- Spatial and temporal distribution of sea turtles related to sea surface temperature and chlorophyll- a in Mexican Central Pacific waters Karen M. Zepeda-Borja Christian D. Ortega-Ortiz Ernesto Torres-Orozco Aramis Olivos-Ortiz Ciencias de la Tierra upwelling Sea turtles distribution cyclonic gyre oceanographic parameters In this study we describe the spatial and temporal distribution of sea turtles and their associa tion with oceanographic parameters in waters of the Mexican Central Pacific (MCP) during 2010 (winter, spring and autumn). O ur results showed variations in sea turtle distribution through the sampling year. Sea turtle distribution was homogeneous in coa stal and oceanic areas during winter; there was an association with thermal fronts generated by a current of cold water flowing fr om the northwest and a warm current coming from the south, as well as with the boundaries of a cyclonic gyre. Sea turtles were d istributed in the coastal zone and the central part of the oceanic zone in spring, where the effects of a cyclonic gyre and coastal upwelling prevailed. The same distribution trend was recorded at the beginning of autumn, whereas oceanographic characteristics ch anged during the second sampling week, when upwelling occurred. Mating events were only recorded in autumn for olive ridley sea turtles ( Lepidochelys olivacea ), the dominant species in the region. It was concluded that sea turtles were distributed in the coa stal zone of MCP waters in autumn due to reproductive activities, whereas in winter and spring sea turtles were distributed towards the central/oceanic region, potentially related to foraging activities. 2017 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47952503016 en http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.2 Vol.52
