakes Region and its Impact on Aquatic Ecosystems” at the International Association for Great Lakes Research conference in Hamilton, Ontario in May.

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
