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

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.

When one thinks of the summer in the #Arctic, one could often imagine endless peaceful icescapes shed by everlasting sunlight. But out on the ocean the reality is different: fog is what you would typically find here this time of year.

New paper 🚨 in #ASLO_LO @aslo.org describes a new proxy to assess the degree of photodegradation☀️of organic matter in the #Arctic Ocean. This is posed to increase with reduced #Arctic sea ice cover and this new method could be a way to monitor this in lack of other ways.

We left yesterday from sunny Tromsø for the annual #FramStraitNPI cruise aboard #FFKronprinsHaakon! We'll spend the next 3 weeks at around 79°N in Fram Strait, collecting lots of oceanographic data and samples for the @epocproject.bsky.social and several other projects. Stay tuned for updates!

Our team member Dmitry is onboard @awi.de Polarstern on the #CONTRASTS expedition in the #Arctic Ocean. Part of the work is to deploy a number of autonomous systems to track the movement of the #seaice and how it is melting. Data will be made accessible on the @meereisportal.bsky.social data portal
