  2. 1. Submicrometre aerosol emissions from sea spray and road traffic

    Author : Monica Mårtensson; Douglas Nilsson; Christer Johansson; Michael Smith; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Eddy covariance method; aerosol emissions; submicrometre sea salt parameterisation; primary marine organic aerosols; sea spray; road traffic emission factors; air-sea exchange; aerosol dynamics model; internal aerosol mixing; combustion aerosols; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

    Abstract : The uncertainty of the climate and health effects of aerosols is still large, one important reason being lack of knowledge of the primary emissions. This thesis combines laboratory and field experiments, and process modelling in an effort to better quantify the submicrometre aerosol emissions and to understand some of the processes in the atmosphere.

  4. 2. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies

    Author : Julika Zinke; Matthew E. Salter; Paul Zieger; Rachel A. Foster; E. Douglas Nilsson; Patricia K. Quinn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sea spray aerosols; eddy covariance fluxes; air-sea-exchange; bacteria; primary biological airborne particles; laboratory studies; field studies; Baltic Sea; North-Eastern Atlantic; Environmental Sciences; miljövetenskap;

    Abstract : Sea spray aerosol (SSA) is one of the major natural aerosol sources and is produced when wave breaking entrains air into ocean surface water, which subsequently breaks up into bubbles. These bubbles rise to the surface and can scavenge biogenic material. READ MORE

  5. 3. Enrichment of biogenic and anthropogenic organic substances on sea spray aerosols

    Author : Nikola Radoman; Ian Cousins; Matthew Salter; Jurgita Ovadnevaite; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sea spray; Organic carbon; Dissolved organic matter; Phytoplankton bloom; Cationic surfactants; Perfluorinated alkyl acids; LC-MS; HRMS; Analytical Chemistry; analytisk kemi;

    Abstract : The world’s oceans are the source of one of the most abundant types of natural aerosols, namely sea spray aerosols (SSA). By scattering solar radiation, SSA play a significant role in controlling the Earth’s radiation budget, while they are also involved in the formation of clouds, acting as cloud condensation nuclei (CCN).

  6. 4. On mechanisms controlling air-sea gas exchange

    Author : Lucía Gutiérrez-Loza; Anna Rutgersson; Erik Sahlée; Marcus B. Wallin; Tom Bell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air-sea gas exchange; eddy covariance; gas transfer velocity; Baltic Sea; Meteorologi; Meteorology;

    Abstract : Carbon is essential to the Earth’s system functioning, playing a major role in physical and biogeochemical processes in the atmosphere, the terrestrial biosphere, and the oceans. The concentration of carbon-based greenhouse gases in the atmosphere, such as carbon dioxide (CO2) and methane (CH4), has been increasing since the industrial era. READ MORE

  7. 5. Transport of perfluoroalkyl acids from the ocean to the atmosphere via sea spray aerosol

    Author : Bo Sha; Ian Cousins; Matthew Salter; Jana Johansson; Jonathan P. Benskin; Cora Young; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perfluoroalkyl acids; PFAAs; Per- and polyfluoroalkyl substances; PFAS; atmospheric transport; sea spray aerosol; industrial sources; Environmental Sciences; miljövetenskap;

    Abstract : Perfluoroalkyl acids (PFAAs) are a subgroup of per- and polyfluoroalkyl substances (PFAS) that have been widely used in commercial and industrial applications. PFAAs are very persistent in the environment and some can bioaccumulate and have adverse health effects on human health. READ MORE
