Diverging sea ice
WebApr 6, 2024 · Article Abstract. Our understanding of Arctic sea ice and its wide-ranging influence is deeply rooted in observation. Advancing technologies have profoundly improved our ability to observe Arctic sea ice, document its processes and properties, and describe atmosphere-ice-ocean interactions with unprecedented detail. WebSep 1, 2024 · For example, high sea ice turning angles increase divergent ice motion in the interior, transporting more ice away from the coast and permitting more ocean–atmosphere heat exchange. Greater advection and divergent motion assist sea ice retreat by dispersing and moving the ice northwards to warmer latitudes.
