Abstract Climate change in the Arctic has substantial impacts on human life and ecosystems both within beyond Arctic. Our analysis of CMIP6 simulations shows that some climate models project much larger than other models, including changes sea ice, ocean mixed layer, air‐sea heat flux, surface air temperature wintertime. In particular, dramatic enhancement Ocean convection down to a few hundred meters is projected these but not others. Interestingly, employ same model family (NEMO) while choice for atmosphere ice varies. The magnitude proportional strength increase poleward transport, which considerably higher this group models. Establishing plausibility with high sensitivity anthropogenic forcing imperative given implied ramifications.

Abstract Ocean eddies play a critical role in climate and marine life. In the rapidly warming Arctic, little is known about how ocean eddy activity will change because existing models cannot resolve Arctic mesoscale eddies. Here, by employing next-generation global sea ice–ocean model with kilometre-scale horizontal resolution we find surge of kinetic energy upper Ocean, tripling on average four-degree-warmer world. The driving mechanism behind this an increase generation due to enhanced baroclinic instability. Despite decline ice, killing (a process which are dampened ice winds) not weaken its annual mean effect considered scenario. Our study suggests importance adequately representing for understanding impacts ecosystems.

We find that monthly, annual, interannual EKE near surface predominantly influenced sea ice cover, while activity deeper depth, being shielded from ocean stratification, more strongly local baroclinic conversion. Moreover, our research demonstrates Basin can transport heat Atlantic Water layer toward cause basal melting order about 20 cm per month even wintertime.

The Arctic Ocean is facing dramatic environmental and ecosystem changes. In this context, an international multiship survey project was undertaken in 2020 to obtain current baseline data. During the survey, unusually low dissolved oxygen acidified water were found a high-seas fishable area of western (Pacific-side) Ocean. Herein, we show that Beaufort Gyre shrinks east ocean ridge forms front between within gyre from eastern (Atlantic-side) Arctic. That phenomenon triggers frontal northward flow along ridge. This likely transports toward area; similar biogeochemical properties had previously been observed only on shelf-slope north East Siberian Sea.
