On the return from a research trip to Disko Bay, Greenland with colleagues from quaternary science Dr Kathryn Adamson & @iestynbarr.bsky.social working with @kirstenseesternc.bsky.social at @arcticstationucph.bsky.social - so much to process from another humbling encounter with ice and place.

Today we spotted two #Bowhead whales ((Balaena mysticetus) right outside the station at the sea ice front. The majestic Greenland right whale are special for #Disko_Bay and their singing is captured in real time by #hydrophones and broadcasted as part of the diskolive.com/the-animals#... project.

Just arrived in #Qeqertarsuag to work at @arcticstationucph.bsky.social for a short while. Fascination to watch the vanishing sea ice and the fragmented snow cover on land. #Spring is setting in it seems. Look forward to team up with the lovely station staff and scientists visiting the station.

Truly happy to be partner in one of the nine Arctic projects recently funded by #NordForsk. Our project: Arctic freshwater food systems - influence of warming winters and increased snow cover (FROST), will contribute to a sustainable development of the Arctic.

A fishy day at #UNIS for the limnology class. Guest teacher @grimsruddavidsen.bsky.social taught about ecology and behavior of #Arctic_charr. Fascinating how this 🐟 species coop with living in the #Arctic. Students got hands-on experience with modern fish tracking equipment. @limnology.bsky.social

Asked the UNIS #limnology_students to formulate #hypotheses about the effect of climate changes in Arctic lake food webs and to create doable in-situ experiments, that could provide answers. Creativity was high ranging from whole year mesocosms studies to fertilizing #lakes with goose droppings.

Wash and fine-sieve mud from the bottom of an arctic lake and you´ll find head capsules of #Chironomid mosquito🦟 larvae. We did so at the #UNIS freshwater course with Simon Belle from #SLU. Some specimen were truly old (~200 y) but 100% intact and are part of a climate story. #Paleo_limnology

There are challenges to do #freshwater sampling in -20oC through 95 cm ice, but this international class at #UNIS_Svalbard runs the whole operation smoothly. They collects under ice light profiles, water samples and plankton. Nothing competes learning by doing. @freshwaterscience.bsky.social

Bravo, @sannemdt.bsky.social for a new study on microbial biofilm in Greenland streams across 3 regions. Highlights:
🟢 Cyanobacteria thrive even in the High Arctic
🌡️ P & water temperature are key drivers of biofilm growth
⛰️ Catchment slope & NO3 conc shape total biomass

Today the Limnology-class at #UNIS_Svalbardwe had a very successful fieldtrip to the backland for sampling two mountain lakes. Air temp -22oC and water temp at 7 m depth +2oC. Ice thickness 1 m. Plankton in the nets? Oh - yes. @fblucph.bsky.social @jakobgiesler.bsky.social @rubensh.bsky.social

Daily life at #UNIS-Svalbard. Fieldwork is a prominent aspect of all courses offered at this university. Last Friday the entire limnology💦 class went on their first #winter-sampling event. Ice thickness was 83 cm and with a lot of snow on top. Higher education when it´s best @fblucph.bsky.social

Daily life at #UNIS-Svalbard. The return of sunbeams in #Longyearbyen is always celebrated on March 8 - whether the ☀️ appears or not. It did and the iconic miner in the middle of the town also go a sun crown.

Salmon fish folks; here's a 2 y post doc position with a great team of reseacher working in beautiful lanscapes. Highly recommended.
We are looking for a post doc (2 year position) to work on fundamental and applied salmonid migration ecology. Work place is Eawag in Kastanienbaum, Switzerland, located on the shores of Lake Lucerne. See more here:

Daily life at #UNIS-Svalbard. Aurora borealis is mind blowing and happens often at 78oN.
I’m mostly at loss for words lately with the state of the world. But can offer a timeline cleanse of northern lights from my dog walk yesterday evening.

Daily life at #UNIS-Svalbard. The short legged Svalbard reindeer (Rangifer tarandus platyrhynchus) walk the village with no fear of humans (until the hunting seasons starts).
This subspecies is only found on the Svalbard archipelago and is smaller than the Norwegian common reindeer.
