Sarah Thompson

Research Associate

Room 317.19 , IMAS Salamanca

Dr Sarah Thompson is a Research Associate in glaciology as part of the Australian Antarctic Program Partnership at the Institute of Marine and Antarctic Studies. She is interested in hazards associated with ice shelves, glaciers and snowpacks in a changing climate. Particularly in developing and adapting approaches to allow the prediction of change in the natural environment, and the assessment of risk to society on a local and global scale. Her current research focuses on developing remote and field-based techniques to investigate ice shelf stability and glacier crevasse detection for both scientific and field safety applications.

Biography

Prior to her position at IMAS, Sarah attained two post-doctoral research fellowships, a Marie Curie Intra European Fellowship working at the University Centre in Svalbard (Norway) focussed on investigating hazards on downwasting debris-covered glaciers in the Himalayas, providing an improved methodology for glacial lake outburst flood risk assessments in mountainous regions. More recently an AXA Postdoctoral Fellowship based Swansea University (UK), to investigate Antarctic ice-shelves stability through a first-order vulnerability analysis for likelihood of Pan-Antarctic ice-shelf disintegration, ranking ice-shelves in probability of collapse and potential magnitude contribution to sea level rise. Sarah worked as a post-doctoral researcher at ETH Zurich in Switzerland, investigating the transport and release mechanisms of Persistent Organic Pollutants from retreating Alpine glaciers and developing new approaches to investigate snow hydrology, improving understanding of the risks associated with wet snow avalanches. At the University of Innsbruck (Austria) Sarah worked with high-resolution tri-stereo imagery and digital elevation models to investigating the role of avalanched snow to glacier mass change and developing cold lab geophysical surveys to improve interpretation of field-based, on-ice, geophysical data. Sarah completed her PhD at the University of Swansea in 2012, focusing on early recognition and mitigation of glacial lake outburst hazards in the Himalayas.

Research Themes

Sarah’s research focus aligns with the University’s research theme of Marine, Antarctic and Maritime. To date she has applied her expertise to a number of glaciological questions, including the investigation of (i) the role of ice fractures and suture zone in ice shelf stability in East Antarctica, (ii) ice shelf hydrology and dynamics in East Antarctica, (iii) mass balance change on both clean ice and debris covered glaciers in the European Alps, Himalayas and Svalbard, (iv) the response of debris covered glaciers to climate change with implications for flood risk and water scarcity, (v) snow pack hydrology and wet snow avalanche prediction in the European Alps and (vi) the structural and geotechnical properties of glacial moraine dams.

Her current research focuses on ice shelves and their role in the contribution of the East Antarctic ice sheet to future sea level rise. She uses remote, airborne and field data to investigate factors affecting ice shelf stability, particularly characterising ice fracture and snow and ice properties. Over the last two years she has been testing a number of integrated methods to compliment and improve existing approaches to crevasse detection, trailing a new helicopter-mounted radar system used in combination with satellite radar data and ground-based measurements. Working closely with the Australian Antarctic Division, Sarah has been conducting operational trials with the new system, focusing on field safety and scientific applications in the upper few hundred metres of firn and ice. Sarah is also working on developing approaches to improve interpretation of field-based geophysical measurements, with a current focus on time-domain reflectometry of marine ice cores to improve analysis of seismic and radar data collected over ice shelves and a view to future EM exploration of suture zones.

Sarah has carried out extensive field campaigns in Antarctica, Svalbard, the European Alps and the Himalayas, successfully implementing a suite of surveys and techniques, a number of which were applied in these environments for the first time, including, electrical resistivity tomography, self-potential, ground-based and airborne ground penetrating radar, passive seismic, sonar, dGPS mapping, mass balance measurements and speleological investigations. For many of the expeditions she lead not only the scientific aspects of the work but also organised all planning and logistics, managing each with carefully thought out risk assessments, realistic goals and detailed financial management to ensure the safety of all participants and the fulfilment of the project aims.

Collaboration

Sarah is currently involved in a number of international research projects aimed at better understanding changes in Antarctic ice shelves and glaciers and their role in buttressing the Antarctic ice sheet. These projects involve collaboration between a number of universities and research institutes across Europe, North America and Asia.

Description
The AAD has a requirement for four instruments systems to monitor glacier flow and sea level with integrated remote power and telemetry technology (GNSS installations). The GNSS installations are needed for preparation for deployment in field season 22/23. The units will measure the flow rates and vertical changes in ice shelf melting and test the applications of GNSS reflectometry techniques for measurements of sea surface height. AAPP has the direct expertise and experience developing bespoke instrumentation suites designed for remote deployments in harsh Antarctic conditions.
