    Description: Abstract: An analysis of sea level synoptic variations in the Gulf of Batabanó is carried out starting from data of direct measurements. Spectral analysis is applied. It is corroborated with new elements the prevalence of meteorological variations in part of the southwestern shelf, and the spectral structure of this shelf is characterized. The influence of meteorological factors is evaluated. It is demonstrated the influence exerted by the southern component of the wind on this variations. There are signs of the possible influence of ENSO on sea level monthly variability at La Coloma; and there is a great similarity between this variability and that of Siboney.

    Description: Series cronológicas de nivel del mar obtenidas durante el año 2004 en tres estaciones mareaográficas ubicadas en la costa noroccidental de Cuba muestran en las frecuencias bajas, ω 〈 0.2 ciclos por día (cpd), una propagación hacia el E con velocidad de fase de una onda baroclínica de Kelvin (2-3 m/s). La coherencia entre las localidades alcanza sus valores máximos en la banda de los 0.1-0.2 cpd. Estos resultados permiten verificar la existencia de ondas atrapadas a la costa en la zona de estudio.
    Description: Time series of sea level during 2004, from three tide gauges located in the NW coast of Cuba, show that in low frequencies, ω 〈 0.2 cycles per day (cpd), fluctuations propagate eastward with the phase speed of baroclínic Kelvin wave (2-3 m/s). The alongshore coherence reaches its maximum values in the frequency band of 0.1-0.2 cpd. These results allow verifying the existence of coastal-trapped waves in the study zone.

    Description: Se realizaron cinco muestreos entre enero de 2007 y junio de 2008 a la zona costera del municipio Playa, con el fin de evaluar los contenidos de los compuestos del ciclo del carbono. Los parámetros estudiados en la matriz agua fueron carbón orgánico, pH, alcalinidad total, alcalinidad al carbonato, dióxido de carbono total, dióxido de carbono libre, presión parcial de CO2, y contenidos de bicarbonato y carbonato. Los compuestos de carbono orgánico e inorgánico tuvieron una distribución muy heterogénea, los valores de pH (8,24±0,22) y alcalinidad total (2523±119 μmol/kg) indican que el área tiene un comportamiento alcalino, estos montos fueron similares a los encontrados en aguas de la plataforma marina cubanos y superiores a los consignados para el ambiente oceánico. El bicarbonato constituye el 77 % del carbono inorgánico total.
    Description: Five samplings were carried out between January 2007 and June 2008 in the coastal zone of Playa Municipality, with the purpose of evaluating the contents of carbon cycle compounds. The studied water matrix parameters were organic carbon, pH, total alkalinity, carbonate alkalinity, total carbon dioxide, free carbon dioxide, partial CO2 pressure, and bicarbonate and carbonate contents. Organic and inorganic carbon compounds presented a very heterogeneous distribution; pH values (8,24±0,22) and total alkalinity (2523±119 μmol/kg) indicate that the area has an alkaline behavior. These values were similar to those found in waters of the Cuban marine shelf, and higher than those registered for the oceanic environment. Bicarbonate ions constitute 77% of the total inorganic carbon.

    Description: The subinertial response of sea level to meteorological forcing in the Gulf of Mexico is examined using observations of sea level, atmospheric pressure and surface wind covering the period 1985-1986. Spectral analysis and multiple regression in the frequency domain methods are employed for data processing. The analysis shows that the atmospheric pressure is the principal forcing agent. The response of sea level to atmospheric pressure is found to be non isostatic and dependent on frequency and geographical location; the response is overisostatic in the north zone and underisostatic in the south zone of the Gulf, approaching isostasy only at stations located in the Cuban coast. The importance of local and remote wind in sea level variability are determined; it is found an effective zone of sea level forcing due to the wind on the West Florida Shelf.

    Description: Sediments in deep ocean trenches may contain crucial information on past earthquake history and constitute important sites of carbon burial. Here we present 14C data on bulk organic carbon (OC) and its thermal decomposition fractions produced by ramped pyrolysis/oxidation for a core retrieved from the 〉7.5 km-deep Japan Trench. High-resolution 14C measurements, coupled with distinctive thermogram characteristics of OC, reveal hemipelagic sedimentation interrupted by episodic deposition of pre-aged OC in the trench. Low δ13C values and diverse 14C ages of thermal fractions imply that the latter material originates from the adjacent margin, and the co-occurrence of pre-aged OC with intervals corresponding to known earthquake events implies tectonically triggered, gravity-flow-driven supply. We show that 14C ages of thermal fractions can yield valuable chronological constraints on sedimentary sequences. Our findings shed new light on links between tectonically driven sedimentological processes and marine carbon cycling, with implications for carbon dynamics in hadal environments.
