  abstract = {{C}irculation and the related biological production have been studied during five cruises conducted in the {M}ozambique {C}hannel ({MZC}) between 2005 and 2010. {T}he circulation in the {MZC} is known to be highly turbulent, favouring enhanced primary production as a result of mesoscale eddy dynamics, and connectivity throughout the {C}hannel due to the variable currents associated with migrating eddies. {T}his paper presents the results of in situ measurements that characterize the horizontal and vertical currents in the surface and subsurface layers (0-500 m). {T}he in situ data were analysed together with the geostrophic eddy field observed from satellite altimeter measurements. {D}ifferent circulation regimes were investigated, including the "classical" anticyclonic eddy generated at the {C}hannel narrows (16 {S}), the enhancement of southward migrating eddies by merging with structures (both cyclonic and anticyclonic) formed in the east of the {C}hannel, and the presence of a fully developed cyclonic eddy at the {C}hannel narrows. {C}omparison between in situ measurements ({S}-{ADCP} and velocities derived from surface drifters) and the geostrophic current derived from sea surface height measurements indicated that the latter can provide a reliable, quantitative description of eddy driven circulation in the {MZC}, with the exception that these currents are weaker by as much 30%. {I}t is also suggested from in situ observation (drifters) that the departure from geostrophy of the surface circulation might be linked to strong wind conditions. {F}inally, our observations highlight that a-geostrophic currents need to be considered in future research to facilitate a more comprehensive description of the circulation in this area.},
