SPRI's mission is to enhance the understanding of the polar regions through scholarly research and publication, educating new generations of polar researchers, caring for and making accessible its collections, and projecting the history and environmental significance of the polar regions to the wider community.
Ice sheets can retreat faster than previously thought possible
6th April, 2023
SPRI-based researchers Drs. Frazer Christie, Sasha Montelli, Prof. Julian Dowdeswell and Evelyn Dowdeswell have published research showing that ice sheets are capable of retreating much faster than previously thought possible.
The research, led by Cambridge Geography and SPRI alumnus Dr. Christine Batchelor of Newcastle University, analysed more than 7,600 subtle landforms called 'corrugation ridges' across the mid-Norwegian seafloor. These landforms revealed that a former ice sheet underwent pulses of rapid retreat totalling up to 600 meters per day at the end of the last Ice Age. This rate is up to 20 times faster than present-day rates of ice-sheet retreat observed from satellites, and suggests that similarly rapid retreat could occur across flat-bedded areas of the Antarctic Ice Sheet in the future.
The research is published as an article in the journal Nature, and further information can be found in the Cambridge University press release.
SPRI Review 2022 is now available online. SPRI Review is the Annual Report issued by the Scott Polar Research Institute, giving information on the Institute's activities over the past year.
New study finds flow of the Greenland Ice Sheet more complex than thought
21st February, 2023
Researchers in the Department of Geography and the Scott Polar Research Institute have identified a highly variable layer of 'warm' basal ice to exert strong control on the flow of the Greenland Ice Sheet.
The basal ice layer is highly deformable and up to 70 m thick in topographic depressions where its deformation explains 90% of the ice sheet's total motion. To study where the basal ice layer forms and how it evolves, the researchers constructed a 3D model.
The results reported in the journal Science Advances could be used to develop more accurate predictions of how the Greenland Ice Sheet will respond to climate change. "Even tiny amounts of liquid water alters the mechanical characteristics of the ice considerably" said first author Dr Robert Law, who completed the work as a PhD student in Cambridge. "The findings challenge the textbook view of how ice sheets move" added supervisor and project leader Professor Poul Christoffersen.
Runaway West Antarctic ice retreat can be slowed by climate-driven changes in ocean temperature
17th January, 2023
An international team of researchers, led by Dr. Frazer Christie, has combined satellite imagery and climate and ocean records to obtain the most detailed understanding yet of how West Antarctica is responding to climate change.
Their results, published in the journal Nature Communications, show that while West Antarctica continues to retreat, the pace of ice melting has recently slowed across its most vulnerable sector in-sync with changes in atmosphere and ocean conditions offshore. Ultimately, the research implies that runaway, ice-sheet-wide collapse isn't inevitable, depending on how the climate changes over the next few decades.
The study was supported by the Prince Albert II of Monaco Foundation, the Carnegie Trust for the Universities of Scotland, the Natural Environment Research Council, the US National Science Foundation, the International Thwaites Glacier Collaboration project and the European Space Agency.
Shackleton's Cabin on BBC iPlayer featuring SPRI Archives
12th January, 2023
Naomi Boneham, SPRI's Archivist appears in the film in interview with Sven Habermann sharing Shackleton's diaries.
On 5 January 1922, world-famous Antarctic explorer Ernest Shackleton died of a heart attack in his cabin aboard The Quest during his final expedition to the South Pole. Shackleton's Cabin follows Sven as enthusiast Sven Habermann rebuilds the cabin and explores the life and final days of his hero.
