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.

Jamin Greenbaum's research focuses on the acquisition and analysis of geophysical and oceanographic data to enable improvements to our understanding of Antarctic land-ice-ocean interaction processes in areas sensitive to rapid inland retreat. Specific interests include the impact of subglacial freshwater discharge on grounding line and ice shelf stability, and geological controls on ice sheet dynamics, especially the impacts of tectonics and geothermal heat flux. Additional interests include the development of low-carbon alternative platforms and approaches, especially those enabling the acquisition of data in typically difficult or inaccessible areas.

Irena Vaňková is a polar scientist working in the area of ice-ocean interactions. In 2018 she finished her PhD under the guidance of David Holland at the Courant Institute of Mathematical Sciences at New York University. After that she spent two years as a Marie-Curie Fellow at the British Antarctic Survey, where she continues to work as a physical oceanographer.

Naomi Ochwat (she/her) is a PhD student in the Department of Geological Sciences at the University of Colorado Boulder. Her research focuses on using remote sensing observational data to investigate the Marine Ice Cliff Instability (MICI) hypothesis, including fracture processes, calving, and the role of sea ice melánge. Her role in ITGC is to provide real-world parameters to help constrain ice cliff models and subsequent MICI projections.

Lily Green provides administrative support for the Science Coordination Office.

Jenny Suckale leads the modeling component for the TIME project.

Laura Glastra is a Ph.D. student in Physical Oceanography at the University of Rhode Island's Graduate School of Oceanography. Her research focuses on gas exchange processes in polar regions, specifically how noble gases are partitioned between sea ice and seawater during freezing. She is currently carrying out laboratory experiments to provide further insight to this process. On the 2022 TARSAN cruise she will be collecting samples of seawater for isotopic analysis of noble gases, which can be used as physical tracers to help identify water masses such as glacial meltwater.


As world leaders come together next month for the 26th UN Climate Change Talks of the Parties (COP26) in Glasgow, UK, sea-level rise will be on the agenda for countries with low-lying areas looking at how to manage rising seas. Today (11 October 2021) a new film launches to highlight how the International Thwaites Glacier Collaboration, of around 100 scientists from the US, UK, Germany and Korea, are aiming to reduce the uncertainty of sea-level rise from the mighty Thwaites Glacier in West Antarctica.
