This study examines the spatial filtering of energy cascades in an eddy-rich Arctic Ocean model, focusing on the spatial, vertical, and seasonal characteristics of kinetic energy (KE) flux across scales. The KE flux is enhanced in late summer to autumn in areas with seasonal sea ices in the Arctic Ocean, particularly pronounced in the upper 50 meters of the ocean during sea ice melting season. This seasonal variation is closely tied to changes in sea ice cover and how the ocean layers are structured vertically. The inverse energy cascade peaks at smaller scales (near 20 km) in the upper 50 m, whereas deeper waters exhibit maxima at larger scales (around 40 km), aligning with the multi-year seasonal cycle of eddy KE. This study highlights the role of eddies in shaping inverse energy cascades and provides new insights into multiscale energetics and eddy-mean flow interactions in regions influenced by sea ice.
