NABOS Cruise 2021
In September 2021, 27 participants from the United States, Russia, Japan and Denmark embark on a 40-day polar expedition aboard of the Russian research vessel R/V Akademik Tryoshnikov.
International Arctic Research Center's Igor Polyakov is chief scientist on the expedition. Other IARC team members include physical oceanographer Andrey Pnyushkov and graduate students Michael Lundberg and Dolly More.
Together with their international colleagues, they will make many complex observations by recovering and deploying moorings and buoys, and through an extensive CTD (conductivity, temperature, depth) survey.
The ocean, ice and atmosphere measurements from this area of pronounced climate changes will help assess the state of the Arctic Ocean.

The 2018 NABOS Expedition aboard the R/V Akademik Tryoshnikov was carried out under the auspices of the NABOS scientific project, bringing together international research institutions and research programs.
The exceptional magnitude of recent high-latitude changes in the ocean, ice, and atmosphere strongly suggests a potentially irreversible shift in the Arctic Ocean to a new climate state.
These changes have important implications for the Arctic Ocean’s marine ecosystem—especially for those components that depend on sea ice or that have temperature- and stratification-dependent sensitivities or thresholds.
Addressing these and other questions requires careful observations. To these ends, this expedition will provide key information about the historical transitions occurring in the Arctic Ocean.
