After two busy days at @agu.org #OSM26 with multiple presentations from our team, today is a bit “quieter” - but the one presentation shows some neat results:
Sandven et al. - The Role of Colored Dissolved Organic Matter in the Ice-covered #Arctic Ocean Lightscape: 14:10-14:20 Hall 1 (SEC)
Several interesting presentations with contributions from our team today, on day two of the @agu.org #OSM26 conference. Tune in for some exciting #Arctic and #Antarctic marine #science.

The 11th China-Nordic #Arctic Cooperation Symposium at the Fram Centre started with some insights for plans for the upcoming International Polar Year. Arctic shipping is also high on the agenda during the Symposium. All wiith the backdrop of current affairs in the Arctic. #CNARC #npolar
How do we measure the concentrations of Iodine-129, a radionuclide that we use as a water mass tracer, in the seawater samples collected during our expeditions?

New paper alert! 🚨📄 Sumata et al. explore the effect of thinner #Arctic sea ice on ice-ocean interaction using a coupled ice-ocean model that takes into account the changes in the roughness of the ice - in @egu.eu GMD - contribution of #H2020 @crices-h2020.bsky.social

NPI scientists currently conduct ecosystem research on the @biodiversa.eu WOBEC cruise with @awi.de R/V Polarstern in the Southern Ocean, including work on sea ice. Read more here: instagram.com/p/DTkpb4IiLvn

Preprint alert! 🚨📄 Itkin et al. explore the use of multi-frequency electromagnetic induction measurements to examine the consolidation of #Arctic sea-ice ridges using rare year-round data from the MOSAiC expedition.

🎉Happy New Year!🎉
We wish everyone a good start into 2026 with some impressions from the Antarctic ice shelf 🐧

Preprint alert! 🚨📄 Sandven et al. explore the often overlooked regionality of seawater optical properties across the central #Arctic Ocean, largely driven by presence or absence of terrestrial runoff, and how this affects 🌅☀️ light-related physical and biological 🦠🐟 processes in the upper ocean.
✨Season’s Greetings to our followers from the Ocean and Sea Ice sections at the Norwegian Polar Institute!✨

Busy days at the Fram Centre, with the annual meeting of the Atlantic-Arctic Distributed Biological Observatory (A-DBO) arranged by H2020 Arctic Passion. Many in-person and online presentations of activities in 2025 contributing to A-DBO. Lots of exciting activity in the past year!
New paper alert! Platelet ice is a unique type of sea ice that forms in supercooled waters beneath the Antarctic ice shelves. A new study in @meps-ir.bsky.social sheds light on the role of platelet ice for sea ice algae in the Southern Ocean: doi.org/10.3354/meps14979
Last week, our team aboard R/V Kronprins Haakon managed to reach the Hartogbukta glacier front and measured ocean temperatures above 3°C, evidence of the ocean’s role in the record melting the Austfonna ice cap on Svalbard has experienced in recent years. Read more: instagram.com/p/DRCay2wiBnl

New paper alert! 🚨📄 Recent study in Frontiers in Marine Science argues that #Arctic sea-ice ridges provide more potential habitable space for ice-associated algae🦠 in spring than level ice. But often ridges are omitted in field studies, since they are difficult to sample. doi.org/10.3389/fmar...
New paper alert! 🗞️🚨 In @natgeosci.nature.com - on terrigenous dissolved organic carbon in the #Arctic Ocean, led by @awi.de, based on data from the MOSAiC drift expedition.
North of Svalbard, the Sun no longer rises above the horizon and polar night has begun. During our expedition aboard RV Kronprins Haakon, we collect data during the freeze-up period, as the ocean transitions from its summer to winter state. Read more: instagram.com/p/DQeY0HGiLpN

Workshop on #Arctic observations in Yokohama 🇯🇵 pending the launch of 🇯🇵 research icebreaker Mirai II next year.
The last working area of the @awi.de expedition PS150 on board #Polarstern is located close to the coast of northeast Greenland, at the floating terminus of the 79 North Glacier, offering amazing views of the fjords, mountains and glaciers.

The Maud is perhaps a lesser known polar ship than its counterparts the Fram and the Gjøa, that can be visited at the Fram Museum (Oslo). But Maud still made a great contribution to #Arctic #exploration and #science, and is now back on Norwegian soil.
