Linkages among halocline variability, shelf-basin interaction, and wind regimes in the Beaufort Sea demonstrated in pan-Arctic Ocean modeling framework

► Basin freshwater increases in phase with wind-driven deepening of halocline layers. ► Basin cyclonic wind enhances Ekman downwelling north of shelf-basin boundary. ► Basin cyclonic wind enhances northeastward transport of fresh Pacific summer water. ► Both Pacific summer water and Ekman forcing contribute to offshore stratification. ► Penetration of Pacific winter water prevents local upwelling north of Barrow Canyon.
