In August and November 2012, two hydrographic surveys were conducted in the coastal region of the Southern Caribbean of Costa Rica, between the Port of Limon and Gandoca Lagoon. A CTD (conductivity, temperature and depth profiler) was used at 43 stations to determine temperature, salinity and chloro...

description In August and November 2012, two hydrographic surveys were conducted in the coastal region of the Southern Caribbean of Costa Rica, between the Port of Limon and Gandoca Lagoon. A CTD (conductivity, temperature and depth profiler) was used at 43 stations to determine temperature, salinity and chlorophyll-a. It was determined that spatial and temporary variations of surface temperature were small, with values ranging between 28.6°C and 30°C. In addition, surface salinity ranged between 33.3 and 35.2 PSU and the average spatial distribution of chlorophyll-a concentration in surface waters was 0.64 mg m-3, with maximum and minimum values of 1.1 mg m-3 and 0.19 mg m-3, respectively. The vertical temperature field was characterized by a warm mixed layer (T ~ 29°C), which extended to 60 m deep in November and less than 10 m deep in August. During the two sampled months, from the vertical structure of the isotherms, we found a cyclonic motion (from the surface to 15 m deep) in the region adjacent to Cahuita, and an anticyclonic motion at 20 m in August and 40 m in November. We identified water masses present in the water column to the depths sampled: CSW, 0-80 m and SSW, > 80 m.

Se utilizó un CTD (perfilador de conductividad, temperatura y profundidad) en 43 estaciones para determinar la temperatura, salinidad y clorofila-a. Se encontró que las variaciones espaciales y temporales de la temperatura superficial fueron pequeñas, y los valores se ubicaron entre 28.6°C y 30°C. Asimismo, el rango de salinidades superficiales estuvo entre 33.3 y 35.2 UPS, y la distribución espacial de las concentraciones de clorofila-a en las aguas superficiales presentó un valor promedio de 0.64 mg m-3, con un valor máximo de 1.1 mg m-3 y un mínimo de 0.19 mg m-3. El campo vertical de temperatura se caracterizó por mostrar una capa de mezcla cálida (T ~ 29°C) en ambos meses de muestreo, la cual se extendió hasta los 60 m de profundidad en noviembre y menos de 10 m de profundidad en agosto. En ambos meses de muestreo a partir de la estructura vertical de las isotermas, se encontró un movimiento ciclónico (desde la superficie y hasta los 15 m de profundidad) en la región frente a Cahuita, y un movimiento anticiclónico a partir de los 20 m de profundidad en agosto, y 40 m de profundidad en noviembre. Se identificaron las masas de agua presentes en la columna de agua hasta las profundidades muestreadas: ASC, 0-80 m y ASS,> 80 m.Em agosto e novembro do ano 2012, foram realizadas duas campanhas hidrográficas na zona costeira do Caribe Sul da Costa Rica, entre o Porto de Limón e a Lagoa de Gandoca.
