OSL dating by Lund Luminescence @LundGeology provide the ages for permafrozen sediments in the Laptev Sea to estimate organic carbon storage, thaw rates and greenhouse gas production in a just published study led by Birgit Wild Bolin Centre for Climate Research. rdcu.be/cUwU2

Getting dressed for success and safety! HF etching of luminescence samples with Edyta Kalińska Lund Luminescence @LundGeology.

I thought we were quite efficient but apparently we were working too slowly. Sediment sampling at Kivik, Scania for an OSL-dating project. @LundGeology Historiska museet vid Lunds universitet

How to teach geology students the tricky science (or art?) of visualising the sometimes invisible in 2D, 3D and 4D was one topic discussed in a fun workshop yesterday with Lena Håkansson and Anders Ahlberg SFU iEarth and colleagues @LundGeology. Got some new ideas to try out!

We need more research about storm surges in Sweden, and geological archives are an important part. Conclusions from a report that Caroline Hallin LTH vid Lunds universitet and I @LundGeology presented at Kustmöte 2022 Statens geotekniska institut today. lucris.lub.lu.se/ws/portalfiles….

It isn't a crater but something much cooler - a grounded iceberg pit! Happy to see my and Tim Johnsen's cosmogenic exposure ages finally published, contributing to a new paper about the Tor structure in Sweden onlinelibrary.wiley.com/doi/10.1111/ma… @LundGeology

Returning to @LundGeology from Copenhagen airport after having picked up 50 kg samples from the Svalbard #Cryocarb expedition - raised beaches waiting to be dated Lund Luminescence. Thanks Anders Schomacker for timely delivery!

Inspiration for teaching @LundGeology at the 2022 Lund University Conference on Teaching and Learning #LUTL2022 today. Some interesting perspectives on lifelong learning so far.

These glacilacustrine sediments from SE Norway have been dated to ca 56 ka and indicate that the Scandinavian ice sheet was almost completely gone by then.

All the clasts made sampling for luminescence dating tricky and hard on the knees. But what else to expect from a cairn?! Lund Luminescence @LundGeology in collaboration with Sydsvensk Arkeologi.

Happy to present OSL data from Store Mosse National Park at #LED2023 today. Got some useful feedback too - new ideas for more research! And certainly more to come during the rest of the conference hosted by DTU. Lund Luminescence @LundGeology

Tomorrow this should turn into a sediment flume @LundGeology! Excited! DevinSense TecQuipment

First water through the flume! Now installed and working @LundGeology Lund University thanks to Johan and Nils DevinSense with support from TecQuipment. Looking forward to playing with water and sand at work. Oops, I mean studying sedimentological processes of course.

First day of fieldwork in Finnmark and inauguration of the new spade today. It's white! For now. @LundGeology USN

View from the lunch moraine over an impressive glacifluvial landscape in Finnmark, Norway. A lot of water flowed here during the last deglaciation and we're trying to do a detailed reconstruction of the events. @LundGeology USN

Spending a rainy afternoon at base camp Turun yliopisto - University of Turku's Kevo research station, measuring portable luminescence samples and catching up with field notes. @LundGeology Lund Luminescence USN

Halfway through the fieldwork in Finnmark we have already taken more samples than expected and have to empty, wash and re-use sampling tubes. Good for science, bad for luggage weight. @LundGeology Lund Luminescence

Beautiful lateral meltwater channels during one of the last days of fieldwork in the Inari area, Finland with Alastair Goodship USN. Big thanks also to Pertti Sarala University of Oulu who joined for a few days. @LundGeology

Storm "Hans" gives an excellent opportunity to study wave action at rocky coasts. @LundGeology
