Última Comparison of spaceborne measurements of sea surface salinity and colored detrital matter in the Amazon plume ArchiMer Fournier, Severine; Chapron, Bertrand; Salisbury, J.; Vandemark, Douglas; Reul, Nicolas. Large rivers are key hydrologic components in oceanography, particularly regarding air-sea and land-sea exchanges and biogeochemistry. We enter now in a new era of Sea Surface Salinity (SSS) observing system from Space with the recent launches of the ESA Soil Moisture and Ocean Salinity (SMOS) and the NASA Aquarius/Sac-D missions. With these new sensors, we are now in an excellent position to revisit SSS and ocean color investigations in the tropical northwest Atlantic using multi-year remote sensing time series and concurrent in situ observations. The Amazon is the world's largest river in terms of discharge. In its plume, SSS and upper water column optical properties such as the absorption coefficient of colored detrital matter (acdm) are strongly...

The presence and geochemical behaviour of herbicides were investigated in estuarine and marine waters of the French coasts (Seine, Charente, Gironde estuaries and Rhône delta). These organic contaminants were quantified by capillary Gas Chromatography (GC) using Nitrogen-Phosphorus Detecter and identified by GCIMS (Mass Spectrometry). A liquid-solid extraction method using XAD-2 resins was developed,  allowing the analysis of both chloro-triazines and their degradation products in the nanogram per litre (ng.l-1) detection range. Different types of chemicals were identified in the estuarine and coastal waters: triazine, amide and acetanilide herbicides. These compounds are mainly present in the water phase, with less than 1% associated with particulate...
