Project description
VOC emissions in the marine environment
Volatile organic compounds (VOCs) are low molecular weight molecules with high vapour pressure, important for atmospheric chemistry as ozone precursors. While terrestrial VOC emissions are well estimated, marine emissions remain poorly understood due to limited data and variability. Supported by the Marie Skłodowska-Curie Actions programme, the MaRVOC project will investigate VOC emissions in marine environments, focusing on biotic interactions. It will identify organisms producing VOCs and the factors influencing their emissions. The project will combine mass spectrometry-based VOC analysis with advanced molecular techniques to explore interactions, taxa, and genes involved in marine VOC production through mesocosm and field experiments. This research aims to address critical knowledge gaps and improve our understanding of marine biogeochemical cycles.
Objective
Volatile organic compounds (VOCs) are diverse bioactive molecules of low molecular weight and high vapor pressure. VOCs are produced by biotic and abiotic processes and are important for atmospheric chemistry as main biogenic precursors of ozone, which is a toxic and potent greenhouse gas. In terrestrial ecosystems, a total emission of 760 Tg (C) yr−1 is estimated from terrestrial vegetation and more than 30.000 VOCs that are released from plants through secondary metabolism pathways have been identified. These VOCs also have great impact acting as inhibitors/stimulators of growth, as protectors against herbivores and pathogens, and as signal molecules in internal and external communication. Despite that the oceans cover 70 % of the Earth’s surface, the emission processes of VOCs from the marine environment are still unknown. The VOC emission from the ocean is very difficult to estimate because data are sparse and rates are highly variable, depending strongly on the abundance and species of phytoplankton, biotic interactions and sinks of these compounds. The aim of this proposed project is to study the biology behind VOC emissions in marine environments and in particular address the importance of biotic interactions: This includes the specific organisms producing these compounds, under what circumstances, and how specific interactions influence VOC emissions. This proposal will for the first time combine novel mass spectrometry-based methods for VOC analysis with cutting edge molecular methods to identify interactions, taxa and functionalities (genes) involved in marine VOC production from mesocosm, phytoplankton-bacteria interactions experiments and fieldwork. I will carry out this research with the supervisors, Prof. Lasse Riemann and Prof. Riikka Rinnan at the Center for Volatile Interactions (VOLT) Centre of Excellence at Copenhagen University. Over the proposal, I will acquire new expertise in molecular biology and VOC analysis by ion mass spectrometry.
