Short summary
Inorganic nitrogen has a great impact on marine productivity when deposited to the ocean via atmospheric deposition. Do dust events always increase the atmospheric input of inorganic nitrogen to the ocean? The estimated deposition flux of NNH4++NO3- varied greatly from event to event. A simple assumption of a linear increase in inorganic nitrogen with increasing dust load could lead to a considerable overestimation of the dry deposition flux of nutrients into the oceans.
