Dissoled organic compounds with synchronous dynamics share chemical properties and origin (case study Helgoland) and ICBM Ocean
The temporal dynamics of dissolved organic matter (DOM) are inherently linked with the functioning of aquatic ecosystems. Because DOM represents a complex mixture of millions of different compounds, the statistical analysis of DOM dynamics poses a huge challenge. Here, we present results of a recent study using a statistical approach that groups DOM compounds with synchronous dynamics. We applied this approach to time series of Fourier-transform ion cyclotron resonance mass spectrometry data of DOM sampled over a period of 26 months near Helgoland, an island in the Southern North Sea.
Further, the talk will present a new and publicly available tool (ICBM-OCEAN) to process Fourier-transform ion cyclotron resonance mass spectrometry data combining noise elimination, spectral alignment and formula attribution.
