# Fibre-optics used to take the temperature of Greenland Ice Sheet

RESPONDER team members installing borehole sensors after drilling to the bed of Store Glacier (Rob Law and RESPONDER team)

Scientists have used fibre-optic sensing to obtain the most detailed measurements of ice properties ever taken on the Greenland Ice Sheet. Their findings will be used to make more accurate models of the future movement of the world's second-largest ice sheet, as the effects of climate change continue to accelerate.

The research team, led by Dr Poul Christoffersen from the Scott Polar Research Institute, used a new technique in which laser pulses are transmitted in a fibre-optic cable to obtain highly detailed temperature measurements from the surface of the ice sheet all the way to the base, more than 1000 metres below.

"With typical sensing methods, we can only attach about a dozen sensors onto the cable, so the measurements are very spaced out," said first author Robert Law, a PhD candidate at the Scott Polar Research Institute. "But by using a fibre-optic cable instead, essentially the whole cable becomes a sensor, so we can get precise measurements from the surface all the way to the base." The researchers found three layers of ice in the glacier. The thickest layer consists of cold and stiff ice which formed over the last 10,000 years. Below, they found older ice from the last ice age, which is softer and more deformable due to dust trapped in the ice. What surprised the researchers the most, however, was a layer of warm ice more than 70 metres thick at the bottom of the glacier. "We know this type of warm ice from far warmer Alpine environments, but here the glacier is producing the heat by deforming itself," said Law.

# Professor Julian Dowdeswell

Professor Julian Dowdeswell retired from the Directorship of the Scott Polar Research Institute at Easter 2021 after almost 20 years in the post. He will remain as Professor of Physical Geography and a member of SPRI during a period of sabbatical leave prior to retirement from the University of Cambridge at the end of 2022.

During a career of over four decades, since his graduation from the Cambridge Geography Department in 1980, Julian has led or participated in more than 40 expeditions to the Arctic and Antarctic. His research, published in almost 400 papers, is centred in two main themes. The first concerns the patterns, processes and rates of glacial sedimentation on high-latitude continental margins, from fjords and continental shelves to the deep sea, and the record of past glacier and ice-sheet change found there. The second is the form and flow of modern glaciers and ice sheets, their sensitivity to climatic variations and the implications for global sea level.

In terms of highlighting environmental issues concerning the changing icy world to wider audiences, from decision-makers to the general public, Julian has also made wide-ranging contributions; co-authored books include 'Islands of the Arctic' and 'The Continent of Antarctica'. He has spoken a number of times to members of both Houses of Parliament, has been an invited speaker on issues concerning ice and environmental change at, for example, the World Economic Forum in Davos and the Nobel Dialogues in Stockholm and was a UK delegate at the 2016 White House Ministerial on the future of the Arctic.

He also represented the UK for almost 10 years as delegate to the councils of the International Arctic Science Committee (IASC) and the Scientific Committee on Antarctic Research (SCAR). Beyond academia, Julian is also a Trustee of the Royal Museums Greenwich.

Julian says of his time as SPRI Director: 'I have very much enjoyed the challenges of being the Director of the Scott Polar Research Institute. It has been a privilege to have undertaken research in the Arctic and Antarctic and their surrounding seas on a regular basis and to have been able to work with a series of very able research students and post-docs over this period. A key continuing role for the SPRI is to train the brightest and best to take forward our understanding of polar environmental change; the Centenary Fundraising Campaign is an important contribution to this. I also value the collections of the Institute greatly – our wonderful Library, Archive, Museum and Picture Library. One particular benefit of being Director is the opportunity to get to know these collections and, indeed, to show visitors the breadth, depth and quality of our holdings. Wider outreach through SPRI's contributions to the centenaries of the 'Heroic Age' expeditions has also been memorable through, for example, services of celebration and remembrance in St Paul's Cathedral and Westminster Abbey. It has been a fulfilling twenty years as SPRI Director - as has been my whole career spent in Cambridge, Bristol and Aberystwyth universities.'

# Daughters of the Snow (BBC Sounds and Radio 4)

A BBC Sounds / Radio 4 program, "Daughters of the Snow", broadcast this week and available to listen online, featured Dr Michael Bravo.

This collaboration between Dr Bravo, radio producer Andrea Rangecroft, and the artist and poet Himali Singh Soin, explores the North Pole as a mythologised space in literature. Reading novels like Mary Shelley's Frankenstein and Arthur Conan Doyle's Captain of the Pole Star at school in India, the North Pole has often been portrayed as a blank, white, mysterious and uninhabited place. The conversations in this programme, set to music, discuss the consequences of mythologising this huge region of diverse lands and cultures at the top of the world.

# Greenland Ice Sheet lakes drain in the winter

Ian Willis

PhD student Corinne Benedek and supervisor Ian Willis have discovered that large lakes on the surface of the Greenland Ice Sheet drain in the Arctic winter. They used satellite radar images to identify large, anomalous, sudden and sustained increases in radar backscatter, showing a switch from a water to an ice surface.

It is known that lakes can drain catastrophically in the summer but this is the first time they have been seen to disappear in the winter.

Using other satellite data they confirmed the lake drainages, which show a lowering of the surface by several metres and the loss of up to 20 million cubic metres of water, the equivalent of around 8000 olympic size swimming pools emptying to the bottom of the ice sheet over a few days, possibly just a few hours.

The findings have implications for the speed at which the ice sheet flows to the ocean.

The work is discussed further on the University of Cambridge news pages and is published in The Cryosphere.

# Nimrod expedition sledging flag acquired for the nation

The Scott Polar Research Institute and the National Maritime Museum have acquired the sledging flag and sledge that Dr Eric Marshall (1879-1963) used on Ernest Shackleton's British Antarctic Expedition (BAE) of 1907-1909. The sledge and sledging flag are the two most recent acquisition supported by the National Heritage Memorial Fund, with a grant of £204,700.

The flag will rejoin its partner, Shackleton's sledging flag from the same expedition, in the collections of the Scott Polar Research Institute. It will be cared for in a temperature, humidity and light controlled environment so that it can be preserved for future generations. The Institute's Polar Museum hopes to update its displays relating to the Nimrod expedition to highlight not only the feat of almost reaching the geographic South Pole, but also the scientific goals and achievements of the expedition.

# Arctic Ocean sediments reveal permafrost thawing during past climate warming

Björn Eriksson

A new paper co-authored by Francesco Muschitiello has used seafloor sediments of the Arctic Ocean to understand how permafrost responds to climate warming and found evidence of past permafrost thawing during climate warming events at the end of the last ice age.

The study also shows for the first time that permafrost thawing occurred concomitantly with the release of large quantities of atmospheric CO2 as recorded in Antarctic ice cores. The findings suggest that Arctic warming by only a few degrees Celsius may be sufficient to disturb large areas covered by permafrost and potentially affect the Earth's climate system.

# Deep channels link ocean to vulnerable West Antarctic glacier

James Kirkham

Newly-discovered deep seabed channels beneath Thwaites Glacier in West Antarctica may be the pathway for warm ocean water to melt the underside of the ice.

Researchers from UK and US International Thwaites Glacier Collaboration, including James Kirkham from SPRI, collected data from offshore of the glacier during January-March 2019 aboard the icebreaker the RV Nathaniel B Palmer.

Exceptional sea-ice break up in early 2019 enabled the team to survey over 2000 square kilometres of sea floor right in front of the glacier — an area which had previously been hidden beneath part of the floating ice shelf extending from Thwaites Glacier.

The team's findings reveal that the sea floor contains deep channels leading under the ice shelf towards the grounding line which may provide pathways along which warm water can reach the underside of Thwaites Glacier, causing it to melt and contribute to global sea-level rise.

# Past subglacial water flow beneath the Antarctic Ice Sheet

James Kirkham

A new paper by James Kirkham, Julian Dowdeswell and others has used two decades of multibeam bathymetric data to explore the meltwater drainage imprint left by the Antarctic Ice Sheet in the past.

High-resolution maps of seabed areas previously covered by ice reveal over 2700 channels carved by subglacial rivers of meltwater flowing beneath the ice sheet.

The seafloor channels are extremely large (up to 3 km wide and over 200 m deep) and inform us about processes that are difficult to observe beneath the modern day ice sheet, and which occur over timescales much longer than covered by existing glaciological observations. The authors conclude that the channels were most likely incised by the periodic drainage of subglacial lakes over multiple glacial cycles.

# Lateral Meltwater Transfer Across an Antarctic Ice-Shelf

A new paper 'Lateral meltwater transfer across an Antarctic ice shelf', co-authored by Rebecca Dell, Ian Willis, Neil Arnold, Alison Banwell & Andrew Williamson, and published in The Cryosphere demonstrates methods to track surface meltwater across Antarctic ice shelves. The team developed a semi-automated method that allows them to track surface water bodies across Antarctic ice shelves, providing information on the area, volume, and geometry of water bodies throughout a melt-season. The method was applied to Nivlisen Ice Shelf in East Antarctica, and results revealed two large linear water bodies, which migrated towards the front of the ice shelf as the melt season progressed. https://tc.copernicus.org/articles/14/2313/2020/

# New study reveals Antarctic ice shelf retreat

A new study led by researchers from Scott Polar Research Institute, with colleagues from Loughborough University and the Geological Survey of Norway, calculates that ice shelves surrounding the Antarctic coast retreated at speeds of up to 50m per day at the end of the last Ice Age - a rate roughly 10 times faster than observed by satellites today.

Using drones, satellites and Autonomous Underwater Vehicles during the Weddell Sea Expedition 2019, our researchers were able to study ice conditions in the Weddell Sea in unprecedented detail. "By examining landforms on the seafloor, we were able to make determinations about how the ice behaved in the past," said Director of the Scott Polar Research Institute Professor Julian Dowdeswell, who was chief scientist on the expedition. "We knew these features were there, but we've never been able to examine them in such great detail before."

# New paper on subarctic treelines

A new paper, whose co-authors include Dr Gareth Rees, Dr Olga Tutubalina & Zuzana Swirad of the Scott Polar Research Institute, is now available as open access.

The paper, 'Is subarctic forest advance able to keep pace with climate change?' demonstrates that the still widespread assumption that treelines are moving northwards into the arctic tundra at a rate determined by climate change is wrong. The authors discuss that they are moving much more slowly than thought, and climate-change models must consequently be adapted accordingly.

# Vintage film reveals Antarctic glacier melting

Thwaites Glacier - Credit: NASA

Newly-digitised vintage film has doubled how far back scientists can peer into the history of underground ice in Antarctica, and revealed that an ice shelf on Thwaites Glacier in West Antarctica is being thawed by a warming ocean more quickly than previously thought. This finding contributes to predictions for sea-level rise that would impact coastal communities around the world.

Researchers digitised about 250,000 flight miles of Antarctic radar data originally captured on 35mm optical film between 1971 and 1979 as part of a collaboration between Stanford and the Scott Polar Research Institute (SPRI) at the University of Cambridge. The data has been released to an online public archive through Stanford Libraries, enabling other scientists to compare it with modern radar data in order to understand long-term changes in ice thickness, features within glaciers and baseline conditions over 40 years.

Professor Julian Dowdeswell, Director of the Scott Polar Research Institute, a co-author of the paper, commented: "These early records of ice thickness provide an important baseline against which we can measure the rate of change of the Antarctic Ice Sheet over the past 40 or so years. The high-resolution digitization of these records crucially makes them available for a series of important investigations on aspects of Antarctic environmental change."

# Reconstructing the past extent of Northern Hemisphere ice sheets

Dr Christine Batchelor and Professor Philip Gibbard of the Scott Polar Research Institute, together with researchers from the University of Cambridge's Department of Zoology, Durham University, University of Sussex, and Charles University in Prague, have published a paper in Nature Communications about the configuration of Northern Hemisphere ice sheets through the Quaternary.

In this study, the authors compile a synthesis of empirical data and numerical modelling results related to Northern Hemisphere ice sheets to produce new hypotheses regarding their extent at 17 time-slices that span the last 3.6 million years. These reconstructions, which are available as a series of maps and shapefiles of ice-sheet extent, illustrate significant variations in ice-marginal positions between glacial cycles.

# Origins of water beneath Mars' south polar ice cap

Dr Neil Arnold, in collaboration with Dr Matt Balme and Dr Frances Butcher (a former undergraduate in the Department of Geography here in Cambridge) of the Open University, and Dr Susan Conway of the University of Nantes, France, have published a paper in the Journal of Geophysical Research: Planets investigating the location of the recently-detected water layer beneath part of Mars' south polar ice cap.

Mars' present‐day ice deposits are generally assumed to be frozen throughout given its very cold climate, but new evidence from orbital radar data suggests a possible present‐day ~20km‐wide area of liquid water beneath Mars' south polar ice cap. Subglacial lakes are common on Earth, and their locations have been successfully predicted from ice surface topography and ice thickness using theories for subglacial water flow. This paper uses surface topography and ice thickness data for Mars' south polar ice cap to calculate the theoretical locations of possible subglacial lakes beneath the ice cap, and compares these with the location of the observed possible present‐day area of liquid water. The observed patch of possible liquid water does not coincide with the predicted lake locations however, which the paper interprets as implying that the liquid water is most likely to be an isolated patch of liquid, possibly caused by locally raised geothermal heating, rather than the liquid forming a "true", topographically constrained, subglacial lake.

# Past water flow beneath Pine Island and Thwaites glaciers

A team of researchers at the Scott Polar Research Institute along with collaborators at the British Antarctic Survey, Lamont‑Doherty Earth Observatory, and Victoria University of Wellington have published a paper investigating subglacial water flow beneath Pine Island and Thwaites glaciers in West Antarctica.

The study combines geomorphological mapping and numerical modelling of water flow beneath the West Antarctic Ice Sheet 20,000 years ago. The authors find that water discharged from a system of subglacial lakes carved out huge channels beneath the glaciers over several glacial cycles. The results are reported in the journal The Cryosphere.

The team includes PhD student James Kirkham, Professor Julian Dowdeswell, Dr Neil Arnold and Dr Kelly Hogan and Dr Robert Larter at the British Antarctic Survey.

# Rapid melting of the world’s largest ice shelf linked to solar heat in the ocean

A study conducted at the Scott Polar Research Institute links melting of the world's largest ice shelf to solar heating of the ocean surface. The findings may have important implications for the stability of ice shelf.

In a study of Antarctica's Ross Ice Shelf, which covers an area roughly the size of France, the team spent several years building up a record of how the north-west sector of this vast ice shelf interacts with the ocean beneath it. Their results, reported in the journal Nature Geoscience, show that the ice is melting much more rapidly than previously thought due to inflowing warm water.

# Glaciers and surface winds in a Himalayan valley

Emily Potter

PhD student, Emily Potter, with supervisors Ian Willis (SPRI), Andrew Orr (BAS) and colleagues have published their latest research in the Journal of Geophysical Research, which has also been featured as an Editors' Highlight in EOS.

The work uses field measurements and a regional climate model to determine the patterns and causes of wind acceleration around the Khumbu Valley, Nepal, and how they change over diurnal cycles, and between the monsoon and dry seasons.

It confirms strong daytime up-valley winds and weak nighttime winds in both seasons, and shows that pressure gradient forces are the dominant cause of wind acceleration, but that turbulence and advection are important too. The forcing terms are highly variable across the valley, and also strongly influenced by the presence of glaciers. When glaciers are removed from the model in the monsoon run, the wind continues much further up the valley, showing how local valley winds might respond to future glacier shrinkage.

This work will help the development of regional climate models in the Hindu-Kush Karakoram Himalaya, which are crucial for predicting future precipitation and glacier melt in the region.

A team of British and American researchers, co-led by Alison Banwell and Ian Willis at the Scott Polar Research Institute, has measured how much the McMurdo ice shelf in Antarctica flexes in response to the filling and draining of meltwater lakes on its surface. This type of flexing had been hypothesised before and simulated by computer models, but this is the first time the phenomenon has been measured in the field. The results are reported in the journal Nature Communications.

# Scientific expedition to the Larsen C Ice Shelf

A planned scientific expedition to the Antarctic to visit and study the Larsen C Ice Shelf - and explore the area where Endurance, Sir Ernest Shackleton's ship was last seen - will be led by Professor Julian Dowdeswell next year.

Professor Dowdeswell, Director of the Institute and Professor of Physical Geography, will lead the international Weddell Sea Expedition 2019 next spring. It will bring together leading researchers from the Institute as well as the Nekton Foundation, the University of Canterbury in New Zealand, the University of Cape Town and the Nelson Mandela University in Port Elizabeth, South Africa.

Speaking on BBC Radio 4's Today programme this morning, Professor Dowdeswell explained that the expedition will survey the underside of the iceshelf using underwater submersibles, to ascertain whether conditions leading to the calving of an enormous iceberg from Larsen C in 2017 means that the shelf may collapse: "Iceshelves butress the interior of the Antarctic icesheet, they effectively act to hold back the ice that flows from the interior of the Antarctic to the edge. They are in some senses vulnerable because not only can they lose mass by the production of icebergs at their edge but also because they're floating, beneath they have ocean water flowing in and that ocean water can lead to meltrates at the base of a number of metres per year and this is what's been happening to some areas of Antarctica."

# The Geological Anthropocene born in Burlington House

Geological Society, London

Discussions concerning the recognition and potential definition of a new division of geological time during which humans have become overarchingly influencing natural systems have led to the proposal to define a new time interval, the Anthropocene (see earlier reports on these pages).

The controversy generated in the geological world has been offset by the remarkable interest the concept has initiated in non-geological, and especially in non-scientific fields. The discussions, initiated during meetings of the Geological Society's Stratigraphy Commission, of which Professor Phil Gibbard, Dr Colin Summerhayes, and the other authors are members, has led to worldwide debate. These discussions have also spawned new lines of research, and encouraged inter-disciplinary discussions by members of the department, involving reseachers and students alike. A new report presents the state of these fast evolving discussions developments that have animated the normally tranquil world of stratigraphy.

# Rising Tides bring innovation prize

Eli Keene

Victoria Herrmann, a PhD student at the Scott Polar Research Institute and a Gates Cambridge Scholar, has won a prestigious US social entrepreneurship prize for a research project on US towns and cities at risk of partial submersion due to climate change.

Victoria's was one of 10 projects to scoop the JM Kaplan Fund Innovation Prize.

Her winning Rising Tides project will create a new online matchmaking platform that connects pro bono experts with climate-affected communities. Whether taking on archaeological work in Alaskan villages or oral histories in Mississippi's historic black communities, the project will seek to safeguard heritage by connecting national expertise to some of the 13 million Americans who stand to be displaced due to rising waters in the coming years. It will initially focus on bringing technical assistance directly to small and medium-sized towns that are geographically remote and socioeconomically vulnerable. By connecting communities with volunteer professionals looking to donate skills - from a one-hour consultation to a fully fledged cultural resources management plan - the project seeks to build social cohesion, preserve historic sites and empower local traditions to withstand climate threats.

It is thought that by the end of this century, at least 414 towns and cities across America will be partially underwater from sea-level rise and accelerating extreme storms. The Rising Tides project will draw on Victoria's experience of working with community champions from Alaska to American Samoa through her America's Eroding Edges project, a partnership with the National Trust for Historic Preservation.

The J.M. Kaplan Fund has provided catalytic funding for projects in their early stages of development in the form of grants. The Prize leverages this legacy of catalytic grant-making in the field of social innovation.

In addition to cash support of $150,000, paid out over three years, plus a $25,000 bank of funds for project expense, the Prize includes capacity-building counsel from experts in organisational development, board cultivation, media coaching and leadership training. The three areas considered for the US prize are the environment, heritage conservation and social justice.

The Fund says: "The J.M.K. Innovation Prize is awarded to projects or ideas that represent a game-changing answer to a clearly identified need; are innovative within the Fund's three funding areas; demonstrate the potential to develop an actionable pilot or prototype with Prize funding; and hold out the promise to benefit multiple individuals, communities, or sectors through a clearly articulated theory of change."

Earlier this year Victoria [2014], who won the 2017 Bill Gates Sr Award and is currently completing her PhD in Polar Studies, was named on this year's Forbes 30under30 list for Law & Policy.

# Living without the Dead: Loss and Redemption in a Jungle Cosmos

Living without the Dead: Loss and Redemption in a Jungle Cosmos is a new book by Piers Vitebsky.

Just one generation ago, the Sora tribe in India lived in a world populated by the spirits of their dead, who spoke to them through shamans in trance. Every day, they negotiated their wellbeing in heated arguments or in quiet reflections on their feelings of love, anger, and guilt. Today, young Sora are rejecting the worldview of their ancestors and switching their allegiance to warring sects of fundamentalist Christianity or Hinduism. Communion with ancestors is banned, sacred sites demolished, and female shamans replaced by male priests, as debate with the dead gives way to prayer to gods. For some, this shift means liberation from jungle spirits through literacy, employment, and democratic politics; others despair of being forgotten after death.

How can a society abandon one understanding of reality so suddenly and see the world in a totally different way? Over forty years, anthropologist Piers Vitebsky has shared the lives of shamans, pastors, ancestors, gods, policemen, missionaries, and alphabet worshippers, seeking explanations from social theory, psychoanalysis, and theology. Living without the Dead lays bare today's crisis of indigenous religions as historical reform brings new fulfillments—but also new torments and uncertainties. From the award-winning author of The Reindeer People, this is a heartbreaking story of the extinction of an irreplaceable world, even while new religious forms come into being.

# New paper in Nature - Seafloor ploughmarks left by icebergs record rapid West Antarctic ice retreat

Matthew Wise, Martin Jakobsson

Thousands of ploughmarks on the Antarctic seafloor, caused by icebergs which broke free from glaciers more than ten thousand years ago, show how part of the Antarctic Ice Sheet retreated rapidly at the end of the last ice age as its margins balanced precariously on sloping ground and became unstable. Today, as the global climate continues to warm, rapid and sustained retreat may be close to happening again, and could trigger runaway ice retreat into the interior of the continent, which in turn would cause sea levels to rise even faster than currently projected.

Matt Wise and Julian Dowdeswell from SPRI, together with scientists from the British Antarctic Survey and Stockholm University investigated imagery of the seafloor of Pine Island Bay, West Antarctica. They found that, as seas warmed at the end of the last ice age, Pine Island Glacier retreated to a point where its grounding line – the points where it enters the ocean and starts to float – was perched precariously at the end of a seaward-shallowing submarine slope. It has long been thought that glaciers in this configuration are unstable.

Break up of a floating 'ice shelf' in front of the glacier left tall ice 'cliffs' at its edge. The height of these cliffs made them unstable, triggering the release of thousands of icebergs into Pine Island Bay, and causing the glacier to retreat rapidly until its grounding line reached a restabilising point in shallower water.

Today, as warming waters caused by climate change flow underneath the floating ice shelves in Pine Island Bay, the Antarctic Ice Sheet is once again at risk of losing mass from rapidly retreating glaciers. Significantly, if ice retreat is triggered, there are no relatively shallow points in the ice sheet bed along the course of Pine Island and Thwaites glaciers to prevent possible runaway ice retreat into the interior of West Antarctica. The results are published in the journal Nature.

"Today, the Pine Island and Thwaites glaciers are grounded in a very precarious position, and major retreat may already be happening, caused primarily by warm waters melting from below the ice shelves that jut out from each glacier into the sea," said Matt Wise of Cambridge's Scott Polar Research Institute, and the study's first author. "If we remove these buttressing ice shelves, unstable ice thicknesses would cause the grounded West Antarctic Ice Sheet to retreat rapidly again in the future. Since there are no potential restabilising points further upstream to stop any retreat from extending deep into the West Antarctic hinterland, this could cause sea-levels to rise faster than previously projected."

Pine Island Glacier and the neighbouring Thwaites Glacier are responsible for nearly a third of total ice loss from the West Antarctic Ice Sheet, and this contribution has increased greatly over the past 25 years. In addition to basal melt, the two glaciers also lose ice by breaking off, or calving, icebergs into Pine Island Bay.

Today, the icebergs that break off from Pine Island and Thwaites glaciers are mostly large table-like blocks, which cause characteristic 'comb-like' ploughmarks as these large multi-keeled icebergs grind along the sea floor. By contrast, during the last ice age, hundreds of comparatively smaller icebergs broke free of the Antarctic Ice Sheet and drifted into Pine Island Bay. These smaller icebergs had a v-shaped structure like the keel of a ship, and left long and deep single scars in the sea floor.

High-resolution imaging techniques, used to investigate the shape and distribution of ploughmarks on the sea floor in Pine Island Bay, allowed the researchers to determine the relative size and drift direction of icebergs in the past. Their analysis showed that these smaller icebergs were released due to a process called marine ice-cliff instability (MICI). More than 12,000 years ago, Pine Island and Thwaites glaciers were grounded on top of a large wedge of sediment, and were buttressed by a floating ice shelf, making them relatively stable even though they rested below sea level.

Eventually, the floating ice shelf in front of the glaciers 'broke up', which caused them to retreat onto land sloping downward from the grounding lines to the interior of the ice sheet. This exposed tall ice 'cliffs' at their margin with an unstable height, and resulted in rapid retreat of the glaciers from marine ice cliff instability between 12,000 and 11,000 years ago. This occurred under climate conditions that were relatively similar to those of today.

Today, the two glaciers are getting ever closer to the point where they may become unstable, resulting once again in rapid ice retreat.

The research has been funded in part by the UK Natural Environment and Research Council (NERC).

A paper published this week in the Annals of Glaciology, by an international team including Alison Banwell and Ian Willis, identifies the causes of crack formation and propagation on the McMurdo Ice shelf, Antarctica, where they have recently been undertaking fieldwork. Eventually this rift will result in the calving of an iceberg from the ice shelf, through a similar process to that which enabled the large iceberg to break-off the Larsen C Ice Shelf, a few days ago. As the climate warms it is possible that such ice shelf calving events will become larger and more frequent.

# New Cambridge research tracks changes to supraglacial lakes on the Greenland Ice Sheet

wikicommons

A new paper by a team at the Scott Polar Research Institute presents a novel method for tracking changes to individual supraglacial lakes in West Greenland using MODIS satellite imagery. The method developed is a Fully Automated Supraglacial lake Tracking ("FAST") algorithm that tracks changes to individual lake areas and volumes over successive images. This builds on previous research by calculating supraglacial lake volumes as well as areas, and can be applied to large areas of the Greenland Ice Sheet. The FAST algorithm is being used in ongoing research into Greenland Ice Sheet hydrology. The team comprises PhD student Andrew Williamson, University Senior Lecturer Dr Neil Arnold, Leverhulme/Newton Trust Research Fellow Dr Alison Banwell, and University Senior Lecturer Dr Ian Willis.

# New book: Atlas of Submarine Glacial Landforms: Modern, Quaternary and Ancient

Professor of Physical Geography and Director of the Scott Polar Instititute, Julian Dowdeswell, has co-edited a new Atlas of Submarine Glacial Landforms.

The Atlas of Submarine Glacial Landforms presents a comprehensive series of contributions by leading researchers from many countries that describe, discuss and illustrate landforms on the high latitude, glacier-influenced seafloor. Included are submarine glacial landforms from modern, Quaternary and ancient glacimarine environments.

The development of high-resolution imaging technologies has allowed detailed sea-floor mapping at water depths of tens to thousands of metres across continental margins and 3-D seismic imagery enables buried landforms to be identified. The Atlas contains an extensive methods section detailing the techniques used to image and understand the seafloor.

The 183 contributions are organised by: a) individual landforms in 2-page contributions, b) assemblages of landforms in 4-page chapters, and c) whole fjord-shelf-slope systems in 8-page contributions.

The 640-page Atlas is published online in the Lyell Collection by the Geological Society of London as Memoir 46 and also as a hardback volume.

The Atlas was launched at the Geological Society in London on Monday 23rd January 2017.

# Event: Geography and neo-vitalism

Matthew Gandy and Michael Bravo are holding a half-day workshop on the theme of "Geography and neo-vitalism" on Wednesday 23rd November. The neo-vitalist turn in geography raises many interesting questions across the discipline including connections with the geo-humanities and new fields of interdisciplinary scholarship. In recent years the works of Henri Bergson, Hans Driesch, and other thinkers have gained influence in debates over non-human agency, post-human subjectivities, and new concepts of nature. In this workshop we wish to bring together staff and graduate students with an interest in contemporary theoretical
debates for this half-day event.

# Visions of the Great White South exhibition to open in London

In August 2016 "Visions of the Great White South", an exhibition to be held at Bonhams will reunite the iconic photography of Herbert Ponting with the evocative watercolours of Edward Wilson over a century after the two men first dreamt up their plan for a joint exhibition. The British Antarctic Expedition, better known by the name of its ship the Terra Nova, took place from 1910-1913. Captain Robert Falcon Scott appointed Dr Edward Wilson, a close friend and a fine watercolourist, as his chief scientist. He also invited camera artist Herbert Ponting to join the expedition as official photographer, in a bold move in an era when high quality photography required great skill and careful attention in ordinary circumstances, let alone in the extreme environment of the Antarctic. Both Wilson and Ponting captured expedition life as well as keeping a visual record of scientific phenomena that the crew were studying.

Alongside the historic artworks, visitors will have the opportunity to see contemporary interpretations of the 'great white south'. For several years the Friends of Scott Polar Research Institute, with the support of Bonhams and the Royal Navy, have run an artist in residence scheme which sends an artist to the Antarctic on board the icebreaker HMS Protector. Artists including Captain Scott's grand-daughter Daphila Scott and renowned wildlife artist Darren Rees will exhibit their responses to the frozen wilds of Antarctica.

# After the Iron curtain: Poor parenting and state intervention in cross cultural perspective: a one-day workshop

This workshop, on Wednesday June 10th 2015, is concerned with the issue of 'poor' parenting in cross-cultural perspective, and particularly a UK comparison with post-Soviet countries. Taken at face value, the concept of 'poor' parenting may look very different in countries with different political, ideological and socio-economic structures such as liberal democracies of the UK and the US, yet one study has revealed some (tentative) similarities in child welfare practices. This workshop problematizes the concept of 'poor' parenting by making it an analytical concept and placing it in a comparative context, asking three main questions: (1) What constitutes 'poor' parenting in a particular country? (2) What are the underlying concepts of childhood and parenthood this relies on? (3) What are the similarities in child welfare practices, and how do we account for these?

Why do scientists work in extreme environments, and is it worth the financial and human cost? A discussion at The British Library on 25th March 2015.

Scientists travel to the tops of mountains, the polar regions and even outer space in order to conduct experiments, make observations and set up instruments. What have we learned from doing science in extreme environments? Is what we gain worth the high financial, and sometimes human, cost? Does exploring these places also make science a vehicle through which geopolitics is played out? Do we need to explore for the sake of exploration? University of Cambridge geographer and historian of science Dr Michael Bravo joined a panel discussion chaired by science journalist Dr Gabrielle Walker, along with Director of the British Antarctic Survey Professor Jane Francis, UCL anaesthetist and space medicine expert Dr Kevin Fong.

# Captain Scott's treasurer commemorated: plaque to be unveiled to Sir Edgar Speyer

Captain Scott went down in history as a fearless explorer who faced death in the Antarctic with dignity and valour. But the man who helped bankroll his expeditions has for a century been dismissed as a German collaborator in World War I, suspected of signalling naval secrets to German submarines from his country-house on the Norfolk coast. Just over a century after Scott's final expedition, a memorial plaque to Sir Edgar Speyer (1862-1932) is to be unveiled this autumn at the Scott Polar Research Institute at the University of Cambridge.

# New study finds Greenland Ice Sheet more vulnerable to climate change

Sam Doyle

Research by Dr. Marion Bougamont and Dr. Poul Christoffersen at the Scott Polar Research Institute shows that the massive ice sheet covering most of Greenland is more vulnerable to climate change than earlier estimates have suggested. In addition to assessing the impact of increased levels of surface melting on ice flow, the new research also takes into account the role that soft, spongy ground beneath the ice sheet plays in its changing dynamics. The study concludes that there is a limit on how much water can be stored in the soft ground beneath the Greenland Ice Sheet, and this makes it sensitive to climate change as well as to increased frequency of short-lived, but extreme, meteorological events including rainfall and heat waves. The findings are published 29 September in the journal Nature Communications.

# Pan-Inuit Trails Atlas Launched at SPRI

Michael Bravo

A new digital resource brings together centuries of cultural knowledge for the first time, showing that networks of trails over snow and sea ice, seemingly unconnected to the untrained eye, in fact span a continent – and that the Inuit have long-occupied one of the most resource-rich and contested areas on the planet. The material has been digitised and organised geospatially, with trails mapped out over satellite imagery using global positioning systems. It constitutes the first attempt to map the ancient hubs and networks that have long-existed in a part of the world frequently and wrongly depicted as 'empty': as though an unclaimed stretch of vacant space.

"To the untutored eye, these trails may seem arbitrary and indistinguishable from surrounding landscapes. But for Inuit, the subtle features and contours are etched into their narratives and story-telling traditions with extraordinary precision," said Dr Michael Bravo from the Scott Polar Research Institute, part of the Department of Geography. "This atlas is a first step in making visible some of the most important tracks and trails spanning the North American continent from one end to the other. Essentially the trails and the atlas reduce the topology of the Arctic, revealing it to be a smaller, richer, and more intimate world."

# Lakes discovered beneath the Greenland Ice Sheet using radar

This study, published in Geophysical Research Letters, reports the discovery using airborne radar of two subglacial lakes 800 metres below the surface of the Greenland Ice Sheet. The two lakes are each roughly 8 to 10 square-kilometres in area, and at one point may have been up to three times larger than their current size.

Subglacial lakes are likely to influence the flow of the ice sheet which, in turn, impacts global sea-level change. The discovery of the lakes in Greenland will help researchers to understand how the ice will respond to changing environmental conditions.

The work was undertaken by Steve Palmer, Julian Dowdeswell, Poul Christoffersen and Toby Benham at the Institute, in collaboration with colleagues at the universities of Texas and Bristol.
