Submarine Telecommunication Cables as part of the Arctic Ocean Observing System

The Nansen Center participated at the 31st NORDUnet conference held in Reykjavik, Iceland 13-15 September 2022. NORDUnet is a Nordic research and education network (REN) enabling scientists, educators, and students to work and share knowledge globally.


A tiny wooden boat made its way from the Arctic Ocean to the coast of Northern Norway

As part of the Float Your Boat outreach project, hundreds of school children in the US and Norway decorated their own boats in 2020 and 2021. These were set out on top of the floating sea ice in the Arctic, and now the first boat from two years ago has finally made its way back to Norway – to Arnøya at the northernmost part of Norway’s coast.

Smart Ocean 2021 survey cruise with KV Tor

11 students and researchers from NERSC and the University of Bergen participated in a 3-day cruise to Bjørnafjorden south of Bergen and the surrounding area, with the Norwegian Coast Guard vessel KV Tor. The cruise was a part of the SFI Smart Ocean project preparing for a mesoscale observing system using acoustic technology.


Researchers and students working together to collect observations of the ocean and Arctic sea ice

In June, our Acoustic and Oceanography Group organized a research cruise onboard the Norwegian Coast Guard Vessel KV Svalbard. Students and experienced scientists worked side by side to collect sea-ice and oceanographic data. Engagement and involvement are essential to train the new generation of scientists in conducting Arctic field work.

All moorings in the Beaufort Sea rescued – under extreme conditions

The mission to rescue moorings in the Beaufort Sea that had to be planned on short notice, has succeeded! All three moorings hold scientific instruments and data recorded for the CAATEX project since September 2019. They have been picked up by Hanne Sagen, her team, and the KV Svalbard crew under extremely harsh Arctic conditions.


Rescuing important ocean climate observations for the Coordinated Arctic Acoustic Thermometry Experiment (CAATEX)

Once again, the ice breaker KV Svalbard has set course for the Arctic Ocean. Onboard are NERSC researchers Hanne Sagen and Espen Storheim who plan to retrieve equipment from the CAATEX-project to prevent data loss. This mission was planned on short notice – exceptional circumstances made it necessary. 


FyB: Float Your Boat

Float Your Boat vil sette ut 400 trebåter på sjøisen i Arktis for å følge deres bevegelser med vind og havstrømmer fra Polhavet og ut i det Nordiskehavet som en del av skoleundervisning i naturfag.

Formålet med aktiviteten er å øke forståelsen for klimaprosesser, Arktis og betydningen av forskning gjennom aktiv involvering av skoleelever. Prosjektet er basert på Nansensenterets pågående aktivitet i havet nord for Svalbard.
