Abstract

Atmospheric fixed-nitrogen deposition can contribute to eutrophication in coastal and estuarine waters. Stable nitrogen isotope data can provide important information regarding the sources and processing of atmospheric fixed-nitrogen species and is thus important in controlling eutrophication. Size-segregated aerosol samples were collected from two coastal sites: Weybourne, England and Mace Head, Ireland and also aboard the RRS Challenger in the Eastern Atlantic Ocean. Aerosol concentrations of ammonium and nitrate were determined prior to d15N isotopic analysis. The isotopic enrichment factor, , was calculated for both the species by subtracting the respective d15N values of the coarse-mode fraction (>1 µm diameter) from those of the fine-mode fraction (
