dc.description.abstractSpatial and temporal variation of Chromophoric Dissolved Organic Matter (CDOM) absorption was studied in the course of diverse research cruises through the Caribbean region. CDOM absorption and spectral slopes showed marked seasonal and spatial variability. Temporal trends showed maximum mean surface CDOM absorption and spectral slopes during summer. The spatial analysis showed highest absorption values in the Gulf of Paria. Values remained relatively high along the Orinoco River Plume throughout the Eastern Caribbean. High values were also found along the edges of a cyclonic eddy with entrained Orinoco River Plume waters. Values outside of the plume were found to be low. Differences found on spectral slopes point to spatialtemporal differences in water mass sources in the Caribbean. Mesoscale eddies affect the spatial and temporal distribution of CDOM by advection of the Amazon and Orinoco River plumes into the Eastern Caribbean basin creating complex mosaics of optically clear and optically dense waters.en_US
dc.description.abstractSe estudiaron las variaciones espaciotemporales de la absorción de materia orgánica disuelta coloreada (MODC) durante diversos cruceros de investigación a través de la región del Caribe. Tanto la absorción como las pendientes espectrales mostraron marcada variabilidad estacional y espacial. Las tendencias temporales mostraron un máximo de absorción promedio de MODC durante el verano en superficie. El análisis espacial mostró valores máximos de absorción en el Golfo de Paria. Los valores se mantuvieron relativamente altos a lo largo de la pluma de descarga del Río Orinoco en todo el Caribe Oriental. También se encontraron valores altos a lo largo de los bordes de un remolino ciclónico que arrastraba aguas de la pluma del río Orinoco. Se encontraron valores bajos fuera de la pluma. Diferencias encontradas en las pendientes espectrales apuntan a diferencias espaciotemporales en la naturaleza de las fuentes de masas de agua en el Caribe. Los remolinos de mesoescala afectan la distribución especial y temporal de MODC por advección de las plumas de los ríos Amazonas y Orinoco a la cuenca del Caribe Oriental creando complejos mosaicos de aguas ópticamente claras con aguas ópticamente densas.en_US
