Data from current meter, hydrographic measurements, and numerical modeling are analyzed to determine the
circulation patterns in the Sistema Arrecifal Veracruzano (SAV), Veracruz, Mexico, region. Results show that the
main forcing in the region is the along-coast wind stress component. Tides contribute with one order of
magnitude less energy, during the fall-winter period. Two main regimes are identified: one between the coast and
the 20 m isobath, with waters of large turbidity and small influence from rivers, and the other between the 20 m
isobath and the external shelf, with clearer waters. Stratified water column with low temperature upwelled waters
near the bottom are observed when southeasterly winds are present. Downwelling and southeastward currents
are associated with northerly winds linked with northers.
