Thick exposures of Quaternary sediments in the Churchill River area record at least three glacial-interglacial cycles and provide valuable insights into past glacial dynamics and interglacial climates. A fun area to work in. doi.org/10.1139/cjes...

Photo from the Laurentian Highlands of Quebec, after which the Laurentide Ice Sheet is named. We got here by driving upwards ~ 1000 m from sea level at Baie Saint Paul.

If you're wondering what's happening with the US Forest Service and why it matters, read this:

Did you know? Pixar’s film, Hoppers, worked with real scientists to reflect real-world ecology. 🦫 Dr. Emily Fairfax, one of the experts, also authored GSA Special Paper 562, showing how beavers support biodiversity and help landscapes recover from wildfire. 🔗 Learn more: geosociety.co/beavers

Udder disaster my friends!

Capturing the moment flowing water turns into ice (a mineral).

"I'm not saying you should resist in spite of the risk [but] BECAUSE of the risk. The risk is what helps you remember... there's something that learning is for... thinking is for... work is for... YOU are for, the discovery of which belongs to you." medium.com/center-on-pr...

It's important to thank the volunteers around you. We all do it for different reasons, and are there for the ups and downs. Here's to more ups and thanks to all who I have volunteered with over the last 20 years.

Schools cancelled so it's time to go for a walk.

Guess what. Glaciers aren't as good at eroding the landscape as we might have thought. New paper with collaborators from Quebec, France, and across the US. Internationalism lives on at least in science! gchron.copernicus.org/articles/8/1... ❄️🧪💙📚 #scicomm #climate #UVMresearch #science  🌎 🔬 ⚒️

After about 5 years (!) of keeping secrets, I am so excited that Disney Pixar's Hoppers is finally coming out on March 6th! Back in 2021, Pixar emailed me asking if I could give a talk about my research to their employees. Then another talk. And another. 📸 Disney/Jesse Grant/Getty Images

Our new paper is out, in proper format, in CJES today. It's a continuation of our stratigraphic framework development in the southwest HBL, together with Paleo environment data (UofT) and optical dating (UFV).

Absolutely true - I am more and more aware every day of the need to question established 'common knowledge'.

I also told students to me more like the cuttlefish - again, don't take the marshmallow because it is quick and easy and right in front of them

Happy Halloween!

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

Stopped the bike ride for a little geology. Fascinating mud cracks that peel off in layers, and sticky clay underneath. Little minds shocked and amazed when they learned that mud cracks are found as 'fossils' too. #geology

Congratulations to Mr. Mesich who successfully defended his MSc today at UWaterloo. It's been a pleasure serving as your co-supervisor with Dr. Ross. *Quaternary stratigraphy of the Gods and Yakaw river areas, northeastern Manitoba*

Fire-induced rock spalling! This area burnt about 1-2 months ago. All of the little rock shards on the ground are spalled pieces of the granite boulder, overlying burnt soil and moss. Before seeing this in person, I didn't really consider the mechanical weathering effects of fire!

Sometimes dogs are just ridiculous.

Campground foraging near the Manitoba Escarpment. A lot of work for a little bit butter. Makes me grateful for farms and grocery stores.

It's not often that a senior professorship in paleolimnology comes long, but here is one great opportunity. Deadline September 10. If you consider applying and wonder what the process is like, feel free to reach out to me! www.queensu.ca/vpr/crc/oppo...

Prairie skies just after the storm. Also have the requisite train and crops.

I just started writing a thread about all the misinformation I am seeing around the tragedy in Texas but this article covers everything I wanted to say and more. Please read it:

If you're looking for graduate opportunities related to the Pleistocene extinctions, megafaunal impacts on ecological resilience, or the timescales of ecological recovery from perturbations, I'd love to support a Simons Fellowship applicant.

I presented to 5 classrooms today on the topic of Geoscience Careers and Sustainability. It was the first time I really had to think about presenting geology from a sustainability perspective to kids so young - but it turns out there is lots of information like this poster!

Beautiful rat-tail striae formed at the resistant head of fossils in limestone, near Ottawa Ontario. #gac-mac field trip thanks to Riley Mulligan!

Womens are Persons. The Famous Five brought a case before the highest court to appeal a 1928 decision by the Supreme Court of Canada. That court had ruled that women could not be appointed to the Senate, because they were not "qualified persons." On October 18, 1929, they reversed this decision.

Important news for users of ArcticDEM - due to funding cuts, no more DEMs will be produced for the foreseeable future. 🧪⚒️❄️

This request is for a geologist who knows ASL.

This is a fantastic resource, highlighting differences in terminology between disciplines to help us all work together better.

This! Science progresses through fieldwork, discovering what is actually there and then adjusting your hypothesis accordingly. If you must do a desktop-only or geophysics-only study, please clearly state that it is of limited value and should be verified by fieldwork.

Want to come and do a PhD in Palaeo Glaciology and numerical ice sheet modelling at Sheffield Hallam? @niallgandy.bsky.social, myself and Bob Jeffery are advertising a fully funded PhD Studentship. The closing date for applications: 17:00 (BST) on Thursday 17th April 2025. tinyurl.com/2ab5mdhf
