Toolik Field Station

Awesome event from @polarsecco.bsky.social!

Hi there :) We're just a scientific research station in Arctic Alaska, run by University of AK. We study things like how the tundra responds to environmental changes or properties of the aurora borealis. Nothing suspicious about us but verify for yourself by visiting our website. www.uaf.edu/toolik/

The university is committed to a policy of nondiscrimination (http://www.alaska.edu/nondiscrimination) against individuals on the basis of any legally protected status."

Toolik Field Station is seeking a GIS & Remote Sensing Manager! Join us on Alaska's North Slope to support Arctic science. Candidates need experience w/ GIS systems, surveying & analysis, team & project management. Work is split between Toolik & Fairbanks

Line graph of daily temperature averages (1990-2020) vs. 2025. Y-axis displays temperature in celsius; x- axis the Julian day of the year. Temperatures in July rose above 25C. Lowest temperature was in late December of around 40C.

Wonder what last year's temperatures were like in comparison to the prior 35 years? Check out this graph from our Environmental Data Center manager @ubetula.bsky.social .

Midsummer was hot, hot, hot! But it still snowed every month of the year.

Great new resource from @arctictogether.bsky.social!

Great day @toolikfieldstation.bsky.social. Not only is the lake officially ice free but I got to get out via helicopter to a thermokarst lake to the south of Toolik to work on an eddy covariance tower.
Pretty good day all in all.

Ever wish you could visit Toolik? Now's your chance! Come for our Visitor's Day, June 6, 9:30a-4p!

Immerse yourself in the sights & sounds of the tundra w/ our Naturalist & tour Toolik facilities & long-term research sites. Learn more at uaf.edu/toolik/news/50th-year/visitors-day.php

Costume day in the field @toolikfieldstation.bsky.social today. Thanks to everyone for bringing colour to the tundra!

We're celebrating 50 years of Toolik with a special collection in Arctic Science @arcticsciencej.bsky.social . Thinking about publishing your Toolik research? Consider submitting to this collection!

Line graph of Toolik Lake Ice Thickness 2012-2025 and Ice Off dates (2021-2024). 2025 ice thickness was higher than the 2012-2024 average.

Hot off the R-press! This winter's ice thickness on Toolik Lake. Any bets as to when it'll be ice-free?

Thanks to Amanda Young @ubetula.bsky.social and Toolik's hardy year-round Spatial and Environmental Data Center team.

As anyone who's spent time at Toolik over the past 50 years knows, it's much more than a research site. Embedded within sample collections & lab analyses are moments to gain confidence, to develop a connection with the land, to start a lifelong passion. givingday.alaska.edu/amb/toolik

Muskox battles, endless ptarmigan, migrating birds and more! Our seasonal naturalist Seth Beaudreault had quite the first day back at the station with wildlife galore. Read more about it in our Naturalist Journal, updated daily.

A Major Climate Force Has Been Ignored for Decades Small mammals play an outsize role in shaping the world around them.

I’ve spent a lot of time thinking about big animals—🐋🐋🐋—but over the last year, I’ve had a chance to learn more about the big role of small critters. Like voles in the tundra carbon cycle 🐭(also my first attempt to write about biogeochemistry, gah).

Oh the beauty of a clearing Arctic winter sky!

Well we are not quite as chilly as Fairbanks or Cold foot here at @toolikfieldstation.bsky.social but it is still -40 out so it is pretty darn cold.

Today I spotted a small flock of ptarmigan browsing in the willows around the station and basking in the sunlight.
