  abstract = {{T}his study investigates the circulation on the {F}rench {G}uiana continental shelf under tidal influence. {I}ndeed, hydrodynamics are characterised by a weak salinity tongue located in the middle of the shelf and induced by the {A}mazon {R}iver, a coastal current flowing from the southeast, and a tidal standing wave whose co-range lines are parallel to the coast. {I}n addition to field observations, a numerical model also is used to evaluate the tidal influence on coastal circulation. {T}he model makes use of the {MOBEEHDYCS} code, a three-dimensional free surface time-splitting model whose domain is bounded with a closed coastal boundary, two active boundaries (offshore and lateral) and a passive boundary. {T}he boundary configuration and hydrodynamics require a careful choice of passive open boundary conditions. {T}he initial and boundary conditions come from field data. {T}he tidal currents are essentially cross-shore and do not have a great influence on the main current direction on the offshore part of the shelf. {T}he offshore currents remain parallel to the coast. {I}n the inner shelf, the tidal influence is found to be much more important and the tidal currents can reach 0.45 m/s. {V}ertically, the tidal currents are barotropic, in spite of the high stratification and they induce a horizontal cross-shore migration (about 3 km) of the weak salinity tongue and vertical oscillations of the halocline without complete mixing.},
