Protest gegen Budgetkürzungen: Universitäten setzen gemeinsames Zeichen in Graz

When Einstein developed general relativity the closest thing to a practical application that could even be imagined at the time was a slightly more precise description of where to look for the planet Mercury in the sky, and yet now we’d all be literally lost without it. Anyway: fund basic research.

For how much longer will it be possible to carry out national 'glacier inventories'? 🔥🧊 The latest Austrian glacier inventory (AGI 5, mostly representing 2023) shows that glaciers cover 285 km² and that 129 km² were lost since AGI 3 (~2010)! 📈😲 A third lost in less than two decades! 😱

Guten Morgen mit einem aktuellen Satellitenbild 🌍 Zum astronomischen Frühlingsbeginn verläuft die Tag-Nacht-Grenze senkrecht, weltweit dauert der Tag rund 12 Stunden.

I'm honored to share that I didn't post some nonsense to LinkedIn humble-bragging about something that isn't particularly noteworthy.

We are situated in Graz #Austria and this is the view from the Schöckl mountain on Jan 19 2026 23:00 CEST. #spaceweather #aurora #polarlights

INCREDIBLY massive avalanche struck the Elbrus resort (Kabardino-Balkaria, Caucasus, RU) today on the SE face of Ebrus, down to ~2300 m asl! ❄️🌊 Via @WeatherMonitors

GUESS WHAT WEEK IT IS

Short #orf feature on geography @uni-graz.at research at Pasterze glacier salzburg.orf.at/stories/3321... happening each year in September

Juni-Rekordhitze in Kärnten: 38,1° in Feistritz ob Bleiburg - eine so hohe Temperatur wurde in Kärnten im Juni noch nie gemessen. Auch in Klagenfurt 37,9°. 🔥

Preparations underway at Sermilik Station!🔧❄️ A UNI Graz team is heading north soon to finalize Austria’s first polar research station before scientists arrive in August. Big thanks to all involved!🏔️ 📸 © Steinegger & Ruhsam #SermilikStation #PolarResearch #APRI #Fieldwork #Arctic

#FieldworkFriday from Freya Glacier, Greenland❄️🌎 A Team from Geosphere Austria conducted glaciological fieldwork at Freya Glacier in Northeast Greenland. They also fixed the Webcams at the Glacier that you can find on our Website 👉 www.polarresearch.at/multimedia 📷 B. Hynek, A. Neureiter

Stunning overview of the former bed of the now gone Birch Glacier shot yesterday from the right lateral moraine 😲😱 INCREDIBLE to think that there WAS a glacier here just a few days ago! The area above the glacier still holds ~300,000m3 of debris Source D. Farinotti - @vaw-glaciology.bsky.social

Inspired by previous posts of @subfossilguy.bsky.social sky.social‬ and nice visualizations of @stim3on.bsky.social, I created a before and after 3D visualization of the tragic events at Blatten & Birchgletscher. Made possible b#swisstopopo Rapid Mapping imagery and their open data policy

Yesterday's devastating #glacier collapse erasing the Swiss village of Blatten still leaves me speechless... The high mountain areas are adapting to ever increasing temperatures. It's time to wake up! When, if not now? This is not far away but right here... pic: Pomona/A. Amherd

Es regnet, der Boden sieht wieder feucht aus... Dürre vorbei? Zur Einordnung, hier ein paar Bodenfeuchte- sowie eine Niederschlagsmessung vom @bayceer.bsky.social an der @unibayreuth.bsky.social. Kleiner 🧵

The river level has already started to rise behind the dam in Blatten! 🌊 A lake is underway... 😨 To 'mitigate' flooding hazard in the valley, the Ferden dam lake, located 6 km downstream has been emptied. 📷 SRF

Are you working on glacier monitoring using UAVs? Do you face challenges in computing glacier surface velocities due to strong glacial surface changes & decorrelation? Our new paper shows that deep learning methods may be a solution where other methods fail: www.frontiersin.org/journals/rem...

Spring is here at 2470 m.a.s.l.😳 Location: Border Rätikon-Silvretta, Vorarlberg

Today is the first World Day for Glaciers. However, in Austria, glaciers are rapidly vanishing. Here is a 3D comparison of Pasterze 1969-2018. In 2018, the glacier tongue was still well connected to the accumulation area of higher areas. This will soon change: www.derstandard.de/story/300000...

Geographers’ achievement unlocked 😉: had the chance to make a (tiny tiny) contribution to the new school’s atlas for Styria by compiling and coloring the Sentinel-2 mosaic for this nice remote sensing map www.schulatlas.at

End of summer is field work season. This is our drone mapping #rockglaciers, which are important climate indicators, in Hohe Tauern National Park. The resulting orthophotos allow us to derive flow velocities and compare them with climate trends. #GeoGraz #Permafrost Monitoring

Do trees still cool cities despite extreme heat and drought? Yes, but tree species cooling potential strongly varies. This and more in our new #thermal remote sensing publication - covering the current #heatrecord in Franconia in 2022 www.mdpi.com/2072-4292/16...

Etwas Eigenwerbung: diesen Donnerstag werde ich - im Rahmen des Kolloquiums des Instituts für Geographie und Raumforschung @UniGraz - über Geographische (Fern-)Erkundung im Hindukusch und Pamir sprechen (30.11., 18:00 Uhr, Heinrichstr. 36, Graz, HS 11.03, Foto: Sayeed©WCS 2016)

Huge team effort including data of more than three expeditions - a short thread on our new paper with @TheWCS: we present a detailed approach to assess grazing intensity & sustainability in high mountain rangelands with remote sensing & field data (1/10): www.sciencedirect.com/science/arti...

An intense, fun and successful summer field season is slowly ending - surveying glaciers & rockglaciers with cm accurate RTK UAVs. This week we contributed to the over 100 year long glacier survey of @oeav (gletschermessdienst) by photogrammetrically deriving the edge of Pasterze
