Distribution and characteristics of supraglacial channels on mountain glaciers in Valais, Switzerland
Abstract. Supraglacial channels form a key component of glacier hydrology, transporting surface meltwater to englacial and proglacial positions, which impacts ice flow dynamics, surface mass balance a...

Wonderful week spent with @geogdurham.bsky.social
students on the Arctic fieldtrip learning about Arctic environments, governance, and politics. Great enthusiasm all around! Students even led some roadside yoga and rounders when the bus broke down. Some pretty good northern lights too!

Had a lovely time at the @igsoc.bsky.social British Branch meeting in Oxford! Great to catch up with familiar faces and meet some new ones too. It was also nice to have received commendations for my talk and left with a new duck companion 🦆!

Endless debris flows...😱
These images of the debris flow that hit Bionaz (1600m, Valpelline) last night show why you should avoid rivers and streams during heavy thunderstorms in the mountains! 🌊
