# Subglacial lakes discovered under Devon Island ice cap

Professor Julian Dowdeswell

A new study of the Devon Island ice cap, led by a team from the University of Alberta, has discovered two subglacial bodies of water. These are the first subglacial lakes to be observed in the Canadian Arctic, and are estimated to cover areas of five and eight square kilometres respectively.

The findings, co-authored by Director of The Scott Polar Research Institute Professor Julian Dowdeswell, have been published in Science Advances

# 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."

Further coverage also features on BBC News, Telegraph and Independent websites.

# Chain reaction of fast-draining lakes poses new risk for Greenland ice sheet

Timo Lieber

A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability.

Researchers from the SPRI and others across the UK, Norway, US and Sweden have used a combination of 3D computer modelling and real-world observations to show the previously unknown, yet profound dynamic consequences tied to a growing number of lakes forming on the Greenland ice sheet.

# New paper: Controls on rapid supraglacial lake drainage in West Greenland

Andrew Williamson

A team of researchers from the Scott Polar Research Institute have published a new paper investigating the causes of rapid lake-drainage events on the Greenland Ice Sheet. For this, the research team assembled a variety of different remotely sensed datasets to derive a series of controls that might explain why some lakes drain rapidly and others do not. However, among the controls investigated, they were unable to find any statistically significant drivers of the lake-drainage process.

The team includes PhD student Andrew Williamson, Dr Ian Willis, Dr Neil Arnold and Dr Alison Banwell.

# SPRI MPhil Scholarships

Sir Cam

The deadline for the Debenham Scholarship and the Scott Polar Scholarship is 31 March 2018. Each scholarship is worth £7,614 (2018-19 rate) and will be awarded to the best applicant for the M.Phil. in Polar Studies who is not in receipt of another University award. By applying for the M.Phil. in Polar Studies, you will automatically be entered into the competition for these awards, as long as your application is received by the deadline.
