Short summary

We studied seasonal and spatial variations in particle size of Saharan dust deposition along a transect in the Atlantic Ocean, using an array of moored submarine sediment traps. We show a downwind decrease in particle size, but seasonal changes are also prominent. In addition, the dust is much coarser than previously suggested and incorporated into climate models.
