Última Essai de détermination d'une typologie des sédiments côtiers en fonction de l'apparition d'eaux colorées ArchiMer Arzul, Genevieve; Youenou, A.; Derrien, Annick; Gentien, Patrick; Crassous, M.p.; Lunven, M.. The study of different chemical parameters characterizing the coastal sediment, showed a possible relation between, respectively, high levels in organic matter and total copper, and the "red tide"  phenomenon.

Two expeditions were achieved at the winter-spring transition in the Golfe de Fos (Mediterranean Sea) at a site situated at 21 m depth. An in situ autonomous oxygen profiler and laboratory oxygen mini-electrodes were used to measure the oxygen distribution in the sediments and calculate the diffusive oxygen fluxes. Clearer waters during the second expedition promoted a rapid shift from a net heterotrophic environment to a photosynthesis-dominated sediment. The diffusive exchange fluxes of oxygen through the sediment-water interface varied from an average consumption of 5.3 mmol m(-2) d(-1) (February) to a net production of 12 mmol m(-2) d(-1) (March). At both periods, a large spatial heterogeneity was recorded by the different electrodes, with a larger...
