Finally! We are happy to announce that the article on a conceptual modelling toolkit for the pan-Arctic was published in Progress in Oceanography 189, 102455 in late 2020. This article is the result of a productive, inspiring, intense and fun workshop in Solomons, Maryland, some years ago, and took substantial discussion and effort across disciplinary and geographic boundaries, yet eventually resulted in highlighting connectivity rather than boundaries. We define contiguous domains, i.e. regions of unified functions, across the Arctic Ocean, and synthesize how ice cover, food availability and advection act jointly inside each of these functional units. We also highlight how the Arctic Ocean is inherently linked to the global ocean through forcing by its lateral boundaries. Thanks to all contributors.
