This year's field kit 👇🏼was particularly minimalist😬, allowing us to sample as many #Greenland lakes as possible, to find the traces of tsunamis, triggered by rockfalls, in the wake of rapidly retreating #glaciers.

🧪 New research reveals that plants and algae survived in a Arctic lake on Svalbard, during the coldest phase of the last ice age, when the region was thought to be buried under ice. How is that possible? Read this paper led by @willemvdbilt.bsky.social bjerknes.uib.no/en/news/arct...

🏔️Heinrich Event 2 was preceded by atmospheric warming, supporting the view that Heinrich Stadials were marked by extreme seasonality and not year-round cold. 👉Read more here: www.nature.com/articles/s43... @willemvdbilt.bsky.social @bjerknes.uib.no

📢 Interested in µm-scale scanning of lake sediments? Then consider submitting an abstract to our session 👇🏼 at the @ialipa2025.bsky.social conference, hosted 6-10 October in Aix-les-Bains. You can do so until May 30 📅, using this link: lnkd.in/dDeyrHGx. @gfz.bsky.social @bjerknes.uib.no @unibe.ch

📢 Preparations for the 3rd Paleolimnology & Limnogeology International Symposium are in full swing! We invite submissions to our Glacier variability session VI-1 🧊 🌐 ialipa-2025.sciencesconf.org/resource/pag... @virtual-ialipa2025.bsky.social @willemvdbilt.bsky.social #lake #sediment #GLOF

An impression of the field campaign that led to a recent paper in @commsearth.bsky.social about the potential role of increased snowfall in a warmer Arctic on regional glaciers: youtu.be/l8CvcqjGM1Q @bjerknes.bsky.social

Proud to see this one out, led by #PhD A. Auer at #UiB and the @bjerknes.bsky.social. Our findings show that #Svalbard glaciers survived warmer-than-present past conditions because snowfall increased. Could this slow current retreat? Check: www.nature.com/articles/s43247-025-02064-z

A call for abstracts to our @eurogeosciences.bsky.social #EGU2025 "Winds of change" session 👇. Do you work on polar coastal sediment archives to extract information about past changes in storminess? Then consider submission via lnkd.in/dq-xh8mu. Happy holidays 🙏

@bjerknes.bsky.social wrote a really nice piece about our @natureportfolio.bsky.social research into the links between storminess and climate in the Arctic, and why we ought to care about the impacts this might have on the carbon cycle. bjerknes.uib.no/en/article/w...

Very proud and pleased to see our 10 000 year perspective on the links between Arctic storminess and climate change published in @natureportfolio.bsky.social today 👇🤩: www.nature.com/articles/s41...

Short impression of this summer's 1700 km long sailing trip to study the ancient raised beaches on Svalbard (Svenskøya island) and learn more about the links between ice sheet evolution and sea-level change in the past.

This isn't Mars, but Svenskøya, a small island in the eastern Barents Sea. Dating bone and wood from old beaches will hopefully deepen our understanding of links between ice sheet and sea level changes @bjerknes.bsky.social

During our 1st attempt to core this Svalbard lake, we found it ice-covered. We had more luck later. The sediments contained dense layers. Microscopy shows these contain minerals that form when oxygen is scarce. In the Arctic, such conditions are often caused by what hindered coring  - ice coverage.

Torn sediments, slumped at a 90-degree angle, and a turbidite on top: diagnostic features of an an earthquake deposit. This one happened 9500 yrs ago on Arctic Svalbard as rapid glacier melt re-activated faults: will this happen again in the future? @bjerknes.bsky.social

These Svalbard sediments cover the past 100 yrs. Molecular imaging allows 100s of temperature biomarker measurements on this slice of mud, and compare these against weather data. This new approach places recent Arctic summer warming in a 14000 yr context @bjerknes.bsky.social

Looking for a 3-year PostDoc to join our team at University of Bergen in the #ISLAS_project and #ISOSCAN to work at the interface between meteorology and hydrology. Use stable isotope models and data to study how Scandinavian mountains extract water from weather systems: tinyurl.com/imetb
