Distribución espacial del amonio en fiordos y canales comprendidos entre Puerto Montt y Laguna San Rafael en período de primavera OceanDocs
Prado-Fiedler, R..
An oceanographic expedition was carried out between October 18th and November 15th 1995 in the inlets region and fjords located between Puerto Montt (41° 20’S and San Rafael Lagoon (46° 40’ S) in Southern Chile. The main purpose of the present work is to characterise the spatial distribution of ammonium and its concentration range in the studied region during spring onset. Water samples were collected from a total of 101 oceanographic stations of the expedition Cimar-Fiordo 1. The main part of the water body showed concentrations lower than 1 µmol/L. The higher ammonium concentrations were found in the continental fjords, specially in the area situated south of the narrows of Meninea island, where subsurface maximums greater than 2 µmol/L were found. The...

Evolution de la complexation des metaux (Ca, Mg, Cd, Pb et Cu) dans l''estuaire de la Seine ArchiMer
Fischer, J; Wartel, M.
Interaction between metallic ions and dissolved organic matter can take major part in the biogeochemical cycle of metals in the aquatic environment. The authors point out copper behavior by the study of complexing capacity of surface and bottom waters. A systematic analysis of major elements in natural waters has allowed for a proposal of geographical distribution of metals.

Mineral and organic soluble forms of zinc, iron and copper: Distribution in the Seine Estuary. ArchiMer
Gandon, R; Guegueniat, P; Fischer, J; Wartel, M.
One characteristic of the Seine Estuary system is the process of sediment resuspension by the specific hydrodynamics of this environment. It's the main factor of trace metals transport. Autotrophic activities also have an effect on the estuary, by pH variation. The behavior of soluble and organic copper, iron, have been studied in relation to salinity in and out of the estuary. The results are compared with those of other estuaries.
Tipo: Text Palavras-chave: Hydrodynamics; Physicochemical properties; Water properties; Dissolved organic matter; Biogeochemical cycle; Resuspension; Metals; Suspended particulate matter.

Mise en evidence des profils d'évolution pluariannuelle associés aux series de mesures de parametres hydrobiologiques effectuées dans l'estuaire de la Seine dans le cadre du reseau national d'observation de la qualité du milieu marin ArchiMer
Gallet, P.
The author deals with hydrobiological data obtained monthly by the French marine pollution network. The mathematical analysis gives a representation of ammonium, phosphates, silicate, nitrogen and dissolved oxygen evolution from 1976 to 1983.
Tipo: Text Palavras-chave: Mathematical models; Estuaries; Long term changes; Pollution monitoring; Water quality; Time series analysis; Physicochemical properties; Water properties.

Pouvoir complexant des eaux de l'estuaire de la Seine ArchiMer
Fischer, J; Wartel, M; Guegueniat, P; Gandon, R.
Copper has been studied, by the authors, owing to its ability to complex with various organic ligands of natural waters. Metals extraction and liberation can be explained, in part, by this complexing capacity.
Tipo: Text Palavras-chave: Estuaries; Suspended particulate matter; Dissolved organic matter; Copper; River discharge; Ion association; Metals; Biogeochemical cycle; Water properties.
