DIAZ-FLORES, Miguel Ángel; SALAS-DE-LEON, David Alberto  and  MONREAL-GOMEZ, María Adela. Origin and evolution of cyclonic eddy of the Bay of Campeche, Gulf of Mexico. Rev. biol. mar. oceanogr. [online]. 2017, vol.52, n.3, pp.441-450. ISSN 0718-1957.

The ocean is characterized by a circulation dominated by vortex of different sizes; the vortex play a very important role in the oceanic climate as they transport energy, mass and organisms. Their study is therefore of first importance to understand the different processes that occurring in the seas at different time-space scales. The Bay of Campeche, in the southern Gulf of Mexico, is characterized by a cyclonic circulation. With the aim of identifying the origin and the formation of the cyclonic vortex, data of currents registered in an oceanographic survey and data of sea altimetry obtained with remote sensors were analyzed. From the results, the formation of the cyclonic vortex of the Bay of Campeche depends mainly on the conservation of the potential vorticity.

Keywords : Potential vorticity; cyclonic eddies; circulation in bays; altimetry.
