This paper presents a comprehensive overview of the Moira Mounds in the Porcupine Seabight, combining a review of currently published material with new data and interpretations. The Moira Mounds are circular to ovoid-shaped individual or clustered coral banks (referred to as "scleractinian spaced cluster macroreefs") located in the Belgica (carbonate) mound province, Porcupine Seabight, west of Ireland. They are up to 10 m high and 20 to 35 m in diameter. For the first time, a map showing the complete extent and location of the Moira Mounds is published, revealing 256 examples grouped into four areas mainly between 800 and 1100 m water depth. ROV groundtruthing revealed the importance of bedload sand transport in Moira Mound formation and development... |

New marine geological data of Cuban shelf were obtained during Cuban-Soviet Expedition of 1964-1965. The micro and macrofauna and substancial composition were studied. Bentonic foraminifera appeared over 100 m depth in the Gulf of Mexico. The muds were the most caracteristic sediment of the Caribbean Sea. The composition or rare rock was studied in the Yucatan Strait. With a big content of Si, Al, Mg, Ca, Fe and Ti was noted a low content of Na. This is not characterisc on eruptioned calcareous rocks. |

El presente estudio realiza un análisis morfoestructural de las plataformas que están en el territorio marìtimo ecuatoriano:(1)La Plataforma de las Islas Galápagos que es producto de la interacción entre el Punto Caliente de Galápagos y el Centro de Divergencia de Galápagos, y (2) La Plataforma Continental del Ecuador continental localizada en un margen activo convergente entre la placa oceánica de Nazca y los segmentos continental de la placa Sudamericana y del Bloque Norandino. Mediante el uso de Sistemas de Información Geográfica (SIG) y Modelos Digitales de Terreno (MDT), se caracterizó morfológicamente la proyección de la plataforma continental hacia el segmento marino, para luego realizar una confrontación entre el área que incluye la plataforma... |

The Ecuadorian shoreline is considered highly susceptible to tsunamis events of tectonic origin due to its closeness to the Nazca and South America plates subduction zone. Since 1906, eight tsunamis events have been witnessed along this coast. All have been related to seismic activity (earthquakes between Ms 6.9 to 8.9) on or near the Ecuadorian platform. Such tectonic environment favours the generation and surge of tsunamis in this region. The study area is located in the outer area of the lower basin of the Guayas River, in what is referred as the Canton General Villamil Playas. Three cores were retrieved from the supratidal coastal plain around Villamil at different horizontal distances from the Pacific shoreline. Villamil 1 was cored at 1128 m from... |

Holocene age-depth data from the Belgian coastal plain, basal peat data particularly, are assessed in terms of local water and tide levels. Basal peat formation was generally induced by sea-level rise; effects of local seepage were limited and significant river-gradient effects were absent. No relation was found between the timing of basal peat inception and substrate permeability. In general, edaphic (moisture) conditions were unfavourable for organic accumulation prior to sea-level related rise of the groundwater table. Error envelopes for the minimum level of local mean high water spring tides and for upper and extreme lower relative mean sea-level limits during the last 9400 solar years (8400 yrs B.P.) are presented. These indicate that the rate of... |
