[Sarah Elise Sapper @SarahSapper]

Jan 21st marks the official start of the @UN International Year of Glaciers' Preservation 🏔️❤️‍🩹 #Glacier2025 chaired by @UNESCO and @WMO. I am delighted to be speaking at the side event hosted by the @iaeaorg on the use of isotopes in glaciology.

[IAEA NA @IAEANA]

As we officially launch the Intl. Year of Glaciers' Preservation, join us as we discuss how nuclear tech can help protect glaciers, helping assess downstream water availability & understand the sustainability of water resources

The Cryosphere Pavilion will host more than 60 side events over the next two weeks.

On Nov. 11, our team of Early Career Scientists (all PhD and postdoctoral level) will introduce themselves and share their research.

Join in person or watch virtually! ❄️

"We are seeing changes across all aspects of the cryosphere, including glaciers, permafrost, and snow."

From high mountain glaciers to meltwater flowing in the darkness beneath polar ice sheets, four young researchers explained why ambitious climate action is needed today #COP29

Have you checked out our Most Read Article in the past year yet? It's @SarahSapper et al’s study of subglacial meltwaters of 3 outlet glaciers from the St. Elias Mountains in Yukon, Canada that discovered all 3 as subglacial CH4-emitting sites: https://t.co/wVz4H8pvbH

[Sarah Elise Sapper @SarahSapper]

Well this is cool news 🥳. Thank you all for having a read! There is more exciting research on subglacial methane emissions in the working! 🧐

A jökulhlaup captured by automatic camera at Isunnguata Sermia, West Greenland - 2 October, 2023. Probably caused the the drainage of a proglacial lake on the north side of the outlet glacier. This is well after surface melt has ceased.

It's that time of the year again! #EGU24. Who else is in Vienna? You can find me on Wed from 10.45-12.30 at Poster spot X1.58 or the rest of the week first in line for a coffee. Come say hello! 😊🙋🏻‍♀️

This is a short summary in easy language of my recently published paper about methane emissions from the meltwater of 3 mountain glaciers in Yukon, Canada.

Global melting is prying the lid off methane stocks, the extent of which we do not know 👉 https://t.co/iUvuFcWmf8

Methane discovery in Yukon glaciers: "Much more widespread than we thought" - @SarahSapper

[SCIENCE - KU @science_ku]

Global melting is prying the lid off methane stocks with unknown extent. @SarahSapper has discovered high concentrations of the powerful greenhouse gas in meltwater from three Canadian mountain glaciers, where it was not thought to exist: https://t.co/39eXo6GYML #climate #methane

#MeltingGlaciers are the new cows🐄! Meltwaters of Dusty, Kluane & Donjek glaciers, 3 alpine glaciers in Yukon's St. Elias Mountains, are a source of #methane with concentrations up to 250 times⬆️than in the atmosphere!😱 Just out➡️

[Sarah Elise Sapper @SarahSapper]

And how are the size of the glacier, the bedrock geology, and the surging history linked to the CH4 concentrations in the meltwater? These are further questions we are discussing in the paper.
Spoiler: the size doesn’t matter 😉

[Sarah Elise Sapper @SarahSapper]

Next, we wanted to know where the CH4 comes from. For this, we sampled dissolved CH4 for analyses of its stable carbon (13C) and hydrogen (2H) isotopes by our colleagues (@FrankKep from @Geow_UniHD). Their measurements revealed that the CH4 has both a biotic and abiotic source 👏
