latest news


Greentracs 2017 is underway! Bob, Gabe, and Karina have joined colleagues from Boise State University on an 8-week snowmobile traverse in the Western percolation zone of Greenland! Check out new posts on the GreenTrACS blog!


Ian Lee and David CS are deploying to Jarvis Glacier, Alaska, to deploy tilt sensors and run optical televiewer logs in boreholes drilled along the shear margin of the glacier!


David CS is on his way to the Antarctic for the third time! He'll be deploying as part of the South Pole ICE core (SPICE) project this season.


Erich Osterberg, Gabe Lewis, and Thomas Overly have returned from Greenland and a highly successful first year of the GreenTRaCs traverse! See the full story on Gabe's blog!

Thomas Overly


Thomas completed a masters in Geography from the University of Kansas (2010), where he used near-surface radar data to derive accumulation rates near Summit, Greenland. During his masters, he earned a Fulbright Grant to Denmark, hosted by the University of Copenhagen's Centre for Ice and Climate. Various research projects in Greenland have taken him to Upernavik Glacier, Jakobshavn Glacier, Summit Station, NEEM Deep Ice Core, and multiple settlements along the west and east coasts of Greenland. Prior to his arctic interests, Thomas completed a B.S. in Geography from Northern Arizona University (2004)

Alexandra Giese


Ali is a first-year PhD student in the Glaciology Research Group. After conducting undergraduate and post-grad work on past climate and mountain glacier fluctuations, Ali was interested in learning about effective science communication, policy development, and business initiatives surrounding climate change. She hopes to draw from and build on her experiences with environmental NGOs as a fellow in Dartmouth's IGERT program on Polar Environmental Change. Ali is generally interested in glacier modeling, ice sheet stability, and the sociopolitical implications of melting ice and rising seas; she will be working with Bob as part of an international team investigating the deglaciation history of the Ross Sea embayment, which will help contextualize current and future responses of the West Antarctic Ice Sheet to climate change.

Kristin Schild


Kristin is a first-year PhD student in the Glaciology Research Group. Her background is in physics (undergrad at Southern Methodist University, TX) but moved to Hanover from Maine, where she did her Masters. While at UMaine, she was able to study tidewater glaciers in Greenland, Antarctica and Alaska, but focused her research on determining the environmental controls on tidewater outlet glaciers in Greenland through remote sensing and in situ measurements (GPS, Met stations, Seismic Stations, Time-Lapse cameras). She also worked on constraining the point of origin for glacial earthquakes through a remote-sensing terminus position time series. While at Dartmouth, she will work on Dr. Hawley's margin stability project trying to determine the sub-glacial hydrology of Jakobshavn Glacier, West Greenland. She is broadly interested in the Glacier dynamics of tidewater outlet glaciers and studying them through in situ and remote sensing techniques. Kristin grew up in Chicago and enjoys being outdoors- if she ever has any free time, you can generally find her ice climbing, rock climbing or kayaking!
