New study: As lice pressure increased, the specific growth rate of returning fish declined. "Wild-origin fish had a greater return rate than hatchery-origin fish at all levels of lice infestation pressure, with the difference increasing with increasing pressure" academic.oup.com/icesjms/arti...

I'm currently looking for an MSc student to characterize water ages and storage in cold catchments. Several potential projects available, and I will support students who want to develop their own! If interested, please reach out soon at [email protected], as Sept 2026 app deadlines are approaching!

Gonna highlight another example of how you can think things are bad or getting worse when the opposite is probably true. Here's a story framed a certain way last year while I was still on vacation. Takeaway: "the province is a dangerous place for pedestrians and cyclists." But is it true?

Hot off the press! New paper characterizing storage and release processes in two permafrost catchments with @theoryofciaran.bsky.social @seankcarey.bsky.social. We characterized these processes by closing the water balance, EMMA, and StorAge Selection Functions (1/n) doi.org/10.1029/2024...

You know you're a grizzled late-stage PhD student when the first year students, on campus for the first time, hold the door open for you and call you 'sir'. T+2 days

⌛ Clock's ticking down but there is still time to submit your abstract to the best AGU session this year, H126 River Water Temperature! There are options to present virtually as well as in-person in New Orleans. Abstract submission deadline is Wed, 30 July, 23:59 EDT!!

A fantastic job opportunity for someone to work at the interface between Atlantic salmon habitat modelling and management. Cutting edge research as part of an excellent project team.

1. Accurate (unbiased and precise) quality controlled data are essential for understanding and monitoring trends in river temperature. However, researchers often collate and analyse data without consideration of these issues. A new 📜 & summary🧵 onlinelibrary.wiley.com/doi/10.1002/...

#AGU25 abstracts are due July 30! If you're doing any work on river temperature, we'd love to see you in New Orleans this December!! With: @andrasszeitz.bsky.social, @freshwaterflows.bsky.social, and #LorrayneMiralha

1/3 🧵 📢 ‼️ Are you interested in stream temperature and stream temperature modelling? Well you're in luck! We are organizing a workshop on stream temperature modelling at with presentations and guided discussions, at UQO in Gatineau, QC, October 15 - 16. More details in thread below! ‼️📢

New paper alert in HESS with Erin Nicholls and @seankcarey.bsky.social ! We used generalized additive models to assess the drivers of seasonality in stream chemistry across ten permafrost catchments in the Yukon Territory! (1/n) hess.copernicus.org/articles/29/...

Wow, here's the Yukon River ice break-up in the territory of the Trʼondëk Hwëchʼin. Our research group at YukonU had boots on the ground and eyes in the sky (plane/UAV) to make observations. These observations help researchers create models to better predict and respond to flooding due to ice jams.

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

We're thrilled to share that CJES, a @cdnsciencepub.com journal, will be joining the BlueSky community soon! Stay tuned for updates as we prepare to connect, share, and engage with researchers and science enthusiasts in this exciting space. See you soon! 🌟 #ScienceCommunication #BlueSky

Calling all US and Canadian students thinking about graduate studies! Come study science at #SFU in beautiful British Columbia, Canada. Graduate admissions have been reopened. Apply by April 25th. ⚛️ 🧪👩‍🔬🎢 🇨🇦

NEW PAPER, JUST OUT! 👀 Insects from the '70s and '80s were already collecting microplastic, decades before the term microplastic even existed. 🤯 A thread on the surprising history of this pollutant and the incredible insect larvae that helped us uncover it. 🐛 Let's dive in! 🧵👇 1/x

Field season 2025 underway. Have a feeling it will be an early spring in Yukon. @rtutto.bsky.social @dbarrett867.bsky.social and Calvin doing all the work.

Happy field work Friday! Had 2nd year undergraduate students out measuring stream flow on @mcmasteruniversity.bsky.social west campus this week for a hydrology lab session. Despite a couple leaky waders, the students loved the practical hands-on experience. We saw a mink too! 🦦 #Neature

First paper of my PhD published, woo! It asks how stream thermal sensitivity is influenced by northern environmental factors *cough* permafrost *cough* Key pf. take-away: permafrost may both increase and moderate thermal sensitivity. Get the details here!: hess.copernicus.org/articles/29/...

I've started working on this starter pack (Hydrology+Hydrogeology+Water in general) to help friends/colleagues who are migrating from the other place. Please note that this is work in progress and that more people will be added. Feel free to suggest BlueSky handles in comments. go.bsky.app/2h9ouZY

I made a Water Science 💧 Feed! I already added some folks to it and am slowly figuring out how to add more folks, but if you use "hydrology", "watersci", "waterscience" or the 💧 it should pop up in the feed! If you can't find it, let me know and I'll try to add you!

Another field work photo from Yukon, Canada. This one shows pH dependent mineral precipitation at the confluence of two streams. The white colour is from aluminum precipitates and orange colour is from iron precipitates. This phenomenon results from natural weathering of shales.

For any ecohydrologists on bluesky, does this look like beaver chew?

First salt tracer study successfully completed in my Yukon study streams!! Lots of surface and subsurface transient storage in these permafrost-rich headwater streams. Having some good tunes makes the stirring much easier. Many thanks to Matt Lindsay at USask for lending the geopump!
