The team worked at an altitude of 5,000m (16,400ft), in their quest to find out how climate change affects Khumbu. The 10mi (17km) long glacier, in north-eastern Nepal, flows from as high as 7,600m (25,000ft) down to 4,900m (16,000ft) and is often used by climbers on their way to Everest base camp. Half of the EverDrill team's 1,500kg (236st) equipment was airlifted onto the glacier by helicopter in several trips, while the other half was guided by Sherpas and yaks.

 

According to the project leader Prof Bryn Hubbard: "Working in the field is challenging at best, but this mission presented some particular challenges. We didn't know how well our equipment will perform at altitude; let alone how we will be able to contend with the thin air." 

 

Robertson Geologging stated that it is proud of the performance of its technology on this important mission, tasked to develop a better understanding of what happens in glaciers in response to climate change. The company's extensive history of design and performance testing expertise, backed by its ISO-compliant manufacturing processes deliver logging systems that are capable of surviving the rugged conditions encountered in such crucial research projects.
