Dust deposition flux was investigated in lutruwita / Tasmania, Australia, between 2016–2021. Results show that the use of direct measurements of aluminium, iron, thorium, and titanium in aerosols to estimate average dust deposition fluxes limits biases associated with using single elements. Observations of dust deposition fluxes in the Southern Hemisphere are critical to validate model outputs and better understand the seasonal and interannual impacts of dust deposition on biogeochemical cycles.
