Reduction du nitrate dans les sediments marins. Comparaison des activites mesurees in vitro et in situ ArchiMer
Esteves, J; Bonin, P; Blanc, F; Mille, G; Bertrand, J.
In vitro nitrate reduction in hydrocarbon-polluted marine sediments has been studied by flow-through system. By analysing the rate of nitrate comsumption as a function of nitrate concentration the authors determined the Michaelis-Menten kinetics parameters. (km = 330 mu M; vax = 2.0 mu M/g super(-1)/h super(-1). The authors found a value of 60 mu M/m super(-2)/h super(-1) for the rate of in vitro nitrate consumption derived from the above kinetic parameters and from the nitrate concentration in the sediment. In parallel a value of 67.4 mu M/m super(-2)/h super(-1) was found for the rate of nitrate consumption under in situ conditions. The great similarity between both results would favor the in vitro technique as a valid and more convenient one.

Perturbations spatio-temporelles anthropiques sur l'ecosysteme marseillais ArchiMer
Calmet, D; Charmasson, S; Blanc, F.
A chronological analysis of the disturbances caused to a pelagical ecosystem by domestic and industrial outfalls discharged on the surface of the coastal waters is done. Chronological series of various sampled parameters give evidence two fundamental components, a daily one (the trend) and the other one characterized by a periodicity of about 6 h, both linked to the different phases of human activities. Cross spectral analysis applied to salinity and phytoplankton series has pointed out a 50 min delay in the answer of phytoplankton communities to the periodical salinity variations. The use of the spectral principal components analysis allowed a description of the "hydrological" structure of the studied pelagical environment associated with 3 different...

Evolution in data and product management for serving operational oceanography, a GODAE feedback ArchiMer
Blanc, F; Baralle, V; Blower, J.d.; Bronner, E; Cornillon, P; De La Beaujardiere, J; Donlon, C; Gemmel, A; Hankin, S.c.; Keeley, R; Lauret, O; Loubrieu, Thomas; Petiteville, I; Pouliquen, Sylvie; Price, M; Pugh, T; Srinavasan, A.
The GODAE (Global Ocean Data Assimilation Experiment) project has operated for a decade to establish a common definition and description of what is a GODAE ocean data product, and tuned each production center to routinely serve quality-controlled ocean data. A legacy of GODAE has been in harmonizing the various products and the development of essential and generic functions to connect users to products tackling the problem of both the diversity of ocean data and volume of data flows. The European directive 'Infrastructure for Spatial Information in Europe (INSPIRE) and the IOOS Data Management And Communication plan issues (DMAC) have defined the (distributed) architecture to serve data geospatially referenced. Since 2007, the two of them enter the...
