Welcome on bluesky Janani!

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.

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.

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!
