NABOS 2023 Cruise
Kodiak, AK to Tromsø, Norway, August 26–October 2
This cruise happens during a time of extraordinary changes in the Arctic. The exceptional magnitude of recent high-latitude changes in the ocean, ice and atmosphere strongly suggests that these changes signify a shift to a new Arctic climate state. This expedition will provide key information about the historical transitions occurring in the Arctic Ocean, and will provide participants a unique opportunity to witness these transitions first-hand.
Cruise goals
- Recover and re-deploy 9 moorings, which have been collecting data since 2021
- Collect more observations of water temperature, salinity, and other chemical parameters

About NABOS
NABOS is part of the Arctic Observing Network. NABOS research is funded by the National Science foundation and the National Oceanic and Atmospheric Administration.
Since the early 2000s, the goal of NABOS has been to compile a cohesive picture of climatic changes in the Eurasian and Makarov basins of the Arctic Ocean. NABOS works to understand:
- how boundary currents transport Atlantic Water
- how Atlantic Water interacts with shelf waters, the deep basin interior, and the upper ocean
- changes in upper ocean circulation within these basins
