dc.description.abstractThe dynamics of the coloured fraction of dissolved organic matter (CDOM) in marine systems is of high interest because this fraction is optically active. CDOM absorbs UV and visible light and thus affects the pelagic microorganisms in two ways: it reduces the light availability for photosynthesis and diminishes the cell damage induced by UV radiation. Major sources of CDOM are continental runoff and in situ production by microorganisms. Interestingly, Mediterranean waters exhibit exceptionally high values of CDOM to chlorophyll (Chl) ratio when comparing them with those of waters from other marine basins. We, in this study, explored the possible importance of atmospheric material deposition in modulating the amount of the CDOM in an area influenced by anthropogenic aerosols and also by episodic events of Sahara winds, which are associated with high dust deposition rates. To address this question we collected samples for atmospheric deposition (at the roof of the Institute of Marine Sciences (ICM‐CSIC) in Barcelona) and for seawater analyses (at 0.5 km offshore of Barcelona) over a two‐year period (September 2012 ‐ July 2014). We investigate, during this period, the dynamics of CDOM and also of a subfraction of this organic matter, the fluorescent dissolved organic matter (FDOM). Our observations indicate that DOM composition measured with optical techniques varied when Saharan wind events occurred and also evidence an increase in the FDOM flux during these events. We will discuss our findings in relation to organic matter remineralization in surface Mediterranean waters-
