Welcome on bluesky Janani!

I’m gonna miss the Permafrost Terminology Action Group of the Canadian Permafrost Association. Most of us made it to GeoManitoba 2025 for the Glossary launch and photo op 🙌 #scicomm

A glacier partially collapsed in Switzerland, burying the village of Blatten in a huge landslide of ice, rock, and mud after residents had been evacuated.

Scientists called the collapse of the glacier “unprecedented” in the Swiss Alps.

Mark your calendars! On May 5th, we honor and remember our missing and murdered Indigenous relatives. Too many voices silenced, too many families still waiting for justice. #MMIP #MMIW #MMIWG2S #May5 #NeverForgotten

What a great initiative. It's so important to hear the stories of silenced scientists. 🧪 ⚛️ 👩‍🔬

The soil of permafrost regions, which contains a lot of organic carbon may thus also represent a large reservoir of mercury. We've been wondering how permafrost thaw and post-thaw ecosystem evolution may affect net methylmercury production.

the soil Hg at the site is not from local contamination, it is mercury from natural (eg forest fires) and athropogenic (eg coal combustion) sources that was atmospherically deposited on the surface, bound to vegetation and organic matter, and finds itself stored in the soil over time.

ha, that site has been on my to do list as well, would be happy to join efforts.

Mercure et pergélisol: le problème pourrait avoir été surestimé L'abondance de ce métal dans le pergélisol et la production de son dérivé neurotoxique en raison du réchauffement climatique seraient moins importantes que prévu dans certaines régions nordiques

Graphical abstract in 3 panes depicting a lithalsa, a thaw pond, and a revegetated depression. It indicates that the proportion of mercury that is methylated in near surface sediment was 0.57% on the lithalsa, increased to 6.9% in yound thaw ponds, decreased to 4.8% when Carex spp where widespread in the pond, and to 2.6% when Sphagnum spp. established in the depression.

Bravo Brendan, this is awesome!

not anymore (10 years in Yukon but South of arctic circle, now in south for over 15 years). No sweat, I'm happy there is a space for the voices of Arctic Residents. 👍

Tuk lakes, my thermokarst Valentine

Hi Brendan, where is this? It looks like an ancient drained thermokarst lake basin.

This has been in the works for a while, and is not a response to recent events, but the timing couldn't be better: Canada now allows foreign students and postdocs to apply for more doctoral and postdoctoral fellowships! www.nserc-crsng.gc.ca/NewsDetail-D...

I'd like to join the list too (permafrost scientist)

Ah, Merci Brendan for the warm welcome! Very excited to discover the permafrost, geomorphology, and northern conversation on Bluesky!
