Exciting 24-month Postdoc opportunity for a peatland palaeoecologist, working with Dr Jenna Sutherland at Leeds Beckett U. on the NERC-funded InSPIRE project. Investigating initiation of new peatlands in deglaciating parts of Alaska, including fieldwork vacancies.leedsbeckett.ac.uk/ce0984li_web...

So permafrost peatlands burn and they release lots of CO2 through combustion - but that's just the start. Christopher Schulze shows in a new GRL study that slow recovery causes continued CO2 losses in the following decade - overall similar in magnitude to the combustion! doi.org/10.1029/2025...

New Study in ES&T! Permafrost peatlands accumulate mercury from distant sources, but thaw causes collapse into wetter bogs and fens. Lauren Thompson shows that these bogs, and especially fens, become hotspots for mercury methylation, and potential downstream transport. pubs.acs.org/doi/10.1021/...

New study where McKenzie Kuhn, I and co-authors show that accounting for differences among wetland and lake types is crucial for estimating current and future boreal-Arctic methane emissions – out now in Nature Climate Change. www.nature.com/articles/s41...

Perfect day for measuring carbon dioxide and methane emissions from our thawed (former permafrost) fen in northern Alberta. 20 deg C, light breeze and almost no mosquitoes.

The term “abrupt permafrost thaw” is increasingly used in the scientific literature. The concept comes with challenges as authors look at “abrupt“ change with different perspectives on time scales, magnitudes, and impacts. Webb et al developed a new conceptual framework: doi.org/10.1007/s406...

I spent this week collecting river samples in northwestern Canada (Dehcho, Hay, and South Slave regions), an area the size of England with ~4,000 km of driving. And so much of the landscape is burned - we drove hours and hours through charred forests. The last decade has been unprecedented.

The bog gives and the bog takes. Liam Heffernan's PhD site, the Lutose thermokarst big - photos from 2015 and today 10 years later... Note the trees dying in the background due to permafrost thaw, and the growth of Sphagnum mosses covering our once proud boardwalk!

I have a fully funded PhD position open for start in Jan or May 2026. Field work in peatlands of the Northwest Territories, with lab work to understand potential downstream mobilization of carbon, nutrients, mercury after thaw or wildfire. Reach out for more information, and please send on!

When the Arctic burns, the soils thaw. How much and for how long? Anna Talucci compiled depth of thaw measurements from 157 sites, now published in ESSD. Main impact occurs 4-10 years after fire, but effects remain 20+ years. Key information to estimate losses of soil C! doi.org/10.5194/essd...

'We should restore peatlands to slow down the invading Russians' as an idea tells us a lot about the state we are in. www.aeco.earth/blog/peatlan...

My perspective “Tree methane exchange in a changing world” is now out in @natrevearthenviron.nature.com rdcu.be/erF4j

This new map provides a global view of the distribution of a multitude of aquatic ecosystems, including various wetlands. It's a pretty big step forward, and I look forward to seeing how it will be used e.g. to study wetland greenhouse gases. essd.copernicus.org/articles/17/...

We're new here! Help us connect with our members and interested followers 😀

I run a mid-size research group (7 graduate students / staff, 3 field assistants) which focuses on field-based research in northern Canada. Last year (2024-2025) our total expenses were ~CAD$370,000, provided in grants from federal/provincial/industry agencies, and it was spent as shown below.

JOB ALERT Exciting opportunity for a Lecturer (equivalent to Assistant Professor) in #PhysicalGeography specialising in #peatland science to join our #Geography department at @uniofmanchester.bsky.social. Full details for the job can be found here: www.jobs.manchester.ac.uk/Job/JobDetai...

For more on carbon loss from thawing permafrost peatlands, see our NWT paper here: onlinelibrary.wiley.com/doi/10.1111/...

Great short summary video of #permafrost! Not mentioned in the video... permafrost also includes peat in northern regions, incl. Canada. These are two small cores of ice-rich permafrost peat in Yukon. Placed on a pillow of fluffy Sphagnum moss for the photo 😀

Winter field work at a thermokarst fen in northern Alberta by PhD student Finn Kurylowicz this week - chilly but very successful. The first winter for the eddy covariance set-up and it had collected data on almost all days since late November.

This resonates with me - and I've seen this happen quickly. Fewer field trips for classes I teach (due to budgets and increased bureaucracy to make them happen) and for field research (more attention to field safety - good! - but more bureaucracy forces less ambitious plans).

There's a postdoc in peatland biogeochemistry advertised on our project by Dolly Kothawala and Gustaf Granath at Uppsala University. I can highly recommend Uppsala as a place to live and work. www.uu.se/en/about-uu/...

We are looking for a grant-funded doctoral resarcher on a project focusing on how tree and shrub expansion into the tundra impact biodiversity and carbon balance @Department of Geosciences and Geography @helsinkiuni.bsky.social! DM me if you are interested, and please share!

One of my favorite things about #peatlands is their patterning at different scales caused by millennia of interplay between hydrology and peat accumulation - mainly Sphagnum mosses. Spent my Saturday evening looking at satellite images of the Hudson Bay Lowlands - a perfectly reasonable activity…

Congratulations to Weiwei Wang (early career researcher) on her paper in Science out today - 'Canadian forests are more conducive to high-severity fires in recent decades' largely due to increases in fuel aridity. www.science.org/doi/10.1126/...

“It is the first time that we’re seeing this shift at such a large scale, cumulatively across all of the tundra. That’s a pretty big deal,” Sue Natali, a co-author and lead researcher on the study at @woodwellclimate.bsky.social told @theguardian.com www.theguardian.com/environment/...

I'm hiring, two fully funded PhD positions! Come work in Umeå in Arctic Sweden, a leading place for high-latitude ecosystem ecology and carbon biogeochemistry

First lecture of the semester, and a new course on Water Resource Management. Most of my winter "break" was used to prepare for the course. What are your best examples of Canadian water resource management issues that I should highlight?

No doubt an important paper by @goldenwater.bsky.social and others. Headwater systems are a critical interface between groundwater, surface water and the landscape, and the source for downstream waters. Need to continue advancing sci & mgmt of these systems! www.nature.com/articles/s44...

I'll be dammed! Next week Jessica Lagroix will present her MSc thesis on the influence of beaver ponds on water chemistry on the Taiga Plains, focusing on methylmercury. Two years of sampling, bushwacking to access sites and avoiding wildfires, but results are really cool TBA! #FieldworkFriday

Well done Edmonton - 7.30 am and last night's snow has been cleared from the bike path. Much appreciated!

I presented my #AGU24 talk this morning and wanted to summarize my take homes. 20 yrs ago I created the Alaska Peatland Experiment (APEX) to experimentally push hydrology into wetter and drier modes. CO2 emissions are remarkable stable while CH4 is very high with flooding. 1/

I am soon recruiting two PhDs and a postdoc, to work on carbon, methane, metabolism in arctic stream networks. Glad to chat potential opportunities during #AGU24 @agu.org ! There is also soon another postdoc position on oxygen responses to peatland restoration with @ryansponseller.bsky.social ⬇️

New truck for the CAWS research group - last truck lasted 7 years and we put 350,000 km on it. Will this one go further? What podcasts will be popular? Who will get it stuck on a muddy road? Also - infrastructure grants are slow, I budgeted for this truck in 2019 so needless to say I blew my budget!

Very nice review - a must read for students working on understanding temporal patterns in river water chemistry! Cheers

For #FieldworkFriday I'm today reminiscing about a 2018 trip with McKenzie Kuhn (UBC) sampling greenhouse gas emissions from peatland ponds near Fort McPherson in northernmost Canada. It's a 3,500 km one-way drive from Edmonton (well worth the drive!). Note the permafrost thaw along pond edges!

Global mapping suggests that agriculture is the biggest source of peatland loss in Canada, but what do we really know about the area and potential GHG emissions? New review paper with Kelly Bona, Ph.D. and Chang Liang wires.onlinelibrary.wiley.com/share/EJN7C6...

For #FieldworkFriday we're heading to northernmost Alberta and the Hay-Zama wetland, on Dene Tha' traditional lands. Our group is not all about peat, here Sarah and Fiona opportunistically took soil samples across the 35 x 20 km wetland basin during extreme drought to assess soil carbon storage.

Pancake ice forming on the North Saskatchewan River in Edmonton today. Also - I changed to studded tires on my bike for the commute, which was good timing.

The Hay River in northwestern Canada (with Alexandra Falls in the pictures) is at the center of my groups' research. How will permafrost thaw, wildfires, warming, and droughts affect the mobilization of carbon, nutrients, and mercury from the widespread peatlands in its watershed?
