  1. Phytoplankton Organic Matter Enters Air by Sticking to Ocean Bubbles Bubbles rising through ocean water collect organic matter and transfer it into the sea spray aerosol particles. • Objective • Understand how variations in ocean chemistry affect the enrichment of organics in sea spray particles • Approach • Collect descriptions of chemical properties of organic compounds from the published literature • Collect information about the concentrations of various classes of compounds in different ocean ecosystems • Use the combination of chemical properties and oceanic concentrations to estimate the relative importance of each class of organic compounds in coating bubble surfaces and producing marine spray aerosol • Impact • New analysis allows putting into context different observations of the marine aerosol chemistry from diverse geographic locations, which are affected by different ocean ecosystems • Implementing new insights into future Earth System models will enable greater detail in describing effects of organic compounds on marine clouds.
