Abstract
The behavior of marine currents in the Florida Straits was sampled by seven oceanographic moorings between 2012 and 2018. Using data from one of these moorings, the behavior of the Florida Current during said period was analyzed. The statistical parameters used in the research were: minimum, maximum, mean, standard deviation, anomalous values, and Pearson's correlation coefficient. Current roses were obtained at different depths from the filtered data with a cut frequency of 48 hr-1. The maximum magnitude values of the Florida Current reached up to 2 m/s, with a movement towards the east-northeast or east. Absolute values of the anomalies in the study period 2012 -2018 did not exceed 0.15 m/s, and those of monthly anomalies alternated their sign in a biannual or triannual period. An extremely low linear correlation was detected between annual series for all depths of the analysis, with absolute Pearson correlation values lower than 0.31. Particularly, between August-2013 and August-2014, the Florida Current showed a slight tendency to slow down; and in the period August-2015 // August-2016, a predominance in its proximity to Cuba. No evidence was found of anomalous behavior of the Florida Current with respect to its historical behavior.
