Última Simultaneous use of strontium:calcium and barium:calcium ratios in otoliths as markers of habitat: Application to the European eel (Anguilla anguilla) in the Adour basin, South West France ArchiMer Tabouret, Helene; Bareille, G.; Claverie, F.; Pecheyran, C.; Prouzet, Patrick; Donard, O. F. X.. Sr:Ca and Ba:Ca ratios in water from the Adour estuary show a clear relationship with the salinity of the surrounding water for salinities <20, while ratios are almost constant above this level of salinity. A Positive relationship was observed for the Sr:Ca ratio, whereas it was inverse for the Ba Ca ratio. These two elemental ratios were measured in the otoliths of the European eels (Anguilla anguilla L) using femtosecond laser ablation linked to an ICP-MS (fs-LA ICP-MS) There was a direct relationship between the elemental ratios recorded in eel otoliths and those found in water from fresh and marine areas, suggesting that Sr Ca and Ba:Ca ratios in eel otoliths can be used as markers of habitat in this estuary Continuous profiling allowed the...

Strontium and barium incorporation into otoliths was compared between whitemouth croaker, Micropogonias furnieri, collected from an entrapped freshwater population (Mirim Lagoon) and a normal marine/estuarine population in southern Brazil. Chemical analysis was performed using LA-ICPMS with the objective of validating the effects of marine and freshwater environments on Sr and Ba incorporation as a basis for further investigation of marine and freshwater connectivity of M. furnieri. The freshwater population was dominated by older fish with mean ±SD age of 34±1 y, whereas the coastal samples were dominated by younger fish of 14±7 y. Comparison of strontium and barium incorporation among otolith life-history profiles indicated significantly higher barium...

Ano: 2010 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1679-62252010000200009 Discrete suspended particles of barite and the barium cycle in the open ocean OMA Dehairs, F.A.; Chesselet, R.; Jedwab, J.. Barite particles are a universal component of suspended matter in the Atlantic and Pacific Oceans. This is demonstrated by scanning electron microscope and electron microprobe analyses of samples collected during the GEOSECS program. These discrete particles, about 1 µm in diameter, account for by far the greatest part of the total particulate barium of most of the filters collected at different depths. Total particulate barium (mean value: 20 ng/kg seawater) was measured on the same filters by instrumental neutron activation analysis.Several observations indicate that biochemical, rather than purely chemical, processes are involved in the formation of the BaSO4 mineral in the water column. Sr/Ba molar ratios among the individual barite grains,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Barite; Barium.
