I'm working with Dr Duncan Quincey (University of Leeds), Dr Tris Irvine-Fynn (Aberystwyth University) and Miss Morgan Gibson (PhD student at Aberystwyth University) to investigate how glacier volumes vary over time and to measure how influential the Indian monsoon is relative to Northern Hemisphere climate variations. Our field site is the highest glacier in the world—the iconic Khumbu Glacier in Nepal, a 20-km glacier flowing from the southern slopes of Mt. Everest.

Observations of large, high-altitude Himalayan glaciers are scarce, which makes understanding their behaviour in the future very difficult. The lack of data is mostly due to the remote location of these glaciers, but after our first field season at Khumbu Glacier I would add that the 10-day trek to get there, horrible altitude sickness, being woken up by hungry yaks at 5am, monsoon snow, and the sheer exhaustion of spending every day working on a debris-covered glacier at 5000 m above sea level may also have something to do with it!
Despite the challenges of working in such an extreme environment, we had a successful and enjoyable field season and are now busy working on writing up the first set of results. Myself and Morgan are looking forward to returning to the Khumbu in November to collect more data after the summer monsoon has ended. I'll be sure to update you on our adventures once im back but you can follow us live via our Twitter account @KhumbuGlacier.
