It was a pleasure and an honor to be part of this excellent initiative by #SVT. Thanks to #CalleElfström #PatrickBratt for great collaboration!

Winter has come to Tarfala meteorologically www.svt.se/nyheter/sapm.... This often means irregular transmission from our #TimeLapseCamera at #LakeTarfala. Ice-on happened between 7 and 22 october, the "normal range" bolin.su.se/data/tarfala... @bolincentre.bsky.social @stockholm-uni.bsky.social

New collaborative paper out, with results on lake-terminating Kaskasapakte Glacier in the surroundings of #TarfalaResearchStation @bolincentre.bsky.social @stockholm-uni.bsky.social, looking at its retreat dynamics through the lense of increasing lake temperatures. tc.copernicus.org/articles/19/...

Correction: the record minus year was 2024, not 2022. Should also be corrected now at SverigesRadio's site. And Time Lapse Camera imagery from 30 minutes ago shows snow in the Tarfala Valley :) @stockholm-uni.bsky.social @bolincentre.bsky.social

New book chapter - Entire book to be published 2026 @stockholm-uni.bsky.social . Andreassen, L.M., Hagen, J.O., Kirchner, N., et al., Glaciers in Scandinavia, Svalbard and Jan Mayen, Reference Module in Earth Systems and Environmental Sciences, Elsevier, 2025, www.sciencedirect.com/science/arti...

And here comes the snow ❄️ Summer is indeed short: Left: today. Middle: 14 june. But there WAS summer in between (Right) 😀Last post from the station tomorrow @stockholm-uni.bsky.social @bolincentre.bsky.social

And here comes the snow ❄️ Summer is indeed short, on June 14th the twin cabins were STILL in snow (picture to the right) 😀But there WAS summer in between! Last post from the station @stockholm-uni.bsky.social @bolincentre.bsky.social tomorrow :)

First nightfrost, followed by a beautiful sunny morning, captured by our Time Lapse Camera at #LakeTarfala. These are the last days before closing the station @stockholm-uni.bsky.social @bolincentre.bsky.social after more than 3 months of 24/7 operation👍 #glacier #massbalance results to come soon!

End of season is approaching at Tarfala Research Station @stockholm-uni.bsky.social @bolincentre.bsky.social. Autumn colours at the station, #glacier #massbalance measurements in full swing @matthias-huss.bsky.social @vaw-glaciology.bsky.social @swisspolar.bsky.social, now also with a #SmartStake 👍

This year's measurement of Kebnekaise's southern peak by @tarfalaresstation.bsky.social shows that the peak has decreased by 1.5 metres compared to last year. This is the seventh year in a row that Kebnekaise´s southern peak is lower than the northern peak. #Climate #Arctic www.su.se/english/news...

Tarfala forskningsstation @stockholm-uni.bsky.social @bolincentre.bsky.social bidrar med en föreläsning om glaciärer och glaciäråret 2024/2025 som avslutas snart innan den första snön kommer (ja, ett glaciärår är inte samma som ett kalenderår 😀). Välkommen! forskarfredag.se/program/glac...

New paper out, on #Ryder #glacier #NorthernGreenland #icesheetmodelling. Great collaboration @bolincentre.bsky.social @stockholm-uni.bsky.social @uio.no @dartmouthears.bsky.social #jifresse tc.copernicus.org/articles/19/.... More about the swedish glaciers and their #massbalance 2024/2025 soon 😀

Tarfala Research Station's 80 yrs Anniversary conference concluded with an excursion to #Storglaciären and lots of discussions with international guests from US, Spain, Switzerland #WGMS as well as from #SwedishPolarResearch. Thank you all and @stockholm-uni.bsky.social @bolincentre.bsky.social

Day 2 of #TarfalaResearchStation s 80years Anniversary at @stockholm-uni.bsky.social in collaboration with the @bolincentre.bsky.social . Brilliant talks by excellent speakers, whose comments on the future of glaciers were caught be SVT#Sapmi www.svt.se/nyheter/sapm... www.svt.se/nyheter/vide...

Tarfala's 80 Year Anniversary Conference @stockholm-uni.bsky.social @bolincentre.bsky.social has just started! Thank your our international speakers from Switzerland, Norway, Germany and UK making the first sessions really exciting! Artwork in the conference logo by @dominoajones.bsky.social

Course GE5003 on #glaciers #alpine and #polar environments from @stockholmuni.bsky.social @bolincentre.bsky.social is leaving today, after experiencing #Storglaciären and the first snow of the season on the mountain tops in the #Tarfala Valley first hand. THANK YOU for having been great students!

After hot and dry came wet .. And Lillsjön, the little lake, became Storsjön, the large lake...Now we are back to "normal" (that is, Lillsjön is small again), but what is "normal"? In any case, today, we welcome course GE5003 @stockholm-uni.bsky.social @bolincentre.bsky.social, for a 10-days stay!

The @tarfalaresstation.bsky.social library is basically a rare books collection 😍😍 Every edition of Physics of Glaciers🕺from the size of each book, you can see how much this field of research has expanded in Paterson's lifetime

#Ice-off at #LakeTarfala @stockholm-uni.bsky.social @bolincentre.bsky.social was attained on July 31 this year, a month later than in 2024 bolin.su.se/data/tarfala.... As of yesterday, the first starry saxifrage are flowering around the station 😀

July was warm. Here are #warmingstripes @edhawkins.org showing average july temperature at #TarfalaResearchStation @stockholmuni.bsky.social @bolincentre.bsky.social. One definition of the Arctic is that July temps stay below 10 C - according to this, we are not in the Arctic...But we are...

Part 2/2. Also, check out goodbye-glaciers.info/glaciers/#Sc... where Swedish glaciers are first out among Scandinavian #glaciers. There, the "mostly gone" years for the Swedish reference glaciers are presented, and they are not in a far future @stockholm-uni.bsky.social @bolincentre.bsky.social

Part 1/2. I would like to thank 😍 all those wonderful people who sent supporting emails after watching TV4's new on July 30, www.tv4play.se/video/fc0ae7... c. 4.40 mins into the broadcast. Thanks also to @stockholm-uni.bsky.social @bolincentre.bsky.social for support!

Yes indeed 😀"Vernissage" yesterday, and art work will continue at others places at the station @bolincentre.bsky.social @stockholm-uni.bsky.social

Our new outdoor-info point @stockholm-uni.bsky.social @bolincentre.bsky.social is in the making! Now hikers on their way to #STF#tourist can read about the station and what kind of research is done. And #OpenHouse days with #STF#Kebnekaise continue throughout the summer as part of our #outreach👍

Data download and instrument maintenance at the #PACE #permafrost borehole at #Tarfalaridge @stockholm-uni.bsky.social @bolincentre.bsky.social @jeannettenoetzli.bsky.social successfully completed. @dominoajones.bsky.social joined to sketch the splendid views of #Storglaciäen #Isfallsglaciären.

This morning, we could observe a wolverine. Hard to spot against the rocks, but there are snowfields that still haven't melted away making it easier to spot 😀 @stockholm-uni.bsky.social @bolincentre.bsky.social More fieldwork today recovering data from the #PACE site at #TarfalaRidge. Pics to come

More snapshots from @tarfalaresstation.bsky.social ⭐️🕺

And sound artist #PabloDiserens is doing great stuff too for the IYP www.un-glaciers.org/en/art, we are very lucky to have the #FlowerOfGlacier film team at #TarfalaresearchStation @stockholm-uni.bsky.social @bolincentre.bsky.social - last day of their stay today, will be intense but sooo worth 👍

At TRS @stockholm-uni.bsky.social, directors #MyriamGras #CyaneFindji + team record for #FlowersOfGlaciers, a documentary about flowers in the #Storglaciären forefield, climate and plant community change, and 3 generations of female researchers starting with #AdelaideStork #Geneva #BotanicalGarden.

3rd course on #climate + #glaciers for #mountainleaders svenskafjalledare.se uimla.org completed, supported by @formasforsk.bsky.social. THANKS to all participants and extra teachers C. Williams #BristolUniv K. Larson @arcticcentreumu.bsky.social, P. Raker & M. Houssais @stockholm-uni.bsky.social

We are hosting guest researchers from the University of #Bristol through a #POLARIN grant #polar #microbiology. Yesterdays pre-field work reconnaissance hike to #Storglaciären showed an essentially still fully snowcovered #glacier. But melt is on the way - no more snow-shoveling around the station 😀

We just waved good-bye to colleagues Stina and Sara from the #botanicalgarden in Gothenburg #botany. Listen to #SverigesRadio #naturmorgon (in swedish) to learn about their project at Tarfala Research Station @stockholm-uni.bsky.social @bolincentre.bsky.social www.sverigesradio.se/avsnitt/serp...

Today:reconnaissance in the #Storglaciären #forefield with experts in #hydrology #botany: Freshwater streams, glacial streams & vegetation in the focus, and strengthening cooperation between @stockholm-uni.bsky.social @bolincentre.bsky.social @umeauniversitet.bsky.social on a lovely summer day!

TRS is now officially open for the season and our first guests are here for a writing retreat: PhD students from the Dept. of Geological Sciences @stockholm-uni.bsky.social @bolincentre.bsky.social And yes, we dont see much of the heat that is over other parts of Europe right now-still lots of snow!

Save the date for the Forum for the Arctic and Antarctic! @stockholm-uni.bsky.social @bolincentre.bsky.social www.su.se/bolin-centre...

New paper on area and frontal change of Swedish #glaciers during 2017-2023 in Journal of #Glaciology @igsoc.bsky.social @stockholm-uni.bsky.social @bolincentre.bsky.social @vaw-glaciology.bsky.social doi.org/10.1017/jog..... Make this must-read for all students/researchers arriving soon at TRS? 😂

Impacts have consequences: STF has wisely decided to guide only via the western route to Kebnekaise Southern Peak this year, not the eastern one. www.svenskaturistforeningen.se/om-stf/aktue...

Impacts of #climatechange 1st hand @stockholm-uni.bsky.social @bolincentre.bsky.social: At Tarfala, it currently is the coldest start into a year (1 jan-10 jun) since 1990. 2024 had the hottest one - Extremes back to back! Based on Positive degree days: 208 in 2024, 17 C in 2025. Data from our AWS.

The warm weekend brought forward the first barren ground and flowers around TarfalaResearchStation @stockholm-uni.bsky.social @bolincentre.bsky.social ! We are looking forward to welcome our colleagues from @arcticcentreumu.bsky.social soon who work with vegetation in #Storglaciären's forefield!

The twin cabins at Tarfala Research Station @stockholm-uni.bsky.social @bolincentre.bsky.social are melting out, so staff has moved in for the summer👍If you think it is a quite place-well, not always: This night, wind speeds of c 100 km/h caused a lot of noise and only light, interrupted sleep 😂

Today at the 7th Nordic STS Conference @stockholm-uni.bsky.social: screening of the forthcoming documentary "The Flowers of the Glacier" about a #herbarium, #womeninscience, and #Arctic climate change research, set at TarfalaResearchStation, Looking forward to more filming #MyriamGras #CyaneFindji!

#SAL Navigation and #KTH conduct sensor tests in Lake Tarfala! To lower the sensors into the lake, c 2 m ice need to be drilled through first :) Can we expect a later ice-off than in 2024? New data collection site @bolincentre.bsky.social @stockholm-uni.bsky.social : bolin.su.se/data/tarfala...

Pre-opening at Tarfala Research Station @stockholm-uni.bsky.social @bolincentre.bsky.social: great conditions for starting up the season and still lots of snow, and even some new during the night 😅Maintenance going on before our first guests arrive at the end of june. Sporadic posts until then.

Very proud to be able to share this: Our work on Petermann Ice Shelf, www.nature.com/articles/s41... @stockholm-uni.bsky.social @bolincentre.bsky.social #SwedishPolarResearch #SwedishResearchCouncil is out now

Register for Tarfala Research Stations 80 Year Anniversary Conference! @stockholm-uni.bsky.social @bolincentre.bsky.social @vaw-glaciology.bsky.social @swisspolar.bsky.social @matthias-huss.bsky.social #SwedishPolarResearch #SMHI. Artwork by @dominoajones.bsky.social bsky.app/profile/tarf...

Winter #Massbalance for #Sweden's reference #glaciers done @vaw-glaciology.bsky.social @matthias-huss.bsky.social @swisspolar.bsky.social. With 2.11 m w.e., #Storglaciären @stockholm-uni.bsky.social @bolincentre.bsky.social had the highest accumulation since 1992! More at www.su.se/tarfala-fors...

#Massbalance calculations @vaw-glaciology.bsky.social @matthias-huss.bsky.social done - #Storglaciären @stockholm-uni.bsky.social @bolincentre.bsky.social had the largest winter accumulation (2.11 m w.e.) since 1992 and the fifth highest on record. More results to come soon :) Happy Easter!

Long and windy, sunny-on-the-way-home day, fixing our automated weather station in Lihtti, a site important for #reindeer husbandry #Girjas #sameby. Some Data available here - not an easy lcoation for instruments :) bolin.su.se/data/tarfala... @bolincentre.bsky.social @stockholm-uni.bsky.social

Grounded in Abisko today, so we can share impressions from the last days at the station @stockholm-uni.bsky.social @bolincentre.bsky.social . On #Storglaciären huge crevasses were open which doesnt make #glacier #massbalance @vaw-glaciology.bsky.social (to be reported soon) easier or faster ...

#Glacier #Massbalance measurements for the reference glaciers @vaw-glaciology.bsky.social Rivgojiehhki, Moarhmmá and Rabots continue from Abisko @stockholm-uni.bsky.social @bolincentre.bsky.social We are curious to learn how much snow they got - Storglaciären was a total surpise - tbc indeed :)
