[{"name":"zinke-2024-baltic-bioaerosols-1","title":"Measurements of bioaerosols, bacteria and ionic composition in sea spray aerosols from experiments in the Baltic Sea","summary":"Measurements of bioaerosols, bacteria and ionic composition in sea spray aerosols from sea spray chamber experiments with seawater from the Baltic Sea.\r\n\r\nThe measurements include bacteria enumeration and ionic composition. The bacteria cell counts from aerosol filters and seawater samples were obtained from fluorescence microscopy of 4',6-diamidino-2-phenylindole (DAPI) stained cells. The ionic composition were obtained from ion chromatography of the chamber aerosol and seawater samples. The data further comprises concentration estimates of coarse particles, fluorescent particles and fluorescent primary biological aerosol particles (fPBAP) obtained from multiparameter bioaerosol spectrometer (MBS) measurements.\r\n\r\nThe data is used to investigate the emissions of primary biological particles and bacteria with sea spray aerosols from the Baltic Sea.\r\n\r\nThe measurements were conducted during two ship based campaigns onboard research vessels Oceania and Electra in the proximity of \u00d6stergarnsholm island in the Baltic Sea in May and August 2021.","citations":"","comments":"Attached to the chamber aerosol filter samples were collected for bacteria enumeration and ionic composition analysis. Additionally, continuous measurements were conducted of coarse particles (with diameters >0.8 \u00b5m), fluorescent particles and fluorescent primary biological aerosol particles (fPBAP) using a multiparameter bioaerosol spectrometer (MBS). These measurements were conducted both connected to the sea spray simulation chamber as well as on ambient air. Furthermore, bulk seawater samples and surface microlayer samples were collected.","category":"Atmosphere","subcategory":"Aerosols","keywords":"Sea spray aerosols; Primary biological aerosols; Bacteria; Emission fluxes; Baltic Sea; Research vessel Electra","scientist":"Julika Zinke, Gabriel Freitas, Rachel A.
