Seasonal and interannual variability in the biogenic particle sinking fluxwas recorded using multi-year bottom-tethered sediment trap mooring systemsin the Northwind Abyssal Plain (Station NAP: 75° N, 162° W,1975 m water depth) of the western Arctic Chukchi Borderland. Trappedparticle flux at a median depth of 184 m had an obvious peak and dominanceof sea ice-related diatom assemblages in August 2011. The observed particleflux was considerably suppressed throughout summer 2012. In the presentstudy, the response of ice algal production and biomass to wind-drivenchanges in the physical environment was addressed using a pan-Arctic seaice–ocean modeling approach. A sea ice ecosystem with ice algae was newlyincorporated into the lower-trophic marine ecosystem model, which waspreviously coupled with a high-resolution (i.e., 5 km horizontal grid size)sea ice–ocean general circulation model. Seasonal model experiments covering 2-year mooring periods indicated that primary productivity of ice algaearound the Chukchi Borderland depended on basin-scale wind patterns viavarious processes. Easterly winds in the southern part of a distinctBeaufort High supplied nutrient-rich water for euphotic zones of the NAPregion via both surface Ekman transport of Chukchi shelf water and verticalturbulent mixing with underlying nutricline water in 2011. In contrast,northwesterly winds flowing in the northern part of an extended SiberianHigh transported oligotrophic water within the Beaufort Gyre circulationtoward the NAP region in 2012. The modeled ice algal biomass during summerreflected the differences in nutrient distribution. The modeled sinking fluxof particulate organic nitrogen (PON) was comparable with the time seriesobtained from sediment trap data in summer 2011. In contrast, lateraladvection of ice algal patches of shelf origin during a great cyclone eventmay have caused a modeled PON flux bias in 2012. Sensitivity experimentsrevealed several uncertainties of model configurations of ice algalproductivity, particle sinking speed, and grazing activities. Extending theyear-long measurements is expected to help illustrate the more generalfeatures of ice-related biological processes in the Arctic Ocean
