Wind-driven upwelling along the continental slope of the Alaskan Beaufort Sea occurs throughout the year and transports water from depth onto the shelf, influencing stratification, nutrient availability, and sea-ice melt. However, the limited spatial coverage of observations has constrained our understanding of this process and prohibited the ability to quantify the resulting shelf-basin fluxes of heat, freshwater, and biogenic material. Using an ultra-high-resolution coupled ice-ocean model, we investigate representative summer and winter upwelling events along the Beaufort shelfbreak. We compare their strength, duration, and recovery and assess their effects on local circulation, water-column stratification, and sea-ice conditions. The summer event produced a shelf-wide mean temperature decrease of ~0.5°C and a salinity increase of ~0.4 PSU. The stronger winter event generated substantially larger hydrographic changes, with temperatures decreasing by ~1.15°C and salinity increasing by ~1.5 PSU. The corresponding shelf-basin fluxes are investigated and their impacts explored.
