Seasonal variability of the temperature and salinity fields in the coastal zone of the states of Jalisco and Colima, Mexico

Seasonal variability of the temperature and salinity fields in the coastal zone of the states of Jalisco and Colima, Mexico

 The results of the analysis of data obtained from a series of oceanographic surveys conducted in an ecological monitoring polygon on the continental shelf off Jalisco and Colima (Mexico) are presented. The surveys were conducted monthly between 1995 and 1997 with an undulating CTD. In one...

The surveys were conducted monthly between 1995 and 1997 with an undulating CTD. In one day, up to 100 soundings were made at stations with a maximum depth of 150 m, in a spatial grid of points with an area of 50 · 15 km. The vertical profiles of temperature and salinity were obtained by averaging the data from the oceanographic surveys. It is shown that the vertical distributions and hydrophysical characteristics analyzed present a significant seasonal variability related to the annual variations of solar energy input and variability of evaporation, precipitation and coastal discharges in the study area. The seasonal oscillations cover a water layer greater than 100 m, but the subsurface layers of the coastal waters are observed with greater intensity.

Se presentan los resultados del análisis de datos obtenidos por una serie de levantamientos oceanográficos realizados en un polígono de monitoreo ecológico en la plataforma continental de los estados de Jalisco y Colima (México). Los levantamientos se llevaron a cabo mensualmente de 1995 a 1997 utilizando un CTD ondulante. En menos de un día se realizaron hasta 100 sondeos en estaciones con profundidad máxima de 150 m, en una malla espacial de puntos que abarca una superficie de 50 x 15 km. Los perfiles verticales de temperatura y salinidad se obtuvieron promediando los datos de los levantamientos oceanográficos. Se muestra que las distribuciones verticales de las características hidrofísicas analizadas presentan una variabilidad estacional significativa relacionada con las variaciones anuales del ingreso de energía solar, variabilidad de la evaporación, precipitación y descargas costeras en la región de estudio. Las oscilaciones estacionales abarcan una capa de agua superior a los 100 m, pero se observan con mayor intensidad en las capas subsuperficiales de las aguas costeras. Los perfiles medios presentan una alta confiabilidad estadística, ya que se suprimieron totalmente las influencias deformantes ocasionadas por las ondas internas.
