NABOS

— at the Atlantic-Arctic frontier since 2002 —

A decades-long effort to build a cohesive picture of climate change in the marine regions of the Siberian Arctic

Established in 2002, NABOS employs a diverse range of observational methods to understand Arctic climate change. NABOS researchers collaborate with scientists from several different countries, collecting vital information to document and understand climatic changes in the Arctic Ocean. The program also encompasses outreach and education through the support of multiple graduate students and shipboard summer schools. Learn more about NABOS

Positions of NABOS moorings since 2021 are indicated by red ovals. In addition, circulation of the surface water (blue), intermediate Pacific Water (PW, pink/blue), and Atlantic water (red) of the Arctic Ocean is shown. Click or tap to enlarge.

About NABOS

NABOS is part of the Arctic Observing Network. NABOS research is funded by the National Science foundation.

Since the early 2000s, the goal of NABOS has been to compile a cohesive picture of climatic changes in the Siberian sector 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, the upper ocean, and sea ice
  • changes in upper ocean circulation within these basins
