The study is focused on the estimation of Lagrangian scales, the calculation of absolute dispersion and the analysis of probability density functions of velocity records. Diffusivity values based on the Lagrangian scales range from 6.9 to 8.8 107 cm2/s. The probability distributions display a non-Gaussian shape with extended tails. It is shown that the long tails are mainly associated with the Campeche gyre (an intense cyclonic circulation frequently formed in the region) and, to a lesser extent, with a flow along the western margin of the basin. The results are discussed in the light of previous studies on ocean dispersion reporting Gaussian and non-Gaussian distributions in other regions.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Se presentan diferentes medidas estadisticas de boyas de deriva superficiales liberadas en el sur del Golfo de México. El estudio se enfoca en la estimación de las escalas Lagrangianas, en el cálculo de dispersión absoluta y en el análisis de las funciones de densidad de probabilidad de los registros de velocidad. Los valores de difusividad basados en las escalas Lagrangianas varían entre 6.9 y 8.8 107 cm2/s. Las distribuciones obtenidas tienen los extremos muy extendidos por lo que no tienen una forma Gaussiana. Se muestra que esta característica está asociada con el giro de Campeche (una circulación ciclónica muy intensa que se presenta con frecuencia en la región) y, en menor medida, con un flujo a lo largo del margen oeste del Golfo. Los resultados se comparan con estudios que han reportado distribuciones Gaussianas y no Gaussianas en otras regiones.]]></p></abstract>
