Over 100 members of the International Thwaites Glacier Collaboration met in Boulder, Colorado in June 2022. Teams from across the UK, US and Korea, re-connected at the University of Colorado, both in person and online, for the first time since before the pandemic for a week-long meeting.

Two crucial glaciers in West Antarctica may be losing ice faster than they have over the last 5,000 years, according to a new study published June 2022.

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.
