Resumen del producto

Oceanic fronts are relatively narrow areas where horizontal gradients of physical, chemical and biological properties, delineate boundaries between different types of surface water. Oceanographic studies in the North Atlantic indicate that some commercial species spawn on the continental shelf, and the eggs and larvae are advected towards fronts with high primary production. In the Gulf of California don't have been studies on the coupling of the associations between fish larvae and front structures. The objective of this work is to implement algorithms to identify and characterize structures of temperature fronts in the Gulf of California and their spatial variability in specific periods from daily satellite images of the sea surface temperature, and develop algorithms to establish spatial relationships between sampling stations and thermal fronts. With the implemented procedure 2,807 thermal fronts regions were detected from February 25 to March 12 (years 2010-2014). The thermal fronts detected by the procedure described in this paper were consistent with the location of mesoscale structures described by other authors for the study area.
