The Yucatan Shelf, also known as the Campeche Bank, is situated in a tropical region with an abundant amount of precipitation where the karst nature of its geology causes rainwater to be absorbed by the ground, leaving almost no rivers on its surface overflowing to the sea but to the west of the peninsula. Then, continental freshwater inputs are carried through coastal lagoons and the subsoil, by water holes scattered along the seabed on the northern coast (\citealp{r2002}\citealp{waterhouse2011}\citealp{Enriquez_2013}), causing the salinity in most of the shelf to be influenced mainly by evaporation processes. On the other hand, the oceanographic region that surrounds this bank is very dynamic, to the east, the western arm of the large North Atlantic Anticyclonic Ocean Gyre is found represented by the strong high-speed flow of the Yucatan current. To the north, the Lazo current with its mesoscale eddies are located, and to the west is the Bay of Campeche, identified as a deep-sea area with a semi-permanent cyclonic eddy.  The exchange of properties between the adjacent ocean and the shelf is limited due to the shallowness of the region, however, some very important and known interchanging processes occurring on the northern coast of this bank are the upwelling events (\citealp{1979}\citealp*{FURNAS1987161}\citealp{jl2019}). 
Upwelling phenomena on the Yucatan shelf had always been known to the coastal fishing communities, still, it was until the mid-1960s that these were scientifically reported from hydrographic campaigns (\citealp{jd1966}\citealp{jd1968}\citealp{jd1969}\citealp{rossov1966},  \citealp{ns1968}\citealp{elizarov1971}\citealp*{c1973}\citealp{1979}).  Numerous works have emerged investigating the events themselves and the mechanisms that generate them, managing to conceive different hypotheses (\citealp{jd1966}, \citealp{1979},\citealp*{FURNAS1987161}\citealp{Merino_1997}\citealp{r2016}\citealp{jl2016}\citealt{Jouanno_2018}), nevertheless the subject is still a matter of investigation. Although the Yucatecan coast is parallel to the persistent trade winds of the region, its shallowness does not allow us to describe these phenomena using Ekman's theory itself. The most convincing hypothesis suggests that the Yucatecan upwelling is a phenomenon due to the interaction of the Yucatan current with the bathymetric configuration of the shelf break (\citealp*{FURNAS1987161}\citealp{Merino_1997}\citealt{Jouanno_2018}), which at the east of the Peninsula presents a notch that manages to introduce Caribbean water ~ 250-m deep to the surface, which is then carried through the bottom of the shelf towards the coast where the westward currents, forced by the trade winds, redistribute it along the coast (\citealp{r2016}\citealp{jl2016}).
