Conclusions
Upwelled waters off the Campeche coast are brought to the region recurrently by the southwestward peninsular currents from the Yucatecan coast, hundreds of kilometers away, being stronger during summer (from July to August each year). Although the region is wide open and very shallow, this phenomenon manages to separate the water column into two layers with differentiable thermohaline characteristics, both with Caribbean water-type signatures evidencing the high connectivity of the region.
More information is needed to address these interesting phenomena and improve our understanding of their role in the environment. The following are some of the issues that still remain open and would be interesting to address in future work: (1) the role that upwelled waters must play in the heat budget of the Yucatan shelf, that in spring and summer exhibits high atmospheric temperatures (>35°C). (2) The interaction between these events and the Northerly cold wind burst phenomena, which also cools down the water temperature of the region. (3) The important implications they must have to the marine biota over the bank by bringing colder and nutrient-rich underwaters of Caribbean origin, to mention a few.
