Última Mesoscale slope current variability in the Gulf of Lions. Interpretation of in-situ measurements using a three-dimensional model ArchiMer Andre, Gael; Garreau, Pierre; Fraunie, Philippe. The ECOLOPHY experiments aimed at investigating physical exchanges between coastal and open sea. They were carried out in June and December 2005 over the shelf-break in the North-eastern part of the Gulf of Lions (Northwestern Mediterranean Sea). This area is considered to be the generation zone for the eddy and meandering structures of the Northern Current (NC). The objective of the present work is to examine mesoscale variability of this coastal slope current in the light of available data. Numerical modeling is used to support the field data analysis. ADCP current measurements over a one-year period show that mesoscale activity is maximal in late winter, correlating with the seasonal variability of the NC and, also, partly with local winds, Measured...

Ano: 2009 URL: http://archimer.ifremer.fr/doc/2009/publication-6461.pdf Prospects for Future Satellite Estimation of Small-Scale Variability of Ocean Surface Velocity and Vorticity ArchiMer Chelton, Dudley B.; Schlax, Michael G.; Samelson, Roger M.; Thomas Farrar, J.; Jeroen Molemaker, M.; Mcwilliams, James C.; Gula, Jonathan. Recent technological developments have resulted in two techniques for estimating surface velocity with higher resolution than can be achieved from presently available nadir altimeter data: 1) Geostrophically computed estimates from high-resolution SSH measured interferometrically by the wide-swath altimeter on the Surface Water and Ocean Topography (SWOT) Mission with a planned launch in 2021; and 2) Measurements of ocean surface velocity from a Doppler scatterometer mission that is in the early planning stages, referred to here as a Winds and Currents Mission (WaCM). In this study, we conduct an analysis of the effects of uncorrelated measurement errors and sampling errors on the errors of the measured and derived variables of interest (SSH and...

Ano: 2019 URL: https://archimer.ifremer.fr/doc/00461/57290/59365.pdf Improved description of the ocean mesoscale variability by combining four satellite altimeters - art. no. L02611 ArchiMer Pascual, Ananda; Faugere, Yannice; Larnicol, Gilles; Le Traon, Pierre-yves. Data from four satellite altimeters are combined with the aim of improving the representation of the mesoscale variability in the Global Ocean. All missions [Jason-1, ERS-2/ENVISAT, Topex/Poseidon interleaved with Jason-1 and Geosat Follow-On] are cross-calibrated previously to produce weekly gridded maps. In areas of intense variability, the rms differences between a classical configuration of two altimeters and the scenario merging four missions can reach 10 cm and 400 cm(2)/s(2) in SLA and EKE, respectively, which represents an important percentage of the signal variance. A comparison with surface drifters shows that the four altimeter scenario improves the recovery of mesoscale structures that were not properly sampled with Jason(-1) + ERS-2/ENVISAT....

Ano: 2006 URL: http://archimer.ifremer.fr/doc/2006/publication-1038.pdf Variabilité hydrologique et biologique du golfe du Lion. I. Transports en azote et productivité potentielle ArchiMer Conan, P; Pujo-pay, M; Raimbault, P; Leveau, M. A monthly time-series of the seasonal evolution of the North Mediterranean Current (NMC) and of nitrogen flux across a transect (5 degrees 12'5 E between 43 degrees 10'N and 42 degrees 50'N) at the entrance of the Gulf of Lions was carried out over two years. The NMC exhibited two distinct structures: a winter structure (from November to May) characterised by strong mesoscale and interannual variations in which the current was 20 to 30 km width, about 400 m depth and velocity scaled between 5 and more than 40 cm s(-1); and a summer structure (from May to November) which was less sensitive to mesoscale variations but showing large interannual variability. The current was located more offshore, was wider and shallower than the one in winter and velocity...
