Abstract

Laboratory experiments have been carried out to help assess and quantify the role of marine phytoplankton in the production of non-methane hydrocarbons. Evidence is presented here that supports the hypothesis that some short-chain hydrocarbons are produced during diatom and dinoflagellate lifecycles. The pattern of their emissions to the air above axenic unicultures of diatoms and dinoflagellates has been followed. The results suggest that ethane, ethene, propane and propene are produced during the autolysis of some phytoplankton, possibly by the oxidation of polyunsaturated lipids released into their culture medium. In contrast, isoprene and hexane appear during phytoplankton growth and are thus most likely produced either directly by the plankton or through the oxidation of exuded dissolved organic carbon.
