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.

📢 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

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 🙏

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
