    Description: The anthropogenic affectation was evaluated on the coast N of the Gulf of Batabanó in May 2003 (corresponding to the provinces of Matanzas and Havana), in areas located in the line of the coast. The results were compared with the historical information of the sector. In the coast N and the Ensenada of the Broa, the parameters oxygen saturation, DBO5 and DQO showed characteristic high values of eutrofication. The biggest contribution in the Cianoficies was in the near coastal areas to sources of organic contamination. In the case of the nutrients they show specific data of mesothrofic waters with tendency to the eutrofization and the silts presented a high affectation for toxic metals. The area near to Guanímar is distinguished to present conditions of organic contamination that favor heterothrofic conditions, corroborated by a prevalence of the processes of mineralization of the organic matter over primary production and lows values of fitoplankton concentration. On the contrary, in the region of Surgidero of Batabanó, the processes of synthesis of organic matter prevail suggested by a high primary production, and concentration of fitoplankton, with low breathing levels and mineralization of the organic matter, that indicates that the system is behaving autothrofically. In a general way, this sector is very affected by the anthropogenic impact. The information obtained is of great importance for the development of the fishing and tourist industries in the area.

    Description: Se reconoce que el establecimiento y operación de un sistema de monitoreo ambiental es la médula de los esfuerzos que una nación realiza en el campo del manejo de la calidad del medio ambiente y sin él, los programas de restauración y protección de los recursos naturales, solo pueden alcanzar objetivos limitados con una efectividad relativa. A partir de los análisis de la información correntométrica obtenida de dos ADCP (Y5 y Y6) fondeados en el Lado Cuba del canal de Yucatán desde septiembre de 1999 a junio de 2001, es obtenida una caracterización espacio-temporal de la contracorriente cubana. Los resultados muestran un flujo al Sur de forma intermitente, sufriendo variaciones tanto en su envergadura como en su intensidad en los diferentes meses del año. De forma general, los estratos superficiales y subsuperficiales se caracterizan por presentar los mayores valores de la velocidad de la corriente, llegando en ocasiones hasta los 136 cm/s. La velocidad tiende a disminuir con la profundidad y generalmente los niveles inferiores se caracterizan por velocidades entre 0-10 cm/s aunque es frecuente que la corriente alcance valores superiores a 20 cm/s. En el mes de abril de 2000 se observó la mayor persistencia de la contracorriente cubana en ambas zonas con 85 % en Y6 y 81 % en Y5.
