Minimalist lake coring in Scoresby Sund, East Greenland

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.

Lake persisted where ice was expected in Arctic oasis Researchers discovered that plants and algae survived in a small Arctic lake during the coldest period of the last ice age, when the area was assumed to…

🧪 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?

YouTube video by Bjerknes Centre for Climate Research Did Åsgardfonna on Svalbard survive during a warmer past?

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:

Hydroclimate intensification likely aided glacier survival on Svalbard in the Early Holocene - Communications Earth & Environment The Åsgardfonna ice cap in Svalbard did not melt entirely during the Holocene Thermal Maximum and possibly advanced despite the warmer-than-today climate, due to seasonal sea-ice loss enhanced snowfal...

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 🙏

Wild is the wind - Arctic lake records 10 000 years of storminess and reveals a big surprise Researcher Willem van der Bilt was surprised that the results of a project on storminess in a less icy Arctic showed the opposite of what was expected.

@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.

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 👇🤩:

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
