Image of the Week – We walked the Talk to Everest

The 12 day “Walk the Talk” Field Conference and Community Consultation through Sagarmatha National Park, Nepal, discussed a wide range of research outputs with local communities, tourists, and officials. Topics covered glaciers, mountains, environmental and landscape change, Sherpa livelihoods, tourism, and natural hazards. The conference, organised by Himalayan Research Expeditions, was the first ...[Read More]

Image of the Week – Climbing Everest and highlighting science in the mountains

Dr Melanie Windridge, a physicist and mountaineer, successfully summited Mount Everest earlier this year and has been working on an outreach programme to encourage young people’s interest in science and technology. Read about her summit climb, extreme temperatures, and the science supporting high-altitude mountaineering in our Image of the Week. It’s bigger than it looks! Experiencing the majesty ...[Read More]

Image of the Week – Making waves: assessing supraglacial water storage for debris-covered glaciers

A creeping flux of ice descends Everest, creating the dynamic environment of Khumbu Glacier. Ice and snow tumble, debris slumps, ice cliffs melt, englacial cavities collapse, ponds form and drain, all responding to a variable energy balance. Indeed, Khumbu Glacier is a debris-covered glacier, meaning it features a layer of sediment, rocks and house-sized boulders that covers the ice beneath. Recen ...[Read More]

Image of the Week – Drilling into a Himalayan glacier

How water travels through and beneath the interior of debris-covered glaciers is poorly understood, partly because it can be difficult to access these glaciers at all, never mind explore their interiors. In this Image of the Week, find out how these aspects can be investigated by drilling holes all the way through the ice… Hydrological features of debris-covered glaciers Debris-covered glaciers ca ...[Read More]

Image of the Week – Far-reaching implications of Everest’s thinning glaciers

From 1984 to 2015, approximately 71,000 Olympic size swimming pools worth of water were released from the melting Khumbu Glacier in Nepal, which is home to Everest Basecamp. Find out how Himalayan glaciers are changing and the implications for downstream communities in this Image of the Week. Himalayan glaciers supply freshwater Himalayan glaciers supply meltwater for ~800 million people, includin ...[Read More]

Image of the Week – Supraglacial debris variations in space and time!

Image of the Week – Supraglacial debris variations in space and time!

There is still a huge amount we don’t know about how glaciers respond to climate change. One of the most challenging areas is determining the response of debris-covered glaciers. Previously, we have reported on a number of fieldwork expeditions to debris-covered glaciers but with this Image of The Week we want to show you another way to investigate these complex glaciers – numerical modelling! Deb ...[Read More]

Fieldwork at 5,000 meters in altitude

Fieldwork at 5,000 meters in altitude

Imja Lake is one of the largest glacial lakes in the Nepal Himalaya and has received a great deal of attention in the last couple decades due to the potential for a glacial lake outburst flood. In response to these concerns, the UNDP has funded a project that is currently lowering the level of the lake by 3 m to reduce the flood hazard. The aim of our research efforts is to understand how quickly ...[Read More]
