Hydrodynamic conditions associated with the formation, maintenance and dissipation of a phytoplankton thin layer in a coastal upwelling system ArchiMer
Velo-suarez, Lourdes; Fernand, Liam; Gentien, Patrick; Reguera, Beatriz.
During May-June 2005, a 17-d cruise was carried out in Ria de Pontevedra (Galician Rias Baixas) to study the physical-biological interactions that may lead to subsurface aggregations of phytoplankton organisms in thin layers (TLs). Physical processes governed the initiation and development, maintenance, and decline of a diatom (toxin producing Pseudo-nitzschia spp. and Chaetoceros socialis) TL during an upwelling relaxation-upwelling-downwelling sequence. Differences in shear profiles appeared to lead to the formation of a TL during upwelling events. These results reveal that the coupling between maximum values of shear and buoyancy frequency can shape a subsurface chlorophyll maximum (SCM) into a TL. The effect of shear upon phytoplankton patches, which...

Variability of circulation features in the gulf of lion NW Mediterranean Sea. Importance of inertial currents ArchiMer
Petrenko, Aa.
ADCP data from two cruises, Moogli 2 (June 1998) and Moogli 3 (January 1999), show the variability of the circulation features in the Gulf of Lion, NW Mediterranean Sea. The objective of the present study is to determine whether the hydrodynamic features are due to local forcings or seasonal ones. During both cruises, the Mediterranean Northern Current (NC) is clearly detected along the continental slope and intrudes on the eastern side of the shelf. East of the gulf, its flux is similar to2 Sv both in June and January in opposition to previous literature results. Otherwise, the NC characteristics exhibit usual seasonal differences. During the summer, the NC is wider (35 km), shallower (similar to200 m), and weaker (maximum currents of 40-50 cm s(-1)) than...
