Relevant concentrations of dimethyl- and diethylammonium salts (DMA+ and DEA+) were measured in submicrometer marine aerosol collected over the North Atlantic during periods of high biological activity (HBA) in clean air masses (median concentration (minimum-maximum) ) 26 (6-56) ng m-3). Much lower concentrations were measured during periods of low biological activity (LBA): 1 (
