Trouble in Penguin Paradise? UC Research Analyzes Antarctic Ice Flow

09.04.2013
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.

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...

Im Focus: Scientists improve forecast of increasing hazard on Ecuadorian volcano

Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).

The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
