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

Alexandra is a PhD candidate in the Glaciology Research Group. After conducting undergraduate and post-grad work on past climate and mountain glacier fluctuations, Alexandra was interested in learning about effective science communication, policy development, and business initiatives surrounding climate change. Her experiences with two different NGOs after college taught her the social, economic, and political relevancy of her academic passions, glaciology and climate. Earlier in graduate school, Alexandra researched the sea level rise contributions of Greenland and Antarctica through energy modeling and ice coring, respectively. Currently, she is exploring in the energy balance of the debris-covered glaciers in the Himalaya and the physical characteristics of the debris layers on their surfaces. She enjoys both modeling and field work and is motivated by the need for better projections of the impacts of rising seas and melting mountain glaciers.

Ian Lee

Ian is a second year Master's student specializing in extreme environments sensor engineering and data analysis. Having completed his undergraduate in geophysics at the University of Washington, Seattle in 2016, Ian joined the Glaciology Research Group to both gain field experience and expand his involvement in the glaciological community, having done an internship at the Norwegian Polar Institute in 2015 digitizing ice shelves along the coast of Dronning Maud Land, Antarctica. His work at Dartmouth involves the engineering of tilt sensors equipped with 3-axes accelerometer and magnetometer and the development of a full-fledged extreme environments tilt sensor system for deployment on the polythermal Jarvis Glacier, Alaska in order to obtain the strain measurement du/dz to calculate the velocity field directly downglacier and create deformation regime maps in the vicinity of boreholes drilled primarily along Jarvis' shear margin. Having completed his first field season on Jarvis in March-May 2017 and having obtained a working dataset from the return field season in July 2017, Ian is interested in utilizing big-data management techniques and analysis to compare the observed local deformation regime of Jarvis to theoretical expectations and develop preliminary insights into calibrating the constitutive flow law for ice for glaciers of differing thermal basal regimes.
