   Abstract Arctic Ocean surface circulation change should not be viewed as the strength of the anticyclonic Beaufort Gyre. While the Beaufort Gyre is a dominant feature of average Arctic Ocean surface circulation, empirical orthogonal function analysis of dynamic height (1950–89) and satellite altimetry–derived dynamic ocean topography (2004–19) show the primary pattern of variability in its cyclonic mode is dominated by a depression of the sea surface and cyclonic surface circulation on the Russian side of the Arctic Ocean. Changes in surface circulation after Arctic Oscillation (AO) maxima in 1989 and 2007–08 and after an AO minimum in 2010 indicate the cyclonic mode is forced by the AO with a lag of about 1 year. Associated with a one standard deviation increase in the average AO starting in the early 1990s, Arctic Ocean surface circulation underwent a cyclonic shift evidenced by increased spatial-average vorticity. Under increased AO, the cyclonic mode complex also includes increased export of sea ice and near-surface freshwater, a changed path of Eurasian runoff, a freshened Beaufort Sea, and weakened cold halocline layer that insulates sea ice from Atlantic water heat, an impact compounded by increased Atlantic Water inflow and cyclonic circulation at depth. The cyclonic mode’s connection with the AO is important because the AO is a major global scale climate index predicted to increase with global warming. Given the present bias in concentration of in situ measurements in the Beaufort Gyre and Transpolar Drift, a coordinated effort should be made to better observe the cyclonic mode.

5. Strategy for Protecting the Future Arctic Ocean

   https://doi.org/10.5670/oceanog.2022.131  

   Brigham, Lawson; Gamble, James (January 2022, Oceanography)

   Marine access in the Arctic Ocean is increasing due to the relentless retreat of sea ice driven by anthropogenic climate change. Longer seasons of marine navigation allow increasing marine use by a diversity of stakeholders and vessels. Progress has been made in protecting the Arctic Ocean through cooperation among the Arctic States and proactive advances within international organizations, notably the International Maritime Organization. Measures addressing Arctic marine safety and environmental protection have been developed and adopted. This paper reviews 12 strategies or pathways forward for implementing policy measures developed in an array of organizations to protect the future Arctic Ocean. Ten high priority recommendations, all near-term action items that are believed achievable, are also advanced toward protecting Arctic people and the marine environment in the twenty-first century.
