| Three cruises on the Wight-Cherbourg transect were undertaken during the FluxManche II Programme in order to study the origin, nature and behaviour of organic matter inputs to the waters of the English Channel. Suspended particulate material (SPM) collected from surface and deep waters at each station was analysed at elemental level for Particulate Organic Carbon and Particulate Organic Nitrogen (POC, PON), at molecular level for main classes of organic compounds using Pyrolysis-Gas Chromatography coupled with Mass Spectrometry (Py-GC-MS) and for phenolic compounds, particularly lignin-derived phenols, using High Performance Liquid Chromatography (HPLC). The SPM content increases from the French (south) to the English coast (north) with the lowest values... |

| Within the framework of the multi-disciplinary program Seine Aval, phenolic compounds obtained by CuO oxidation have been studied since 1995. Quantitative analyses have shown a terrestrial contribution in flood, characterized by compounds of the group P (polyols + phenol), S (syringic) and H (hydroxybenzoic). During the low water period, phenolic compounds allow a clear distinction between fluvial and estuarine suspended material. Fluvial run-off contained Syringic, Hydroxybenzoic and Vanillic phenols. In contrast, upstream penetrating marine and estuarine waters are characterized by cinnamic phenols originating from estuarine herbus. In the turbidity maximum zone, aerobic degradation of lignin material increases the (vanillic acid/vanillin) ratio. |
