Sampling bedrock beneath the ice sheet, GHC will identify if and when the glacier retreated in the past, how it recovered, and how it is currently responding to environmental conditions.

Investigating sediments deposited in the seas near the glacier, Thwaites Offshore Research (THOR) will reconstruct past changes in environmental conditions and the glacier’s response to these, thereby adding context to our projections of future change.

Measuring ocean circulation and thinning beneath the floating part of the glacier using state of the art technology such as AUVs and automated land-ice stations, TARSAN will investigate how the ocean and atmosphere are affecting the glacier.


ITGC's Ted Scambos describes the program's research on Thwaites Glacier in an article written for The Conversation.

Antarctica is where I work. As a polar scientist I’ve visited most areas of the ice sheet in more than 20 trips to the continent, bringing sensors and weather stations, trekking across glaciers, or measuring the speed, thickness and structure of the ice.

Dr. Rebecca Pearce is a post-doctoral fellow at Simon Fraser University, with a speciality in using the magnetotelluric method to locate geothermal resources in a terrestrial context. She will be working with Swansea University on team GHOST to apply these techniques to resolve the geothermal and hydrological regimes on Thwaites glacier, to improve accuracy in the ice flow and isostatic rebound modelling for the glacier.

Ole Zeising is a geophysicist and glaciologist working at the Alfred Wegener Institute. His research focuses on investigating ice sheet dynamics using active geophysical methods. As part of the GHOST team, he will assist with the acquisition and analysis of a seismic survey of Thwaites Glacier, using a vibrator source to create a continuous profile of the subsurface along the GHOST traverse.

TIME field teams retrieve seismic, GPS, and radar data from Thwaites' eastern shear margin


There was a whole lot of digging during this Antarctic summer season (2021-22) at the Eastern Shear Margin (ESM) of Thwaites Glacier by ten intrepid International Thwaites Glacier Collaboration (ITGC) scientists and mountaineers. Two Thwaites Interdisciplinary Margin Evolution (TIME) field teams - one deployed through the British Antarctic Survey (BAS) and one deployed through the U.S.

ITGC's Field and Ship Best Practices document describes recommendations for best practices for field- and ship-based scientific campaigns in Antarctica, undertaken as part of the International Thwaites Glacier Collaboration (ITGC). Its intended audience is all members of the ITGC’s field and ship teams, regardless of career-stage, role in the team, seniority, or previous experience. These best practices are based on evidence from the behavioral science and psychology literature and intended as suggestions to help teams improve the climate of their field and ship teams.
