Variabilidad hidroclimática en el Golfo de Batabanó, Cuba
Provedor de dados: 20
Autores: Piñeiro, R.; Cobas, S.; Fernández, L.
An study of hydroclimate variability in the region of the gulf of Batabanó analyzing the water and air monthly temperatures series from 1982 to 2008 was carried out. The correlation between both variables were r = 0,87 and was obtained an equation that allow to reconstruct the water temperature series from 2003 until 2008.The water temperature average was 27,60 ºC, with standard deviations of 1,496. In the anomalies fluctuations are observed warm and cold periods. The maximum positive anomalies appear in 1997-1998 and 2002-2003. In the transformed series of the annual water temperature average, a tendency to the temperature increase at the end of the 1990´s is obtained, until the 2008. The transformed series of the air temperature average had warming and...

Caso de Estudio No. 2: Estado de la pesquería de la langosta espinosa (Panulirus argus) y su relación con factores ambientales y antrópicos en Cuba
Provedor de dados: 20
Autores: Puga, R.; Piñeiro, R.; Capetillo, N.; de León, M.E.; Cobas, S.
Las capturas de langosta espinosa Panulirus argus (Latreille, 1804) en Cuba alcanzaron sus mayores  volúmenes en la década de 1980 con un promedio anual de 11565 ton. En la década de 1990, la captura  descendió a un promedio de 9327 ton, lo cual se ha visto agudizado entre 2000 y 2007 con un promedio  de 6262 ton y una mayor variabilidad de las capturas, a pesar de un perfeccionamiento del sistema de  manejo pesquero dado por: la disminución del esfuerzo pesquero y de la tasa de mortalidad por pesca  desde 1999, el aumento del período de veda desde 2001 y el incremento gradual de la talla mínima  legal de captura a partir de 2004.    Los análisis más recientes sobre el estado de esta pesquería fueron presentados en el Quinto Taller  Regional sobre la...

El transporte Ekman: un posible factor en la entrada de puerulos de P. argus en la plataforma suroccidental  de Cuba
Provedor de dados: 20
Autores: Piñeiro, R.; León, M. E.; Puga, R.; Cobas, S.
An study of the Ekman transport in the adjacient oceanic region to the suroccidental shelf of the gulf of Batabanó between 82,5º and 81,5º of west longitude and 21,5º and 19,5º of north latitude it was carried out. This is a zone of great importance of being one of the main sites of pueruli onshore to the shelf shallow waters. The monthly analysis of the transport between 1967 and 2006 establishes water onshore to the shelf, with remarkable increases related to the influence of hurricanes Gilbert (1988), Mitch (1998), Iván and Charlie (2004) and Olga (2007). The seasonal pattern showed values superior to the averages from September to November, which indicates greater oceanic water offshore, related with greater pueruli entrance. Between April and August,...

Variabilidad de la temperatura superficial del mar obtenida a partir de imágenes AVHRR y su relación con las pesquerías de langosta (Panulirus argus) en las aguas Cubanas (1997-2004)
Provedor de dados: 20
Autores: Duthit Somoza, R.; Kampel, M.; Buss Souza, R.; Cobas, S.
Resumen Se obtiene la variabilidad espacial y temporal de la temperatura superficial del mar (TSM) para las aguas de la plataforma cubana, así como la relación de estas con las capturas de langostas, en el período comprendido entre Enero/1997-Diciembre/2004. Los datos de de esta variable ambiental son obtenidos del sensor “Advanced Very High Resolution Radiometer” (AVHRR). La periodicidad de las imágenes y de los datos de captura por zonas de pesca es mensual. Las aguas oceánicas y de la plataforma tienen un comportamiento estacional para la TSM, alcanzando las máximas en Agosto (29,5°C) y las mínimas en Febrero (26°C). Los valores extremos registrados se datan en Agosto del 1998 con anomalías de 1,9°C y de -0,9°C en Febrero del 2001. Durante el período...

Lobster (panulirus argus) captures and their relation with environmental variables obtained by orbital sensors for cuban waters (1997-2005).
Provedor de dados: 20
Autores: Duthit Somoza, R.; Kampel, M.; de Moraes Rudorff, F.; Sousa, R.B.; Cobas, S.
(SeaWIFS) ocean color monthly images, Sea Surface Temperature (SST) pathfinder data obtained from the Advanced Very High Resolution Radiometer (AVHRR) sensors, and lobster (Panulirus argus) captures at the Cuban shelf were examined in order to analyze their spatial and temporal variability. A cross-correlation analysis was made between the standardized anomalies of the environmental variables (Chl a and SST) and the standardized anomalies of lobster captures for each fishery zones for the period between 1997 and 2005. For the deep waters adjacent to the fishing zones it was not observed a clear Chl a seasonality and on average the lowest values occurred south of the Island. It is with the three years lag that Chl a had the greatest numbers of significant...
