Abstract Eddies play an important role in the regulation of oceanic heat redistribution. This study investigates and analyzes submesoscale eddies in the upper ocean from the edge of the Beaufort Shelfbreak to the southern Canada Basin using data from the MITgcm LLC4320 model, focusing on their spatiotemporal distribution, trajectories, heat content, and variations in anomalous heat content. The results indicate that eddy activity within the jet region exhibits seasonal variation. Eddy counts pea
