The range of surface temperatures is 25.5 to 27.5°C, and the saline surface ranges between 33.2 and 33.8 PSU. The thermocline is located at 20 m at the northern end of the region, while at the southern end, from Ostional up to Guiones, it was observed slightly deeper, approximately 25 m deep. The thickness of the mixed layer was 10 m in virtually all the studied area. Two gyres, one cyclonic and another anticyclonic, were observed in front of Ostional. The surface layers were occupied by the Surface Tropical Water (STW), with salinities below 34 PSU and temperatures greater than 26°C, and the intermediate levels (~ 50 m) by the Subsurface Subtropical Water (SSW), characterized by a saline core near 35 PSU. The bathymetry of the region shows isobaths parallel to the coast, with an elevation close to 20 m deep at the southern end of this area. The degree of inclination did not exceed 14.5°. Entre el 6 y el 11 de febrero del 2012, se realizó un levantamiento hidrográfico y batimétrico en la región situada entre Punta Guiones y Cuajiniquil, en el Pacífico norte de Costa Rica. Las temperaturas superficiales se ubicaron entre los 25.5 y 27.5°C, y el rango salino superficial estuvo entre 33.2 y 33.8 PSU. La termoclina se localizó a los 20 m en el extremo norte de la región, mientras que en el extremo sur, desde Ostional hasta Guiones, se observó ligeramente más profunda, alrededor de los 25 m. El espesor de la capa de mezcla fue de 10 m en toda el área estudiada. Dos giros, uno ciclónico y otro anticiclónico, se registraron en la región frente a Ostional. Los estratos superficiales estuvieron ocupados por el Agua Superficial Tropical (AST), con salinidades inferiores a 34 PSU y temperaturas superiores a 26°C, y los niveles intermedios (~ 50 m), por el Agua Subsuperficial Subtropical (ASS), caracterizada por un núcleo salino cercano a las 35 PSU. La batimetría de la región muestra isóbatas paralelas a la costa, con una elevación alrededor de los 20 m de profundidad en el extremo sur de la zona estudiada. El grado de inclinación o pendientes no sobrepasaron los 14.5°. Entre os dias 6 e 11 de fevereiro de 2012, realizou-se um levantamento hidrográfico e batimétrico na região situada entre Punta Guiones e Cuajiniquil, no Pacífico norte da Costa Rica. As temperaturas superficiais localizaram-se entre 25.5 e 27.5°C, e a faixa salina superficial esteve entre 33.2 e 33.8 PSU. A termoclina localizou-se nos 20 m no extremo norte da região, enquanto no extremo sul, desde Ostional até Guiones, observou-se ligeiramente mais profunda, ao redor dos 25 m. A espessura da capa de mescla foi de 10 m em toda a área estudada. Duas rotações, uma ciclonal e outra anticiclonal, registraram-se na região em frente a Ostional. Os estratos superficiais estiveram ocupados pela Água Superficial Tropical (AST), com salinidades inferiores a 34 PSU e temperaturas superiores a 26°C, e os níveis intermediários (~ 50 m), pela Água Subsuperficial Subtropical (ASS), caracterizada por um núcleo salino próximo às 35 PSU. A batimetria da região mostra isóbatas paralelas à costa, com uma elevação ao redor dos 20 m de profundidade no extremo sul da zona estudada. O grau de inclinação ou declive não ultrapassaram 14.5°.
