Scientists to Drill Through World's Highest Glacier Near Mount Everest
Climate change scientists are heading to the Himalayas in a bid to become the first team to successfully drill through the world's highest glacier located in the foothills of Mount Everest.
London: Climate change scientists are heading to the Himalayas in a bid to become the first team to successfully drill through the world's highest glacier located in the foothills of Mount Everest.
An international research team will spend up to six weeks working at an altitude of more than 5,000 metres on the Khumbu glacier in Nepal and will be using a specially adapted car wash unit to drill up to 200 metres into the ice.
Once the drilling has been completed, the team, led by Duncan Quincey from University of Leeds in the UK, will be able to study the glacier's internal structure, measure its temperature, how quickly it flows and how water drains through it.
"All the current data collected on these glaciers only just scratches the surface," Quincey said.
Glacier melt-water from across the Himalayan range supports the livelihoods of around 40 per cent of the world's population, researchers said.
However, dams and lakes that form on the glacier present a significant risk of flash flooding for people living down-stream.
"This is a real risk in the Himalayas as it is in other regions such as the Andes, and has the potential to endanger the lives of thousands of people," said Hubbard.
Located in north-eastern Nepal, the 17 kilometre-long Khumbu glacier is often used by climbers on their way to Everest base-camp and flows from an altitude of 7,600 metres.
The team will be working at an altitude of over 5,000 metres and will have to contend with a number of physical and technical challenges.
Equipment weighing about 1,500kg will need to be transported to the drill site on the glacier.
Half the equipment will be airlifted by helicopter and half will be carried up by locally-hired Sherpa, yaks and the research team.
The team will travel to the Khumbu glacier in the foothills of Mount Everest this month. It will be the first of two trips. The team is set to return for a second nine week expedition next year.
