Turbulent nutrient fluxes in the Iceland Basin

► Turbulent nutrient fluxes are measured around an eddy-dipole in the Iceland Basin. ► Turbulent diffusivity around the dipole has an almost uniform horizontal distribution. ► Macro-nutrient turbulent flux is estimated as up to 14% of deep-winter mixing supply. ► Dissolved iron turbulent flux is estimated as ∼8% of deep-winter mixing supply.
