Rivers on ice: understanding meltwater pathways on mountain glaciers A new study led by Holly Wytiahlowsky of the Durham Glaciology Group has just been published, providing insight into glacier hydrology by producing the first inventory of supraglacial channels on m…

@hollywytia.bsky.social has written a short, public-friendly blog post about her new paper in the Cryosphere about supraglacial (ice-surface) streams on Swiss glaciers. Learn more at the link below πŸ‘‡

A few of my recent creations from the office bake-off: the Antarcticake and my finale entry, β€˜rake-off’. Happy to have placed first! Will be putting the winnings to good use and buying everyone extra nice Christmas presents this year.

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...

🚨 Interested in the form and variability of the supraglacial hydrological system? @hollywytia.bsky.social et al. explore the controls on channel distribution and characteristics on Swiss Alpine glaciers in a new paper hot off the press at The Cryosphere! ❄️ tc.copernicus.org/articles/19/...

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 πŸ¦†!

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! 🌊

Worst situation of glaciers in Central Asia ever... πŸ₯΅

Shown here is Grigoriev ice cap (4600 m asl, Kirghizistan)

Not a single snow patch left up to the summits, for the first time in over 10 years! 😱

Another great day of the IGS symposium, with a field trip visiting evidence of glaciation in upper Teesdale, Eden Valley drumlins at Brough Castle, the fluvioglacial landscape of the Brampton Kame Belt, and streamlined bedforms from Tyne Gap ice streaming (plus Roman archaeology) at Hadrian's Wall!

Nested glacier surges! This is Liestolbreen in Svalbard, surging into Nathorstbreen (which itself surged from 2008), and then being surged into by Doktorbreen. All brought to you by the magic of Sentinel-1 SAR

SPEECHLESS BEFORE / AFTER #BLATTEN

The magnitude of destruction after the 3:24 pm collapse of Birch Glacier is immense! 😱

All the forest has been razed and the ice/wood/debris dammed the Lonza river 🌊

Some buildings of Blatten are buried 🏠
