Dr Markland was the heartbeat of Friday’s @coffeeoutside.bsky.social in Edmonton. Here’s a few of my favorite photos from over the years. You made us all better humans for knowing you. RIP

Also currently in (sunny?!) St. Andrews Scotland learning the mysteries of volcanic sulphur isotopes from ice cores with @oceanicandrea.bsky.social and the tephra crew. I want to thank @uniofstandrews.bsky.social and their amazing Global Fellowship scheme for making this opportunity possible. 🌋

Have been laying low, but wanting do something light hearted, I will start sharing my summer for #fieldworkFriday. In May I joined the @iavcei.bsky.social @volc-ice.bsky.social field trip in Iceland. Stunning sunny days the entire time, so I can’t go back 🤣. Ready for future field work in NW BC! ⚒️🧪

The most disturbing thing for me in this video are all the people with cameras that run and swarm around this women as she is knocked to the ground by the agent. It looks like a feeding frenzy out in the ocean. Just angling to get a better view of the abuse. This world is cooked.

That was exactly what I needed today.

Behold, the #MinCup35 bracket! Use it to follow along, plan campaigns to support your favs, or make predictions on how voting will shake out. We start at the top left on September 1st, then alternate left and right as we work our way down.

I wrote something for @theglobeandmail.com www.theglobeandmail.com/opinion/arti... #yycbike #yegbike #BikeTO #BikeHFX

This paper by Meredith et al. (2025) examines global city exposure to volcanic hazards, using metrics such as population and distance to GVP Holocene volcanoes to quantify and rank cities at risk. This data has also been visualised through a web app. nhess.copernicus.org/articles/25/...

Check out our new paper about carbon, productivity and climate over 15,800 years in central Alaska. Out in @aaarjournal.bsky.social this paper pairs new sediment records from Eight Mile Lake with soil cores from the adjacent hillslope. www.tandfonline.com/doi/full/10....

After volcanic ash, loess, my second favourite sediment that falls out of the sky. It is great. Too many words to explain why here, it is a more in person over beer thing anyway.

This is so cool! Can’t wait to get up there next week. Go Yukon Go!

Un beau résumé des travaux de recherche de mon étudiante Élodie, co-supervisée par @tephrabird.bsky.social - Élodie fait un travail minutieux d'enquête pour trouver des traces d'éruptions volcaniques passées dans les tourbières de la vallée du St-Laurent 🌋🔬🧪

Yay! Super exciting. The only part that is amazing is waiting until 2029.

Check it out, avoid the for-profits! Help build up these journals. CJES has a long and proud history.

The Beringia Interpretive Centre was amazing to work with on some of the new displays they generously invited me to collaborate on. They accomplished so much with relatively few resources and it looks amazing! I still haven’t seen this though and won’t, so will have to take Brent at his word. 😬 🧪

When you turn on a light only to discover a rattlesnake, turning off the light doesn't make the snake disappear. It just means you can no longer see the snake. Feels like that's what's happening with all the weather and climate monitoring tools that we're losing, with SSMIS as the latest casualty.

Familiar sounding to this Albertan (Alison Redford). Although I doubt there will be accountability now (Danielle Smith). Also, 5 cars? Does he drive to work in a phalanx with his executive assistants? Or take UBER home to drive the next one the following morning? So tired of awful people. ☹️

How could you not be tempted by this no matter what your current employment looks like (i.e., I want to apply)? ⚒️🧪

The first time I was in this shelter under a Kyiv hotel - 1,215 days ago - messages came flooding in from well-wishers shocked missiles were being fired at a major city in 2022. Three years on, we’re all too used to it - in Kyiv, Tel Aviv, Beirut and Tehran. I truly hope it’s not your city next.

In my office on a beautiful June day, itching to get out. Universe intervened, my playlist picked Casimir Pulaski Day by Stufan Stevens. Cancer is a blight I have seen too many times. Now a friend faces losing his dad. It is one of his most beautiful songs (religious or not). Time to go and garden!

It was fun having you and Élodie in the lab! Quebec cryptotephra will soon be on the map for the first time. Next time I am coming to Montreal though 😉

May 18th 1980. Mount St. Helens is, in my opinion, one of the most amazing volcanoes in the US. This eruption was both tragic and scientific gift, an inspiration to many to learn more. Me included. I love going to visit her, with my geology friends, as she still has many stories to tell us. 🌋🧪⚒️

In Edmonton at this time of year entire parts of the city smell wonderful because of the lilacs, and the mayday trees too.

Let's talk about these two department store owners: brother and sister Louis Bamberger and Caroline Bamberger Fuld. From Newark, New Jersey. They are random people, basically. But in the late 1920s, with fascism taking over Europe, they made a choice that profoundly changed the world: 🧵

Remember the Avro Arrow? Well, that. But a car.

Oh! If you happen to live near Vancouver Washington, go! The people who work there are the best. And the monitoring rooms are pretty darned cool. 🌋🧪

Brutal. I use these to update my lectures every year for multiple classes. Such an incredible resource for education beyond all the other important aspects of NSIDC. Destructive idiots. Dismantling what gives them strength and advantage for nothing but ideology. Never works out well history says.

Day 7: Home, Jasper to Edmonton. First time in Jasper since the fire. Lots of rebuilding, sad to what was lost. The hostel we usually stay at burned down. Whistlers Inn accommodated us and give us space in the pub 🤣 for the exam. Work with what you have! A short stop at some dunes for funsies.

I can’t agree more, these headlines drive me batty. Most Albertans want nothing to do with this! Can we please stop giving a vocal minority such coverage? It is misleading and frustrating for the majority. Please talk about the 75% who DON’T want this. @theglobeandmail.com @carrietait.bsky.social

Day 6: 1st year field school, Radium to Jasper. Last full field day, starting at the Columbia River by Radium, type example of an anastomosing river. Critical wetland habitat. Mapping massive thrust faults in Sinclair Canyon, showing the growing of the Canadian Rockies, another favourite 🧵

Day 5: 1st yr geology field school, Fernie-Radium. My favourite day, I get to go home to the East Kootenays. The structurally curious Rocky Mountain Trench, big bad-ass Cordilleran ice sheet geomorphology, complexly deformed Devonian limestone, and travertine and tufa at Fairmont Hot Springs. ⚒️🧪

Day 4: 1st geology field school. What a stunner of a day, Robin egg blue skies, perfect temperatures. The students are spoiled as they learn about the formation of the Rocky Mountains, visit the famous Frank Slide, and marvel at the bizarre melinite (Ti-rich garnets) bearing Crowsnest Volcanics.

Day 3 Field School. Jensen Reservoir and Cretaceous Beach deposits, Del Bonita uplands outside the reach of the Laurentide Ice Sheet - a remnant periglacial landscape, and the Rocky Mountains. Hello Waterton and the Purcell Super Group, 1.3 Billion yrs old. Geologists- the ultimate time travellers.

Teaching EAS 110 First Year Field school. The badlands around Drumheller are as spectacular as ever. We also now have a mascot. #geology #fieldwork ⚒️

I love it, but hate it. 😫

Keep hope alive!

There are major threats to Canada's sovereignty right now. Losing our public broadcaster is one of them. The CBC -as we know it -will cease to exist if Mr. Poilievre wins on Monday. I think that matters. My substack is free to read; free to subscribe. open.substack.com/pub/caroloff...

A reminder that nominations are open for our executive and location for the next meeting. Please email [email protected] if you are interested before May 1st. This is a great opportunity especially for early career researchers- great community and network building! 🧪🌋⚒️

I think 5 might be my favourite. I ❤️ 🦫 ton

Certain partisans have been citing Canada's performance on per capita GDP as evidence of a supposed 'lost decade' and economic mismanagement. In @irpp.org's Policy Options, I deconstruct this arbitrary and misleading statistic, in two parts. #cdnecon #cdnpoli. /2

Classic 2000s-2010s Canadian indie Malajube, Montréal -40C I might make this a thread open.spotify.com/track/25R7WC...

The Sierra Nevada Earth Atlas showcases California’s longest and tallest mountain range and its iconic geologic features. It represents the most current, complete, and largest-scale, range-wide syntheses of geoscience data. Learn more - www.conservation.ca.gov/cgs/document...

Bears may be curious neighbors, but in Alaska, their interest in seismic stations poses a real challenge. They can dig up cables, chew into seismic vaults, and damage enclosures. Researchers now implement bear-resistant designs to better protect remote stations and ensure continuous monitoring.

Fun! I had an undergraduate researcher who worked on a project that included this eruption. ⚒️🧪
