Erich Osterberg is a professor at Dartmouth College and is the lead PI on this project. His overarching research objective is to understand how and why Earth’s environment changed in the past, and is changing today, so we can more accurately predict how it will change in the future. His specialty is creating records of past climate change and air pollution by analyzing chemical markers preserved in glacier ice cores. Erich is particularly interested in how glaciers responded to warm periods in the past, as this provides an example of how glaciers and sea level may respond to future global warming.

Bob Hawley is a professor at Dartmouth College and a co-PI on the GreenTrACS project. He started working as a glaciologist in 1995, as an undergraduate at the University of Washington, through the National Science Foundation 'Research Experience for Undergraduates' (REU) Program. Following the completion of his BS degree he continued in glaciological research by participating in the inaugural winter-over at Summit camp, Greenland, during the 1997-1998 boreal winter. He earned a Ph. D. in geophysics from the University of Washington in 2005. His research interests include: the physics of firn densification, mass balance of large ice sheets, interpretation of ice core records, and remote sensing. He has worked primarily in East and West Antarctica and Greenland.

Hans-Peter (HP) Marshall is an assistant professor in the Department of Geosciences and the Center for Geophysical Investigation of the Shallow Subsurface (CGISS), at Boise State University, and an expert consultant for the U.S. Army Cold Regions Research and Engineering Laboratory. HP is a snow scientist and glaciologist who uses geophysics and engineering tools to study the Cryosphere. He received his B.S. degree in Physics from the University of Washington (1999), with a minor in Geophysics, and a Ph.D. in Civil Engineering with an emphasis in Geotechnical Engineering from the University of Colorado at Boulder (2005). He was a visiting Ph.D. student for one winter at the Swiss Federal Institute for Snow and Avalanche Research (2004), and recently received the 2010 AGU Cryosphere Focus Group’s Young Investigator Award. His current research is focused on spatial variability in snow and its effect on remote sensing, snow hydrology, and snow avalanches.

Gabe Lewis is a third year PhD student at Dartmouth College focusing on the spatial and temporal variability of accumulation and albedo of the Greenland Ice Sheet. He uses a combination of radar platforms on airplanes, albedo measurements from satellites, regional and climate models, and fieldwork. Gabe studied geosciences and physics at Williams College (2013) and has conducted glacial research in Alaska, Nepal, Italy, New Zealand, and is excited to study in Greenland. He comes to Dartmouth after a 2600-mile thru-hike of the Pacific Crest Trail. 

Tate Meehan is a second year M.Sc. Candidate of Geophysics at Boise State University focusing on the application of multi-offset ground-penetrating radar to derive firn density, water equivalence, and accumulation estimates of the Greenland Ice Sheet. Tate received his B.Sc. in Geophysics with a Minor in Mathematics from Texas A&M University (2014). His previous research interest has been on the application a magnetic and electromagnetic methods for subsurface imaging.









Karina Graeter is in her second year pursuing a Master's of Earth Sciences at Dartmouth College. Her research investigates how firn and surface processes impact the surface mass balance of the Greenland Ice Sheet. Karina received her B.A. in Physics and Earth & Oceanographic Science with a minor in Music at Bowdoin College (2014). Her previous research ranged from studying small scale atmospheric physics to the magma system dynamics of New Zealand's volcanoes.

Forrest McCarthy: Having worked as a professional mountain, river and polar guide for twenty-five years Forrest has participated in more than twenty research expedition in the Arctic and Antarctic. Forrest holds a BA in Outdoor Education from Prescott College and a Masters in Geography from the University of Wyoming where he examined climate induced land-cover change in Arctic Alaska.
