Lucas Zoet's primary field of research focuses on understanding the physics of glacier motion through field observation, laboratory experiments, and theoretical analysis. His work sits at the intersection of glaciology and glacial geology. He uses a variety of geophysical and geological methods to explore glacial processes in modern glaciers as well as landforms left behind by Pleistocene glaciers. His role in GHOST is to use the passive seismic observations to understand how Thwaites is slipping.

Alie Lepp is a current Ph.D. student in the Department of Environmental Sciences at The University of Virginia. Her research with THOR will involve examining recent history of subglacial processes, specifically meltwater discharge events, through sedimentological analyses. 

Bernd Kulessa is Professor of Geophysics in the Glaciology Group at Swansea University, UK, and the Director of Research for Swansea's College of Science. His research focuses on the use of applied geophysics to investigate the response of the world’s ice masses to past, present, and future climatic change, and to address related scientific problems of anthropogenic impact. As a UK co-investigator on the GHOST project he will conduct magnetotelluric geophysical surveys to improve our knowledge of the geothermal and hydrological conditions beneath the Thwaites Glacier, fundamental boundary conditions for numerical modelling of isostatic rebound and ice flow.

Richard Alley supports the GHOST project through model development and synthesis.

Nick Holschuh assists in radar survey design, processing, and interpretation.

Nathan Stevens is a graduate research assistant for passive seismic data acquisition, processing, and analysis. He focuses on using earthquake seismology methods to investigate basal mechanics and dynamics of Thwaites Glacier.

Robert Bingham is Head of the Global Change Research Institute. Rob’s research uses a wide array of geophysical, remote sensing and modelling techniques to unravel contemporary glacial change and processes, and to link modern subglacial environments and landforms to deglaciated landscapes. As a member of the GHOST team, he will travel to Antarctica to lead radar data acquisition on Thwaites Glacier to investigate and quantify the sediment, hydrology and subglacial geomorphology, and work with ice-sheet modellers to implement this information into forward projections of ice-sheet behaviour.

Dustin Schroeder leads radar sounding instrument development, data analysis, and interpretation for the TIME project.

Coen Hofstede is a member of Alfred Wegener Institute's (AWI) field glaciology group with more than two decades of experience in scientific and industrial applications of reflection seismics. His focus lies on small-scale active seismic surveys on Greenland Outlet Glaciers and Antarctica. He is in charge of AWI's seismic equipment. During the GHOST traverses, he will operate the vibroseismic source and seismic streamer to image the basal structure of Thwaites Glacier. That equipment is tailor made for such an operation and combines a seismic vibrator with a snowstreamer, towed by a tracked vehicle from shot location to shot location.This enables them to record around 20 km of profiles per day. He will perform subsequent data processing and interpretation, determining basal properties (acoustic impedance) and subglacial geologic structure.

Olaf Eisen is head of the field glaciology group at the Alfred Wegener Institute and a professor for glaciology at the University of Bremen. With two decades of experience of applying geophysical techniques on glaciers and ice sheets, he heads a team in charge of operating the Alfred Wegener Institute's vibroseismic source and seismic streamer during the GHOST traverses. These processes aim to continuously map the subglacial structure in the survey area of Thwaites Glacier. The team's equipment is tailor-made for such an operation, and combines a seismic vibrator with a snowstreamer, towed by a tracked vehicle from shot location to shot location. This enables the team to record around 20 kilometers of profiles per day. They will perform subsequent data analysis and interpretation to determine basal properties and subglacial geologic structure.
