Trouble in Penguin Paradise? UC Research Analyzes Antarctic Ice Flow

UC student researcher uses satellite imagery to calculate ice flow velocity in the coldest place on Earth.

University of Cincinnati student Shujie Wang has discovered that a good way to monitor the environmental health of Antarctica is to go with the flow – the ice flow, that is.

It’s an important parameter to track because as Antarctica’s health goes, so goes the world’s.

“The ice sheet in Antarctica is the largest fresh water reservoir on Earth, and if it were totally melted, the sea level would rise by more than 60 meters. So it is quite important to measure the ice mass loss there,” says Wang, a doctoral student in geography in UC’s McMicken College of Arts & Sciences.

Wang will present her research, “Analysis of Ice Flow Velocity Variations on the Antarctic Peninsula during 1986-2012 Based on Multi-Sensor Remote Sensing Image Time Series,” at the Association of American Geographers annual meeting to be held April 9-13 in Los Angeles. The interdisciplinary forum is attended by more than 7,000 scientists from around the world and features an array of geography-related presentations, workshops and field trips.

Antarctica is 5.5 million square miles of windswept, mountainous ice desert. The fifth largest continent is covered in a sheet of ice that is on average more than a mile thick. Across this province of penguins, outlet glaciers and ice streams funnel chunks of ice into the ocean where they eventually melt in warmer waters. If the ice begins to melt at an abnormally high rate and the sea level rises, a chain reaction of negative ecological effects could take place worldwide.

For her research, Wang uses remote-sensing images recorded by satellites to gather data on Antarctica’s ice motion. She’s particularly interested in determining changes in the ice flow velocity, because the faster ice moves, the faster it’s lost. By calculating that velocity at different time intervals, Wang hopes to further understand the process of ice motion and be able to predict changes to Antarctica’s landscape. She’s planning models that simulate the ice sheet dynamics and estimate any influence on the sea level.

“I hope to provide valuable research to the academia of global change studies,” Wang says.

Additional contributors to Wang’s research paper were Hongxing Liu (UC), Lei Wang (Louisiana State University) and Xia Li (Sun Yat-Sen University, China).

Funding for the research was provided by University Graduate Scholarship allocations from UC’s Graduate School and the Department of Geography.

In 2012, UC was named among the nation’s top “green” schools by The Princeton Review due its to strong commitment to sustainability in academic offerings, campus infrastructure, activities and career preparation. It was the third year in a row that UC earned a spot on the prestigious list.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
