The oceans cover 71% of the world and are a large contributor of volatile organic compounds (VOCs) and aerosols. Marine VOCs can be produced from marine microbiology and emitted from the atmosphere to undergo oxidative processing to form secondary marine aerosols (SMA). Dimethyl sulfide (DMS) has been studied extensively because of phytoplankton and bacteria’s ability to produce it in large quantities and because of its ability to form sulfate aerosol and contribute to the earths global radiative budget. However, only studying DMS has left many uncertainties on the contribution of marine VOCs on SMA formation. To better understand the impact of marine VOCs, this dissertation utilized phytoplankton bloom experiments to quantify VOC emissions from seawater and oxidation experiments to assess the role of VOCs on the number, size, and composition of secondary marine aerosols. Throughout this dissertation, dimethyl disulfide (DMDS) was found to be produced in larger quantities than expected and play a significant role in impacting aerosol number concentrations. Overall, this dissertation highlights the importance of other VOCs, with and without sulfur, contributing to the overall composition of the atmosphere.
