Investigating the polar regions from the inside out

Meet the Researchers

Terry Wilson

Terry Wilson

Principal Investigator
The Ohio State University, USA

Focus of Study
I investigate the structural architecture of the Earth, how continents rift, and the interaction of the solid Earth and ice sheets in Antarctica.

Why Polenet?
Geophysical measurements on this unprecedented scale across Antarctica will lead to phenomenal discoveries - I've spent 10 years working to achieve it!

Favorite Vista
The Royal Society Range, Transantarctic Mountains, from Ross Island, Antarctica.


Stephanie Sherman

Stephanie Sherman

Graduate Research Fellow
The Ohio State University, USA

Focus of Study
Using GPS and other remote sensing techniques to study crustal deformation in Antarctica.

Why Polenet?
As a PhD student with POLENET, my research utilizes data that has been and will be collected through POLENET.

Favorite Pastimes
Drawing, running, playing outside, and anything involving music or live performing arts. I've also recently become obsessed with yoga!


Eric Kendrick

Eric Kendrick

Senior Research Associate
The Ohio State University, USA

Focus of Study
I use GPS to study crustal motion in Greenland, Antarctica, South America, and the islands of the South Pacific.

Why Polenet?
POLENET is a natural extension of my previous work on the West Antarctic GPS Network (WAGN) project.

Favorite Movie
Toss-up between The Sound of Music and Psycho

Favorite Pastimes
Travel, cycling, kayaking


Bob Smalley

Bob Smalley

Research Professor
The University of Memphis

Focus of Study
I am a geophysicist interested in the dynamics of tectonic processes that cause earthquakes and build mountains and the geodynamics of solid earth-ice sheet interactions. Space-based Geodesy and Seismology are my principal tools.

Why Polenet?
I was drawn to Antarctica by a number of scientific questions, and also the uniqueness of working in Antarctica. The International Polar Year (IPY) brought together a number researchers working in the Polar regions over the past 10-20 years and allowed us to develop a large, integrated, multidisciplinary, and multinational project that would not have been possible without the IPY. In addition to advancing basic science, both these foci also contribute to improving societal hazard mitigation.

Most Interesting Place

Favorite Place

Audrey Huerta

Audrey Huerta

Assistant Professor
Central Washington University

Focus of Study
I'm fascinated by mountains, and I use geology, geophysics, and numerical modeling to figure out how mountains are created and destroyed.

Why Polenet?
Antarctica has some of the world's most magnificent mountain ranges. But since they're mostly covered by ice, we use seismic techniques let us get a better understanding of their structure. By seeing the roots of the mountains, I can start to figure out what tectonic processes are responsible for making them.

Most Interesting Place
Shatter cones from the Vredefort impact structure

Rick Aster

Rick Aster

President, Seismological Society of America
Professor of Geophysics
Colorado State University

Focus of Study
I am a seismologist who is broadly interested in both seismic sources (including novel ones from Antarctica, such as drifting icebergs) and applying seismic methods to image the deep interior of the Earth.

Why Polenet?
Because of my long-standing interests in continental rift zones (e.g., the Rio Grande Rift) and in seismic techniques, such as receiver functions, that are highly applicable to exploring the lithosphere and mantle scale structure of West Antarctica. I also love working in groups with diverse colleagues from other fields, such as geodesy and glaciology.

Favorite Guitarist
Jeff Beck!


Andy Nyblade

Andy Nyblade

President, Seismological Society of America
Professor of Geosciences
Penn State University

Focus of Study
I am interested in understanding deep processes inside the Earth that have formed and continue to modify the Antarctic continent.

Why Polenet?
Seismic images will let us "geophysically" peel off the West Antarctic ice sheet, revealing the structure of the continent for the first time.

Favorite Location
Mt. Kilimanjaro (about 20 years ago before the glaciers started to rapidly melt)


Rob Bauer

Rob Bauer

Associate Scientist
National Snow and Ice Data Center

Focus of Study
I work with a small research team, studying the high plateau, and the fast-warming Antarctic Peninsula and its icebergs, as a Ground Penetrating Radar operator and Field Team mountaineer.

Why Polenet?
I had the opportunity to work with UNAVCO on Polenet this season and couldn't pass up the chance to see some new locales.

Favorite Things
Flying, being in the desert, being on a river.


Samantha Hansen

Samantha Hansen

Postdoctoral Scholar
Office of Polar Programs, NSF

Focus of Study
Earthquake seismology and active tectonics to investigate structure and infer associated earth processes.

Why Polenet?
The seismic data from Polenet will help advance our understanding of rifting and extension in West Antarctica.

Favorite Quote

Yves Rogister

Yves Rogister

Assistant Professor of Geophysics
University of Strasbourg

Focus of Study
The long-term variation of the Earth's gravity field due to post-glacial rebound and present-day ice melting in the polar regions.

Why Polenet?
Observations at permanent gravity stations on Antarctic bases necessitate an international collaboration.

Favorite Sports/Bands/Writers
Cycling, running, U2, Arcade Fire, Queens of the Stone Age, James Ellroy, Pierre Michon, Graham Swift


Sridhar Anandakrishnan

Sridhar Anandakrishnan

Professor of Geosciences
Penn State University

Focus of Study
Glacier and rock interactions: how the underlying rock influences glacier flow and how past glaciations have affected tectonics.

Why Polenet?
Working together we can make seismic and GPS measurements that are needed for understanding key issues about Antarctic and Greenland ice sheet stability. The POLENET team can make that happen.

Favorite Something/Author/Place
Cats!, Jane Austen, Mt. Nemrut in Southern Turkey in midwinter


Julien Chaput

Julien Chaput

Graduate Student
New Mexico Tech

Focus of Study
I'm currently studying seismology on a variety of scales, from volcanic media to continental scale crustal analyses.

Why Polenet?
As part of my PhD dissertation, I'm going to use POLENET data in order to infer details about the crust and mantle below the ice in West Antarctica.

Favorite Hobbies
Rock Climbing, drumming, drawing, throwing tea parties


Jeremy Miner

Jeremy Miner

Polar Network Operations Engineer
UNAVCO

Focus of Study
I am a Polar Network Operations Engineer. I manage the permanent GPS stations from prep, testing, deploying and maintaining.

Why Polenet?
I am a part of POLENET through UNAVCO's role as a technology and support facility. Also because I love the polar regions.

Favorite Things
I love Polar and Alpine regions and anyway I can find to spend time in them is fine by me. I enjoy spending time in the mountains with my family - hiking, climbing, skiing, boating, biking. Soccer is the beautiful game. Chocolate and Cheese are eternal.
