“…Compared with enrichments noted in the equatorial zone during other cruises (Champalbert & Pagano, 2002;Lebourges-Dhaussy et al, 2000; pers. observations), we evidenced some differences, consistent with the temporal hydrological and/or biological variability previously evidenced in the oligotrophic tropical regions (Vinogradov, 1997;Finenko et al, 2003;Piontkovski et al, 2003b) and in the Atlantic equatorial zones (Voituriez et al, 1982;.…”

“…First biological studies concern tuna prey (N' Goran & Pagano, 1999;Lebourges-Dhaussy et al, 2000), copepod feeding (Champalbert & Pagano, 2002) and global plankton biomass (acoustic measurements) in relation with the hydrodynamic features (Menkes et al, 2002). Results showed that zooplankton play an important role as food for tuna preys (N'Goran & Pagano, 1999).…”

“…At night, most micronekton organisms migrate towards the surface layer (e.g. Lebourges-Dhaussy et al 2000), and the few organisms that remain in the intermediate layer form small aggregates. In addition to the usual central eddy pumping mechanism, observational and process-modelling studies have shown an enhancement of primary production and an accumulation of biomass on the edges of anticylonic eddies (Mizobata et al 2002) and at eddy-eddy interactions (Lima et al 2002).…”

“…Prokaryotes dominated phytoplankton as indicated by an abundance of divinyl chlorophylls and zeaxanthine. Zooplankton biomass vertically integrated to 150 meters was sampled by net tows at each station [ Lebourges‐Dhaussy et al , 2000]. An equivalent of zooplankton concentration was also inferred from 150 kHz ADCP backscatter [ Flagg and Smith , 1989] and micronekton biomass from 38 kHz echosounder.…”
