| Se describe la morfología, composición y estructura de la formación coralina desarrollada alrededor de Isla Arena, un pequeño islote localizado en la zona central de la plataforma continental del Caribe colombiano. A partir de fotografías aéreas del área y observaciones en el campo, se elaboraron mapas batimétricos, de las unidades de fondo, de acuerdo al sustrato y a la cobertura de la biota sésil dominante, del grado de exposición al oleaje y de sus patrones de dispersión y refracción. Mediante el empleo de una cámara de video submarina, se filmaron transectos a lo largo de una cadena de 10 m, que fueron analizados usando el método de punto intersectado para la caracterización de la estructura de la comunidad de organismos sésiles. Un total de 33... |

| The geologic (stratigraphic) and morphodynamic characteristics throughout 76 km of the coastal profile of the Colombian Caribbean, including those between Barranquilla (Bocas de Ceniza) and the spit of Galerazamba are described. The sections of the coast that have been affected by erosive events and those with sedimentary accretion are described. Some of them are associated to both natural and anthropic phenomena. Geologically, the coastal edge is defined by sedimentary rocks, weakly consolidated sediments and inconsolidated sediments, that include ages from the upper Paleocene to the Recent. From the point of view of the evaluation of the coast in terms of stability and instability, the high coasts are classified as: Critic zones (Punta Sabanilla,... |

| Forty-eight bottom sediments samples collected from the Bonny estuary were analyzed for textural Characteristics and organic carbon content. The dominant lithologies are sand, sandy mud, mud, sandy clay and clay. Pattern of sediment distribution consists of mud, sandy mud and clay in the swallow marginal areas of the river channel and creeks, while the channel centers are predominantly fine to coarse sand with graphic mean size ranging from 0.74 to 2.71Ø. Inclusive standard deviation values ranged from 0.35 to 1.64Ø suggesting the poorly to very well sorted nature of these sediments. Skewness varied from fine skewed to strong coarse skewed with 52% of the samples negatively skewed. Graphic kurtosis ranged from 0.92 to1.95 [mesokurtic to very leptokurtic].... |
